A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways , carrying goods or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats , based on size, shape, load capacity, and tradition.
In the Age of Sail a " ship " was a sailing vessel defined by its sail plan of at least three square rigged masts and a full bowsprit. Ships have supported exploration , trade , warfare , migration , colonization , and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world population growth.
As of , there were more than 49, merchant ships , totaling almost 1. Ships are generally larger than boats, but there is no universally accepted distinction between the two.
Ships generally can remain at sea for longer periods of time than boats. In the Age of Sail , a full-rigged ship was a sailing vessel with at least three square-rigged masts and a full bowsprit ; other types of vessel were also defined by their sailplan , e.
A number of large vessels are usually referred to as boats. Submarines are a prime example. In most maritime traditions ships have individual names , and modern ships may belong to a ship class often named after its first ship. In the northern parts of Europe and America a ship is traditionally referred to with a female grammatical gender , represented in English with the pronoun "she", even if named after a man.
This is not universal usage and some English language journalistic style guides advise using "it" as referring to ships with female pronouns can be seen as offensive and outdated.
The first sea-going sailing ships were developed by the Austronesian peoples from what is now Taiwan. Their invention of catamarans , outriggers , and crab claw sails enabled their ships to sail for vast distances in open ocean. It led to the Austronesian Expansion at around to BC.
From Taiwan, they rapidly colonized the islands of Maritime Southeast Asia , then sailed further onwards to Micronesia , Island Melanesia , Polynesia , and Madagascar , eventually colonizing a territory spanning half the globe. Austronesian rigs were distinctive in that they had spars supporting both the upper and lower edges of the sails and sometimes in between , in contrast to western rigs which only had a spar on the upper edge. Their designs were unique, evolving from ancient rafts to the characteristic double-hulled, single-outrigger, and double-outrigger designs of Austronesian ships.
Early Austronesian sailors influenced the development of sailing technologies in Sri Lanka and Southern India through the Austronesian maritime trade network of the Indian Ocean , the precursor to the spice trade route and the maritime silk road , which was established at around BC.
In the 1st century AD, the people from Nusantara archipelago already made large ships over 50 m long and stood out 4�7 m out of the water. They could carry people and ton cargo. It has masts and able to sail against the wind due to the usage of tanja sails.
These ships reaching as far as Ghana. In China, miniature models of ships that feature steering oars have been dated to the Warring States period c. Sternpost-mounted rudders started to appear on Chinese ship models starting in the 1st century AD. In BC, Ancient Egyptians learned how to assemble wooden planks into a hull.
The ancient Egyptians were perfectly at ease building sailboats. A remarkable example of their shipbuilding skills was the Khufu ship , a vessel feet 44 m in length entombed at the foot of the Great Pyramid of Giza around BC and found intact in The oldest discovered sea faring hulled boat is the Late Bronze Age Uluburun shipwreck off the coast of Turkey, dating back to BC.
By B. In world maritime history, declares Richard Woodman, they are recognized as "the first true seafarers, founding the art of pilotage, cabotage, and navigation" and the architects of "the first true ship, built of planks, capable of carrying a deadweight cargo and being sailed and steered.
At this time, ships were developing in Asia in much the same way as Europe. It is likely that the Mongols of the time took advantage of both European and Asian shipbuilding techniques.
In Japan, during the Sengoku era from the fifteenth to 17th century, the great struggle for feudal supremacy was fought, in part, by coastal fleets of several hundred boats, including the atakebune.
The "turtle ship", as it was called is recognized as the first armored ship in the world. Until the Renaissance , navigational technology remained comparatively primitive compared to Austronesian cultures. Examples include the maritime republics of Genoa and Venice , Hanseatic League , and the Byzantine navy. The Vikings used their knarrs to explore North America , trade in the Baltic Sea and plunder many of the coastal regions of Western Europe.
Towards the end of the 14th century, ships like the carrack began to develop towers on the bow and stern. These towers decreased the vessel's stability, and in the 15th century, the caravel , designed by the Portuguese , based on the Arabic Small Commercial Fishing Boat Plans Inc qarib which could sail closer to the wind, became more widely used.
This increased freeboard allowed another innovation: the freeing port , and the artillery associated with it. The carrack and then the caravel were developed in Portugal.
