Ocean pollution can originate from various sources, including oil spills, plastic waste, sewage discharge, and other human activities.

Tanker accidents are the leading cause of oil spills in the ocean, accounting for a significant portion of the total volume of oil spilled.

Oil spills can have devastating effects on marine life, with sea turtles, coral reefs, and seabirds being particularly vulnerable to the toxic effects of oil.

Oil booms and skimmers are commonly used to contain and remove oil from the ocean surface during oil spill cleanup operations.

MARPOL 73/78 (International Convention for the Prevention of Pollution from Ships) is the primary international convention that aims to prevent and control oil pollution from ships.

Biodegradation is the process by which microorganisms break down and utilize oil as a food source, leading to its natural degradation in the environment.

Bunker fuel, a type of heavy oil used in ships, is considered to be the most difficult to clean up due to its high viscosity and persistence in the environment.

The use of chemical dispersants in oil spill cleanup raises concerns about toxicity to marine life, formation of underwater oil plumes, and increased evaporation of oil.

The International Maritime Organization (IMO) is the primary international organization responsible for coordinating global efforts to address oil spills and other marine pollution issues.

In-situ burning is the process of intentionally burning oil spills on the ocean surface as a method of cleanup and disposal.

Bunker fuel, due to its high viscosity and complex composition, is considered to be the most persistent type of oil spill in the environment.

The use of in-situ burning in oil spill cleanup raises concerns about the release of toxic fumes, formation of persistent oil residues, and increased risk of fire spreading.

The Paris Agreement is an international agreement that aims to reduce greenhouse gas emissions from various sources, including ships.

The International Oil Pollution Compensation Funds (IOPC Funds) aims to provide compensation for oil spill damages, promote oil spill prevention and preparedness, and facilitate international cooperation in oil spill response.

Light crude oil, due to its low viscosity and high content of volatile hydrocarbons, is considered to be the most volatile and flammable type of oil spill.
