A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...
The environmental effects of shipping include air pollution, water pollution, acoustic, and oil pollution. [1] Ships are responsible for more than 18% of nitrogen oxides pollution, [2] and 3% of greenhouse gas emissions. [3]
Ballast water discharges by ships can have a negative impact on the marine environment. The discharge of ballast water and sediments by ships is governed globally under the Ballast Water Management Convention, since its entry into force in September 2017. It is also controlled through national regulations, which may be separate from the ...
The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels (210 million US gal; 780,000 m 3) of crude oil making it the largest marine oil spill.

The shipping industry can be harmful to marine habitats by causing disturbances from anchoring and mooring activities, which causes seabed scouring and damage to benthic habitats, including seagrass meadows and coral reefs. [6] Vessel groundings can cause significant damage to coral reefs and soft bottom habitats, altering community structure ...
Emission control area. Emission control areas (ECAs), or sulfur emission control areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI [1] of the 1997 MARPOL Protocol. The emissions specifically include SOx, NOx, ODSs and VOCs [2] and the regulations came into ...