After Columbus, European exploration rapidly accelerated, and many new trade routes were established. These explorations in the Atlantic and Indian Oceans were soon followed by France , England and the Netherlands , who explored the Portuguese and Spanish trade routes into the Pacific Ocean , reaching Australia in and New Zealand in Parallel to the development of warships, ships in service of marine fishery and trade also developed in the period between antiquity and the Renaissance.
Maritime trade was driven by the development of shipping companies with significant financial resources. Canal barges, towed by draft animals on an adjacent towpath , contended with the railway up to and past the early days of the industrial revolution. Flat-bottomed and flexible scow boats also became widely used for transporting small cargoes.
Mercantile trade went hand-in-hand with exploration, self-financed by the commercial benefits of exploration. During the first half of the 18th century, the French Navy began to develop a new type of vessel known as a ship of the line , featuring seventy-four guns. This type of ship became the backbone of all European fighting fleets. These ships were 56 metres ft long and their construction required 2, oak trees and 40 kilometres 25 mi of rope; they carried a crew of about sailors and soldiers.
During the 19th century the Royal Navy enforced a ban on the slave trade , acted to suppress piracy , and continued to map the world. A clipper was a very fast sailing ship of the 19th century. The clipper routes fell into commercial disuse with the introduction of steam ships with better fuel efficiency, and the opening of the Suez and Panama Canals.
Ship designs stayed fairly unchanged until the late 19th century. The industrial revolution, new mechanical methods of propulsion , and the ability to construct ships from metal triggered an explosion in ship design. Factors including the quest for more efficient ships, the end of long running and wasteful maritime conflicts, and the increased financial capacity of industrial powers created an avalanche of more specialized boats and ships.
Ships built for entirely new functions, such as firefighting, rescue, and research, also began to appear. In , the world's fleet included 51, commercial vessels with gross tonnage of more than 1, tons , totaling 1. In , there were 1, warships operating in the world, not counting small vessels such as patrol boats. The United States accounted for 3 million tons worth of these vessels, Russia 1.
The 20th century saw many naval engagements during the two world wars , the Cold War , and the rise to power of naval forces of the two blocs. The world's major powers have recently used their naval power in cases such as the United Kingdom in the Falkland Islands and the United States in Iraq. The size of the world's fishing fleet is more difficult to estimate. The largest of these are counted as commercial vessels, but the smallest are legion.
Fishing vessels can be found in most seaside villages in the world. As of , the United Nations Food and Agriculture Organization estimated 4 million fishing vessels were operating worldwide. Because ships are constructed using the principles of naval architecture that require same structural components, their classification is based on their function such as that suggested by Paulet and Presles, [43] which requires modification of the components.
The categories accepted in general by naval architects are: [44]. Freshwater shipping may occur on lakes, rivers and canals. Ships designed for those venues may be specially adapted to the widths and depths of specific waterways. Examples of freshwater waterways that are navigable in part by large vessels include the Danube , Mississippi , Rhine , Yangtze and Amazon Rivers, and the Great Lakes.
Lake freighters , also called lakers, are cargo vessels that ply the Great Lakes. These vessels are traditionally called boats, not ships. Visiting ocean-going vessels are called "salties. Because the smallest of the Soo Locks is larger than any Seaway lock, salties that can pass through the Seaway may travel anywhere in the Great Lakes. Because of their deeper draft, salties may accept partial loads on the Great Lakes, "topping off" when they have exited the Seaway.
Similarly, the largest lakers are confined to the Upper Lakes Superior , Michigan , Huron , Erie because they are too large to use the Seaway locks, beginning at the Welland Canal that bypasses the Niagara River. Since the freshwater lakes are less corrosive to ships than the salt water of the oceans, lakers tend to last much longer than ocean freighters.
Lakers older than 50 years are not unusual, and as of , all were over 20 years of age. SS St. Marys Challenger , built in as William P Snyder , was the oldest laker still working on the Lakes until its conversion into a barge starting in Similarly, E.
Ford , built in as Presque Isle , was sailing the lakes 98 years later in As of E. Ford was still afloat as a stationary transfer vessel at a riverside cement silo in Saginaw, Michigan. Merchant ships are ships used for commercial purposes and can be divided into four broad categories: fishing, cargo ships , passenger ships , and special-purpose ships.
Modern commercial vessels are typically powered by a single propeller driven by a diesel or, less usually, gas turbine engine. The fastest vessels may use pump-jet engines.
