Ocean Conservancy (founded as The Delta Corporation) is a nonprofit environmental advocacy group based in Washington, D.C., United States.

The conservancy's main concern was to restore sustainable American fisheries and protect wildlife from human impact.

In 1979, the organization established the Seal Rescue Fund (SRF) to protect marine mammals from commercial exploitation.

The main event of the organization is the International Coastal Cleanup, a day where over 150 countries gather to clean up beaches and oceans.

[17] The movement was created by Linda Maraniss and Kathy O'Hara in 1986 when they organized the Ocean Conservancy's first local cleanup event.

Alaska Chadux̂ Network (ACN) has continuously pioneered and refined solutions to reduce the risk of marine oil spills.

IBR assisted ACN in developing a response trailer designed for rapid mobilization and care of injured birds and small mammals.

Like ASLC, IBR also provides bird care professionals and support equipment to assist in the rehabilitation of oiled wildlife.

[21] The Trash Free Seas Alliance was established by the Ocean Conservancy in 2012, with the participation of significant enterprises such as The Coca-Cola Company, PepsiCo, and Amcor, as well as non-profit organizations like the World Wildlife Fund and the Project AWARE Foundation.

[3] The primary objective of the alliance is to combat marine litter via scientific investigation, policy advocacy, and public outreach.

The aim was to provide essential information on marine plastics to scientists, policymakers, teachers, students, and the general public.
