An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil.
Honolulu Harbor, also called Kulolia and Ke Awa O Kou and the Port of Honolulu, is the principal seaport of Honolulu and the State of Hawaiʻi in the United States. From the harbor, the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oahu. It includes Matson, Inc. harbors on Sand Island.
Falls of Clyde is the last surviving iron-hulled, four-masted full-rigged ship, and the only remaining sail-driven oil tanker. Designated a U.S. National Historic Landmark in 1989, she is now a museum ship in Honolulu, but her condition has deteriorated. She is currently not open to the public. In September 2008, ownership was transferred to a new nonprofit organization, the Friends of Falls of Clyde. Efforts to raise $1.5 million to get the ship into drydock did not succeed. In November 2021 HDOT accepted a bid from Save Falls of Clyde – International (FOCI) to transport the ship to Scotland for restoration.
Environmental issues in the Niger Delta are caused by its petroleum industry. The delta covers 20,000 km2 (7,700 sq mi) within wetlands of 70,000 km2 (27,000 sq mi) formed primarily by sediment deposition. Home to 20 million people and 40 different ethnic groups, this floodplain makes up 7.5% of Nigeria's total land mass. It is the largest wetland and maintains the third-largest drainage basin in Africa. The Delta's environment can be broken down into four ecological zones: coastal barrier islands, mangrove swamp forests, freshwater swamps, and lowland rainforests. Fishing and farming are the main sources of livelihoods for majority of her residents.
Ocean Conservancy is a nonprofit environmental advocacy group based in Washington, D.C., United States. The organization seeks to promote healthy and diverse ocean ecosystems, prevent marine pollution, climate change and advocates against practices that threaten oceanic and human life.
The Great Barrier Reef is the world's largest reef systems, stretching along the East coast of Australia from the northern tip down at Cape York to the town of Bundaberg, is composed of roughly 2,900 individual reefs and 940 islands and cays that stretch for 2,300 kilometres (1,616 mi) and cover an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia. A large part of the reef is protected by the Great Barrier Reef Marine Park.
The Prudhoe Bay oil spill was an oil spill that was discovered on March 2, 2006 at a pipeline owned by BP Exploration, Alaska (BPXA) in western Prudhoe Bay, Alaska. Initial estimates of the five-day leak said that up to 267,000 US gallons (6,400 bbl) were spilled over 1.9 acres (7,700 m2), making it the largest oil spill on Alaska's north slope to date. Alaska's unified command ratified the volume of crude oil spilled as 212,252 US gallons (5,053.6 bbl) in March 2008. The spill originated from a 0.25-inch (0.64 cm) hole in a 34-inch (86 cm) diameter pipeline. The pipeline was decommissioned and later replaced with a 20-inch (51 cm) diameter pipeline with its own pipeline inspection gauge (pig) launch and recovery sites for easier inspection.
SS Maui was built as a commercial passenger ship in 1916 for the Matson Navigation Company of San Francisco and served between the United States West Coast and Hawaii until acquired for World War I service by the United States Navy on 6 March 1918. The ship was commissioned USS Maui (ID-1514) serving as a troop transport from 1918 to 1919. The ship was returned to Matson for commercial service September 1919 and continued in commercial service until purchased by the United States Army in December 1941. USAT Maui was laid up by the Army in 1946 and scrapped in 1948.
The 2009 USS Port Royal grounding was a ship grounding by the United States Navy guided missile cruiser Port Royal off Oahu, Hawaii on 5 February 2009. The ship ran aground on a coral reef, damaging both the ship and the reef. The incident received wide press coverage in Hawaii, in part because of the damage caused to a sensitive coral environment, and also because the stranded ship was within sight of Honolulu off the airport.
The Deepwater Horizon oil spill was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The United States federal government estimated the total discharge at 4.9 MMbbl. After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history.
Human activities have substantial impact on coral reefs, contributing to their worldwide decline.[1] Damaging activities encompass coral mining, pollution, overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays. Additional threats comprise disease, destructive fishing practices, and the warming of oceans.[2] Furthermore, the ocean's function as a carbon dioxide sink, alterations in the atmosphere, ultraviolet light, ocean acidification, viral infections, the repercussions of dust storms transporting agents to distant reefs, pollutants, and algal blooms represent some of the factors exerting influence on coral reefs. Importantly, the jeopardy faced by coral reefs extends far beyond coastal regions. The ramifications of climate change, notably global warming, induce an elevation in ocean temperatures that triggers coral bleaching—a potentially lethal phenomenon for coral ecosystems.
The Red Butte Creek oil spill was caused by a rupture in a medium crude oil pipeline that occurred on June 11 and 12 2010. The Chevron Pipeline (CPL) is 10 inches in diameter and runs from western Colorado to a Chevron Corporation oil refinery near Salt Lake City Utah. A half-inch diameter hole in the pipeline was caused by an electrical arc from high voltage power lines to a metal fence post buried a few inches above the pipeline.
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 of crude oil making it the largest marine oil spill. Both the spill and the cleanup efforts had effects on the environment.
The Deepwater Horizon oil spill occurred between 10 April and 19 September 2010 in the Gulf of Mexico. A variety of techniques were used to address fundamental strategies for addressing the spilled oil, which were: to contain oil on the surface, dispersal, and removal. While most of the oil drilled off Louisiana is a lighter crude, the leaking oil was of a heavier blend which contained asphalt-like substances. According to Ed Overton, who heads a federal chemical hazard assessment team for oil spills, this type of oil emulsifies well. Once it becomes emulsified, it no longer evaporates as quickly as regular oil, does not rinse off as easily, cannot be broken down by microbes as easily, and does not burn as well. "That type of mixture essentially removes all the best oil clean-up weapons", Overton said.
On May 1, 2010, a ruptured ExxonMobil pipeline in the state of Akwa Ibom, Nigeria, spilled more than a million gallons into the delta and contributed to the major environmental issues in the Niger Delta. The spill had occurred at an Exxon platform some 20–25 miles (32–40 km) offshore which feeds the Qua Iboe oil export terminal. Exxon Mobil declared force majeure on Qua Iboe oil shipments due to the pipeline damage. The leakage in the Qua Iboe oil field discharged about 232 barrels of crude into the Atlantic Ocean contaminating the waters and coastal settlements in the predominantly fishing communities along Akwa Ibom and Cross River.
The Refugio oil spill on May 19, 2015, contaminated one of the most biologically diverse areas of the West Coast of the United States with 142,800 U.S. gallons of crude oil. The corroded pipeline that caused the spill closed indefinitely, resulting in financial impacts to the county estimated as high as $74 million as it and a related pipeline remained out of service for three years. The cost of the cleanup was estimated by the company to be $96 million with overall expenses including expected legal claims and potential settlements to be around $257 million.

The Orange County oil spill on October 1, 2021, is an oil spill that deposited crude oil onto popular Southern California beaches on the West Coast of the United States. While residents reported smelling fumes, a ship noticed an oil slick that evening and reported it to federal authorities. When oil from an underwater pipeline in the waters of coastal Orange County began washing ashore, officials in Huntington Beach closed the typically crowded beach in the evening of October 2. The U.S. Coast Guard estimated that spill covered 8,320 acres (3,370 ha) of the ocean's surface as they monitored it several times daily from the air. Investigations found a 17.7-mile (28.5 km) pipeline connecting offshore oil platforms with the shore had been displaced by being dragged by a ship's anchor.