Special-purpose vessels often have specialized crew if necessary, for example scientists aboard research vessels.
Fishing boats are generally small, often little more than 30 meters 98 ft but up to metres ft for a large tuna or whaling ship. Aboard a fish processing vessel , the catch can be made ready for market and sold more quickly once the ship makes port.
Special purpose vessels have special gear. For example, trawlers have winches and arms, stern-trawlers have a rear ramp, and tuna seiners have skiffs. In , 85,, tonnes 84,, long tons ; 94,, short tons of fish were caught in the marine capture fishery. Modern commercial fishermen use many methods. One is fishing by nets , such as purse seine , beach seine, lift nets, gillnets , or Small Commercial Fishing Boat Plans Mac entangling nets. Another is trawling , including bottom trawl. Hooks and lines are used in methods like long-line fishing and hand-line fishing.
Another method is the use of fishing trap. Cargo ships transport dry and liquid cargo. Dry cargo can be transported in bulk by bulk carriers , packed directly onto a general cargo ship in break-bulk, packed in intermodal containers as aboard a container ship , or driven aboard as in roll-on roll-off ships. Liquid cargo is generally carried in bulk aboard tankers, such as oil tankers which may include both crude and finished products of oil, chemical tankers which may also carry vegetable oils other than chemicals and gas carriers , although smaller shipments may be carried on container ships in tank containers.
Passenger ships range in size from small river ferries to very large cruise ships. This type of vessel includes ferries , which move passengers and vehicles on short trips; ocean liners , which carry passengers from one place to another; and cruise ships , which carry passengers on voyages undertaken for pleasure, visiting several places and with leisure activities on board, often returning them to the port of embarkation.
Riverboats and inland ferries are specially designed to carry passengers, cargo, or both in the challenging river environment. Rivers present special hazards to vessels. They usually have varying water flows that alternately lead to high speed water flows or protruding rock hazards.
Changing siltation patterns may cause the sudden appearance of shoal waters, and often floating or sunken logs and trees called snags can endanger the hulls and propulsion of riverboats. Riverboats are generally of shallow draft, being broad of beam and rather square in plan, with a low freeboard and high topsides. Riverboats can survive with this type of configuration as they do not have to withstand the high winds or large waves that are seen on large lakes, seas, or oceans. Fishing vessels are a subset of commercial vessels, but generally small in size and often subject to different regulations and classification.
They can be categorized by several criteria: architecture, the type of fish they catch, the fishing method used, geographical origin, and technical features such as rigging. As of , the world's fishing fleet consisted of some 4 million vessels. A weather ship was a ship stationed in the ocean as a platform for surface and upper air meteorological observations for use in marine weather forecasting.
Surface weather observations were taken hourly, and four radiosonde releases occurred daily. The weather ship crews were normally at sea for three weeks at a time, returning to port for day stretches. The last weather ship was Polarfront , known as weather station M "Mike" , which was put out of operation on 1 January Weather observations from ships continue from a fleet of voluntary merchant vessels in routine commercial operation.
Naval vessels are those used by a navy for military purposes. There have been many types of naval vessel. Modern naval vessels can be broken down into three categories: surface warships , submarines , and auxiliary ships. Modern warships are generally divided into seven main categories: aircraft carriers , cruisers , destroyers , frigates , corvettes , Small Commercial Fishing Boat Plans Jump submarines and amphibious assault ships.
The distinction between cruisers, destroyers, frigates, and corvettes is not rigorous; the same vessel may be described differently in different navies.
Battleships were used during the Second World War and occasionally since then the last battleships were removed from the U. Naval Vessel Register in March , but were made obsolete by the use of carrier-borne aircraft and guided missiles. Most military submarines are either attack submarines or ballistic missile submarines. With the development of the homing torpedo , better sonar systems, and nuclear propulsion , submarines also became able to effectively hunt each other.
The development of submarine-launched nuclear and cruise missiles gave submarines a substantial and long-ranged ability to attack both land and sea targets with a variety of weapons ranging from cluster munitions to nuclear weapons.
Most navies also include many types of support and auxiliary vessel, such as minesweepers , patrol boats , offshore patrol vessels , replenishment ships , and hospital ships which are designated medical treatment facilities.
