4Ocean manufactures and sells bracelets made from recycled materials, as well as apparel and water bottles. The company uses a portion of the profits to remove one pound of trash from the ocean and coastlines for each bracelet that is sold in an effort to clean up plastic pollution in oceans. Now operating in several countries around the world, 4Ocean employs people to collect trash from the ocean and beaches, and organises beach cleanups by volunteers. It is an award-winning company, gaining recognition for its entrepreneurial success. They are currently at work in Bali and Java, Indonesia; Haiti; Guatemala and Hawaii, USA. In addition, they have created The 4Ocean Learning Center as a resource 'for teachers, students, businesses, and any ocean enthusiast who wants to learn more about the ocean plastic crisis and be part of the solution to plastic pollution.'

AIDA is a pioneer organization working on environmental protection in some of the world’s most vulnerable communities and critically endangered habitats. Established in 1998, AIDA uses the law and science to protect sensitive ecosystems and communities suffering from environmental harm, primarily in Latin America. Marine projects they are involved in include campaigning to end subsidies which promote overfishing, protection of species which are important for coral reefs, protecting the ocean from threats such as mining and overdevelopment of shores. Active in: Argentina, Canada, Chile, Costa Rica, Ecuador, Mexico, Peru, USA.

ARCAS was originally created by Guatemalan citizens for a very specific and urgent purpose: to build a rescue center to care for and rehabilitate wild animals that were being confiscated on the black market by the Guatemalan government. Since the establishment of the Rescue Center in Peten, ARCAS has branched out into environmental education, protected areas management, marine turtle conservation, mangrove protection, sustainable community development, ecotourism and reforestation. ARCAS’s three main project sites are: the Guatemala City area, the remote northern department of Petén, and the Hawaii area of the southern Pacific Coast. They are a member of WIDECAST

Ocean conservation educational initiative taken up by a 7 years old from Minnesota named Aeon. In first quarter since the birth of the organization, it presented the awareness to more than 250 youngers in several educational institutes. The initiative continues to grow and to educate kids about the ocean.

The African Aquatic Conservation Fund is dedicated to the preservation of African manatees, turtles, cetaceans, and other aquatic wildlife and their habitats throughout the African continent. This is done via focused research, conservation, and education projects. The Fund works in close partnership with local people, scientists, governments, and other stakeholders for the benefit of both wildlife and humans.

Alaska Marine Conservation Council is a community-based, non-profit organization committed to protecting the long-term health of Alaska's marine ecosystems and sustaining the working waterfronts of the state's coastal communities.

AOOS provides coastal and ocean observations, forecasts, and data information products that address regional and national needs for ocean information and ensure timely and sustained dissemination and availability of these data.

Alaska Ocean Program is an environmental consultant (included here as the name suggests a public interest group but it is in fact a commercial enterprise)

The Alaska Wilderness League works to protect Alaska's most significant wild lands from oil and gas drilling and from other industrial threats. The members include fishermen, subsistence harvesters, marine scientists, business owners, conservationists, families, and others who care deeply about Alaska's oceans.

The Alexandria Turtle and Wildlife Rescue Team focuses on protecting wild animals in their natural habitats, in particular sea turtles

AMRF is dedicated to the preservation of the marine environment, specifically to the problem of plastic pollution. Algalita was the first to spearhead the research methodology for collecting and analyzing micro/macroplastic samples from the ocean. Since Captain Moore's 1997 discovery of the 'plastic soup' in the North Pacific Gyre, AMRF have continued collecting samples through multiple expeditions in the North Pacific and around the world, including in the Southern Hemisphere in Chile and the South Pacific. Their current focus is on youth education.

The Allen Coral Atlas maps and monitors the world's coral reefs to provide actionable data and a shared understanding of coastal ecosystems. In 2017, the Atlas was developed through a unique international partnership of remote sensing, conservation, and coral ecology experts who harnessed satellite imagery, machine learning, and big data processing to capture the first high-resolution view of the world's coral reefs.
Now, the full suite of Allen Coral Atlas tools provides a comprehensive and unprecedented picture of changes to coral reefs over time, giving scientists, decision-makers, and the reef management community critically important information urgently needed for rapid response and conservation. The Atlas system is instrumental in spatial planning, protected area management, reef restoration, and coastal protection/disaster risk reduction. (Scubavox note: Check out the great maps and videos on their website.)
The Allen Coral Atlas is an international collaborative partnership, managed by Arizona State University, other past and current partners include Planet Labs, The Arizona State University, The University of Queensland’s Remote Sensing Research Centre, the National Geographic Society and Vulcan Inc.