Fast combat vessels such as cruisers and destroyers usually have fine hulls to maximize speed and maneuverability. Some components exist in vessels of any size and purpose. Every vessel has a hull of sorts. Every vessel has some sort of propulsion, whether it's a pole, an ox, or a nuclear reactor. Most vessels have some sort of steering system. Other characteristics are common, but not as universal, such as compartments, holds, a superstructure, and equipment such as anchors and winches. For a ship to float, its weight must be less than that of the water displaced by the ship's hull.
A vessel may have a single hull called a monohull design , two in the case of catamarans , or three in the case of trimarans. Vessels with more than three hulls are rare, but some experiments have been conducted with designs such as pentamarans. Multiple hulls are generally parallel to each other and connected by rigid arms.
Hulls have several elements. The bow is the foremost part of the hull. Many ships feature a bulbous bow. The keel is at the very bottom of the hull, extending the entire length of the ship. The rear part of the hull is known as the stern , and many hulls have a flat back known as a transom. Common hull appendages include propellers for propulsion, rudders for steering, and stabilizers to quell a ship's rolling motion. Other hull features can be related to the vessel's work, such as fishing gear and sonar domes.
Hulls are subject to various hydrostatic and hydrodynamic constraints. The key hydrostatic constraint is that it must be able to support the entire weight of the boat, and maintain stability even with often unevenly distributed weight. Hydrodynamic constraints include the ability to withstand shock waves, weather collisions and groundings. Older ships and pleasure craft often have or had wooden hulls. Steel is used for most commercial vessels.
Aluminium is frequently used for fast vessels, and composite materials are often found in sailboats and pleasure craft. Some ships have been made with concrete hulls. Propulsion systems for ships fall into three categories: human propulsion, sailing , and mechanical propulsion.
Human propulsion includes rowing , which was used even on large galleys. Propulsion by sail generally consists of a sail hoisted on an erect mast, supported by stays and spars and controlled by ropes. Sail systems were the dominant form of propulsion until the 19th century. They are now generally used for recreation and competition, although experimental sail systems, such as the turbosails , rotorsails , and wingsails have been used on larger modern vessels for fuel savings.
Mechanical propulsion systems generally consist of a motor or engine turning a propeller , or less frequently, an impeller or wave propulsion fins.
Steam engines were first used for this purpose, but have mostly been replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Nuclear reactors producing steam are used to propel warships and icebreakers , and there have been attempts to utilize them to power commercial vessels see NS Savannah. In addition to traditional fixed and controllable pitch propellers there are many specialized variations, such as contra-rotating and nozzle-style propellers.
Most vessels have a single propeller, but some large vessels may have up to four propellers supplemented with transverse thrusters for maneuvring at ports. The propeller is connected to the main engine via a propeller shaft and, in case of medium- and high-speed engines, a reduction gearbox.
Some modern vessels have a diesel-electric powertrain in which the propeller is turned by an electric motor powered by the ship's generators.
For ships with independent propulsion systems for each side, such as manual oars or some paddles , [note 3] steering systems may not be necessary. In most designs, such as boats propelled by engines or sails, a steering system becomes necessary. The most common is a rudder, a submerged plane located at the rear of the hull. Rudders are rotated to generate a lateral force which turns the boat.
Rudders can be rotated by a tiller , manual wheels, or electro-hydraulic systems. Autopilot systems combine mechanical rudders with navigation systems. Ducted propellers are sometimes used for steering. Some propulsion systems are inherently steering systems. Examples include the outboard motor , the bow thruster , and the Z-drive.
Larger boats and ships generally have multiple decks and compartments. Separate berthings and heads are found on sailboats over about 25 feet 7. Fishing boats and cargo ships typically have one or more cargo holds. Most larger vessels have an engine room, a galley , and various compartments for work.
Tanks are used to store fuel, engine oil, and fresh water. Ballast tanks are equipped to change a ship's trim and modify its stability. Superstructures are found above the main deck. On sailboats, these are usually very low. On modern cargo ships, they are almost always located near the ship's stern. On passenger ships and warships, the superstructure generally extends far forward. Shipboard equipment varies from ship to ship depending on such factors as the ship's era, design, area of operation, and purpose.
Some types of equipment that are widely found include: [ citation needed ]. Ships float in the water at a level where mass of the displaced water equals the mass of the vessel, such that the downwards force of gravity equals the upward force of buoyancy. As a vessel is lowered into the water its weight remains constant but the corresponding weight of water displaced by its hull increases.
If the vessel's mass is evenly distributed throughout, it floats evenly along its length and across its beam width. A vessel's stability is considered in both this hydrostatic sense as well as a hydrodynamic sense, when subjected to movement, rolling and pitching, and the action of waves and wind. Stability problems can lead to excessive pitching and rolling, and eventually capsizing and sinking.
The advance of a vessel through water is resisted by the water. This resistance can be broken down into several components, the main ones being the friction of the water on the hull and wave making resistance. To reduce resistance and therefore increase the speed for a given power, it is necessary to reduce the wetted surface and use submerged hull shapes that produce low amplitude waves.
To do so, high-speed vessels are often more slender, with fewer or smaller appendages. The friction of the water is also reduced by regular maintenance of the hull to remove the sea creatures and algae that accumulate there. Antifouling paint is commonly used to assist in this. Advanced designs such as the bulbous bow assist in decreasing wave resistance. A simple way of considering wave-making resistance is to look at the hull in relation to its wake. At speeds lower than the wave propagation speed, the wave rapidly dissipates to the sides.
As the hull approaches the wave propagation speed, however, the wake at the bow begins to build up faster than it can dissipate, and so it grows in amplitude. Since the water is not able to "get out of the way of the hull fast enough", the hull, in essence, has to climb over or push through the bow wave. This results in an exponential increase in resistance with increasing speed. The hull is now starting to climb its own bow wave, and resistance begins to increase at a very high rate. For large projects with adequate funding, hydrodynamic resistance can be tested experimentally in a hull testing pool or using tools of computational fluid dynamics.
Vessels are also subject to ocean surface waves and sea swell as well as effects of wind and weather. These movements can be stressful for passengers and equipment, and must be controlled if possible. The rolling movement can be controlled, to an extent, by ballasting or by devices such as fin stabilizers.
Pitching movement is more difficult to limit and can be dangerous if the bow submerges in the waves, a phenomenon called pounding. Sometimes, ships must change course or speed to stop violent rolling or pitching. A ship will pass through several stages during its career. The first is usually an initial contract to build the ship, the details of which can vary widely based on relationships between the shipowners , operators, designers and the shipyard.
Then, the design phase carried out by a naval architect. Then the ship is constructed in a shipyard. After construction, the vessel is launched and goes into service.
Ships end their careers in a number of ways, ranging from shipwrecks to service as a museum ship to the scrapyard. A vessel's design starts with a specification, which a naval architect uses to create a project outline, assess required dimensions, and create a basic layout of spaces and a rough displacement.
After this initial rough draft, the architect can create an initial hull design, a general profile and an initial overview of the ship's propulsion. At this stage, the designer can iterate on the ship's design, adding detail and refining the design at each stage. The designer will typically produce an overall plan, a general specification describing the peculiarities of the vessel, and construction blueprints to be used at the building site.
Designs for larger or more complex vessels may also include sail plans, electrical schematics, and plumbing and ventilation plans. As environmental laws are becoming more strict, ship designers need to create their design in such a way that the ship, when it nears its end-of-term, can be disassembled or disposed easily and that waste is reduced to a minimum. Ship construction takes place in a shipyard , and can last from a few months for a unit produced in series, to several years to reconstruct a wooden boat like the frigate Hermione , to more than 10 years for an aircraft carrier.
During World War II , the need for cargo ships was so urgent that construction time for Liberty Ships went from initially eight months or longer, down to weeks or even days. Builders employed production line and prefabrication techniques such as those used in shipyards today. Hull materials and vessel size play a large part in determining the method of construction.
The hull of a mass-produced fiberglass sailboat is constructed from a mold, while the steel hull of a cargo ship is made from large sections welded together as they are built.
Generally, construction starts with the hull, and on vessels over about 30 meters 98 ft , by the laying of the keel. This is done in a drydock or on land. Once the hull is assembled and painted, it is launched. The last stages, such as raising the superstructure and adding equipment and accommodation, can be done after the vessel is afloat.
Once completed, the vessel is delivered to the customer. Ship launching is often a ceremony of some significance, and is usually when the vessel is formally named. Ships undergo nearly constant maintenance during their career, whether they be underway, pierside, or in some cases, in periods of reduced operating status between charters or shipping seasons. Most ships, however, require trips to special facilities such as a drydock at regular intervals.
Tasks often done at drydock include removing biological growths on the hull, sandblasting and repainting the hull, and replacing sacrificial anodes used to protect submerged equipment from corrosion.
Major repairs to the propulsion and steering systems as well as major electrical systems are also often performed at dry dock. Some vessels that sustain major damage at sea may be repaired at a facility equipped for major repairs, such as a shipyard.
Ships may also be converted for a new purpose: oil tankers are often converted into floating production storage and offloading units. Most ocean-going cargo ships have a life expectancy of between 20 and 30 years. A sailboat made of plywood or fiberglass can last between 30 and 40 years. Solid wooden ships can last much longer but require regular maintenance. Carefully maintained steel-hulled yachts can have a lifespan of over years. As ships age, forces such as corrosion, osmosis, and rotting compromise hull strength, and a vessel becomes too dangerous to sail.
At this point, it can be scuttled at sea or scrapped by shipbreakers. Ships can also be used as museum ships , or expended to construct breakwaters or artificial reefs. The lake has been plagued with a number of invasive species , including zebra [49] and quagga mussels, the goby and the grass carp.
One estimate was that there have been invasive species in the Great Lakes, some having traveled in ballast water in international ships. Environmentalists and biologists study lake conditions via installations such as the Franz Theodore Stone Laboratory on Gibraltar Island. The lab, which was established in , is the oldest biological field station in the United States.
Other invasive species in Lake Erie include: spiny water fleas , fishhook water fleas , sea lamprey , and white perch. The invasive plant species in Lake Erie consist mainly of Eurasian milfoil , Trapa natans and purple loosestrife. An ongoing concern is that nutrient overloading from fertilizers, human and animal waste, known as eutrophication , in which additional nitrogen and phosphorus enter the lake, will cause plant life to "run wild and multiply like crazy".
The algal blooms result from growth of Microcystis , a toxic blue-green algae that the zebra mussels, which infest the lake, will not eat. There periodically is a dead zone , or region of low oxygen, in the lake, the location of which varies. Scientists from the National Oceanic and Atmospheric Administration have been studying the lake's blue-green algae blooms and trying to find ways to predict when they are spreading or where they might make landfall; typically the blooms arrive late each summer.
Army Corps of Engineers determined that the eutrophication was caused by point sources such as industrial outfalls and municipal sanitary and storm sewer outfalls, as well as diffuse sources, such as overland runoff from farm and forest land.
All of these sources contribute nutrients, primarily phosphorus, to the lake. Growth of organisms in the lake is then spiked to the point that oxygen levels are depleted. Recommendations were made for reducing point source outflows, as well as reducing farm contributions of phosphorus by changing fertilizer usage, employing no-till farming and other conservative practices. Many industrial and municipal sources have since then been greatly reduced.
The improved farming practices, which were voluntary, were followed for a while, resulting in remarkable recovery of the lake in the s. The conservation practices are not monitored and have not been kept up. One recent account suggests that the seasonal algae blooms in Lake Erie were possibly caused by runoff from cities, fertilizers, zebra mussels, and livestock near water. Algae blooms continued in early , but new farming techniques, climate change and even a change in Lake Erie's ecosystem make phosphorus pollution more intractable.
According to a news report in August, "scientists fully expect [it] to overwhelm much of western Lake Erie again this summer". Water testing was being conducted in August. In early August, the bloom was expected to measure 7. The Lake Erie water snake, a subspecies of the northern water snake Nerodia sipedon , lives in the vicinity of Ohio's Put-in-Bay Harbor and had been placed on the threatened species list.
In , a local TV station's Doppler weather radar detected millions of mayflies heading for Presque Isle in blue and green splotches on the radar in clouds measuring ten miles 16 km long.
There have been incidents of birds dying from botulism , in [92] and in Lake Erie infamously became very polluted in the s and s as a result of the quantity of heavy industry situated in cities on its shores, with reports of bacteria-laden beaches and fish contaminated by industrial waste.
There were incidents of the oily surfaces of tributary rivers emptying into Lake Erie catching fire: in , Cleveland's Cuyahoga River erupted in flames, [97] chronicled in a Time magazine article which lamented a tendency to use rivers flowing through major cities as "convenient, free sewers"; [56] the Detroit River caught fire on another occasion. Each day, Detroit, Cleveland and other municipalities fill Erie with 1. These chemicals act as fertilizer for growths of algae that suck oxygen from the lower depths and rise to the surface as odoriferous green scum Commercial and game fish�blue pike, whitefish, sturgeon, northern pike�have nearly vanished, yielding the waters to trash fish that need less oxygen.
Weeds proliferate, turning water frontage into swamp. In short, Lake Erie is in danger of dying by suffocation. In December a federal grand jury investigation led by U. Attorney Robert Jones began, of water pollution allegedly being caused by about 12 companies in northeastern Ohio. The grand jury indicted four corporations for polluting Lake Erie and waterways in northeast Ohio. Facing fines were Cleveland Electric Illuminating Co. Mitchell gave a press conference December 18, , referencing new pollution control litigation, with particular reference to work with the Environmental Protection Agency , and announcing the filing of a lawsuit that morning against the Jones and Laughlin Steel Corporation for discharging substantial quantities of cyanide into the Cuyahoga River near Cleveland.
The clearing of the water column is partly the result of the introduction and rapid spread of zebra mussels from Europe, which had the effect of covering the lake bottom, with each creature filtering a liter of fresh water each day, helping to restore the lake to a cleaner state. The lake has since become clean enough to allow sunlight to infiltrate its water and produce algae and sea weed, but a dead zone persists. Coli contaminations, [] possibly caused by sewer water overflows after heavy downpours.
Since the s environmental regulation has led to a great increase in water quality and the return of economically important fish species such as walleye and other biological life. The globs of oil, the multicolored industrial discharges, the flotsam from shoreline cities, the fecal and bacterial wastes are no longer dumped in the lakes in vast quantities.
Joint U. There was a tentative exploratory plan to capture CO 2 , compress it to a liquid form, and pump it a half-mile m beneath Lake Erie's surface underneath the porous rock structure.
Lake Erie is home to one of the world's largest freshwater commercial fisheries. Lake Erie's fish populations are the most abundant of the Great Lakes, partially because of the lake's relatively mild temperatures and plentiful supply of plankton , which is the basic building block of the food chain. Common non-indigenous fish species include the rainbow smelt , alewife , white perch and common carp. Non-native sport fish such as rainbow trout and brown trout are stocked specifically for anglers to catch.
Attempts failed to stock coho salmon , and its numbers are dwindling. Commercial landings are dominated by yellow perch and walleye, with substantial quantities of rainbow smelt and white bass also taken. Anglers target walleye and yellow perch, with some effort directed at rainbow trout. In the s and s, as pollution in the lake declined, counts of walleyes which were caught grew from , in to 4. The combination of overfishing and the eutrophication of the lake by pollution caused the population to collapse, and in the mids, the blue walleye was declared extinct.
But the Lake Erie walleye was reportedly having record numbers, even in , according to one report. There have been concerns about rising levels of mercury in walleye fish; a study by the Canadian Ministry of the Environment noted an "increasing concentration trend" but that concentrations were within acceptable limits established by authorities in Pennsylvania.
The longest fish in Lake Erie is reportedly the sturgeon which can grow to 10 feet 3. Estimates vary about the fishing market for the Great Lakes region. Commercial fishing in Lake Erie has been hurt by pollution as well as government regulations which limit the size of their catch; one report suggested that the numbers of fishing boats and employees had declined by two-thirds in recent decades.
The other feared the lake was being emptied. Commercial fishing is now predominantly based in Canadian communities, with a much smaller fishery�largely restricted to yellow perch �in Ohio.
The Ontario fishery is one of the most intensively managed in the world. However, there are reports that some Canadian commercial fishermen are dissatisfied with fishing quotas and have sued the government about this matter, and there have been complaints that the legislative body writing the quotas is dominated by the U. Still, the commercial fishery is the target of critics who would like to see the lake managed for the exclusive benefit of sport fishing and the various industries serving the sport fishery.
According to one report, the Canadian town of Port Dover is the home of the lake's largest fishing fleet. The lake can be thought of as a common asset with multiple purposes including being a fishery. There was direct competition between commercial fishermen and sport fishermen including charter boats and sales of fishing licenses throughout the lake's history, with both sides seeking government assistance from either Washington or Ottawa , and trying to make their case to the public through newspaper reporting.
Management of the fishery is by consensus of all management agencies with an interest in the resource and work under the mandate of the Great Lakes Fishery Commission. The commission makes assessments using sophisticated mathematical modeling systems. The commission has been the focus of considerable recrimination, primarily from angler and charter fishing groups in the U. This conflict is complex, dating from the s and earlier, with the result in the United States that, in , commercial fishing was mostly eliminated from Great Lakes states.
One report suggests that battling between diverse fishing interests began around Lake Michigan and evolved to cover the entire Great Lakes region. The lake supports a strong sport fishery. While commercial fishing declined, sport fishing has remained. The deep cool waters that spawn the best fishing is in the Canadian side of the lake. In , the Pennsylvania Fish and Boat Commission tried stocking the lake with brown trout in an effort to build what's called a put-grow-and-take fishery.
In winter when the lake freezes, many fishermen go out on the ice, cut holes, and fish. It is even possible to build bonfires on the ice. The day began with fishermen setting down wooden pallets to create a bridge over a crack in the ice so they could roam farther out on the lake.
But the planks fell into the water when the ice shifted, stranding the fishermen about 1, yards offshore When fishermen realized late Saturday morning that the ice had broken away, they began to debate the best way off.
Some chose to sit and wait for authorities, while others headed east in search of an ice bridge Others managed to get to land on their own by riding their all-terrain vehicles about five miles east to where ice hadn't broken away.
When the rescued fishermen made it to shore, authorities had them line up single-file to take down their names. The lake's formerly more extensive lakebed creates a favorable environment for agriculture in the bordering areas of Ontario, Ohio, Michigan, Pennsylvania, and New York. The Lake Erie sections of western New York have a suitable climate for growing grapes, and there are many vineyards and wineries in Chautauqua County and Erie County.
The drainage basin has led to well fertilized soil. The north coast of Ohio is widely referred to as its nursery capital. Lake Erie is a favorite for divers since there are many shipwrecks, perhaps 1, to 8, according to one estimate, [36] of which about are confirmed shipwreck locations. There are efforts to identify shipwreck sites and survey the lake floor to map the location of underwater sites, possibly for further study or exploration.
Among the diving community, they are considered world class, offering opportunities to visit an underwater museum that most people will never see. In , the 19th-century paddle steamer Atlantic was discovered. In , the wreckage of Adventure became the first shipwreck registered as an "underwater archaeological site"; when it was discovered that Adventure ' s propeller had been removed and given to a junkyard.
The propeller was reclaimed days before being converted to scrap metal and brought back to the dive site. Dow , the "steamer-cum-barge" Elderado , [] W.

In western Pennsylvania, a wildlife reserve was established in in Springfield Township for hiking, fishing, cross-country skiing and walking along the beach.
In , The New York Times reporter Donna Marchetti took a bike tour around the Lake Erie perimeter, traveling 40 miles 64 km per day and staying at bed and breakfasts. Lake Erie islands tend to be in the westernmost part of the lake and have different characters. Some of them include:. Kayaking has become more popular along the lake, particularly in places such as Put-in-Bay, Ohio. The lake is dotted by distinct lighthouses. A lighthouse off the coast of Cleveland, beset with cold lake winter spray, has an unusual artistic icy shape, although sometimes ice prevents the light from being seen by maritime vessels.
There have been reports of persons spotting a creature akin to the Loch Ness Monster , but there have been no confirmed reports. There have been sporadic reports of people in Cleveland being able to see the Canadian shoreline as if it were immediately offshore, even though Canada is 50 miles 80 km from Cleveland. It has been speculated that this is a weather-related phenomenon, working on similar principles as a mirage.
The lake has been a shipping lane for maritime vessels for centuries. Generally there is heavy traffic on the lake except during the winter months from January through March when ice prevents vessels from traveling safely.
In , there was a protest against Ontario's energy policy which allows the shipping of coal in the lake; Greenpeace activists climbed a ladder on a freighter and "locked themselves to the conveyor belt device that helps to unload the ship's cargo"; three activists were arrested and the ship was delayed for more than four hours, and anti-coal messages were painted on the ship. However, plans to operate a ferryboat between the U. Since the border between the two nations is largely unpatrolled, it is possible for people to cross undetected from one country to the other, in either direction, by boat.
In , Canadian police arrested persons crossing the border illegally from the United States to Canada, near the Ontario town of Amherstburg. From Wikipedia, the free encyclopedia. One of the Great Lakes in North America. For other uses, see Lake Erie disambiguation.
