Coastwatch Europe (CWE) protects wetlands by raising public awareness of their value, and demonstrating practical ways to save them. CWE is an international network of environmental groups, universities and other educational institutions, who in turn work with local groups and individuals around the coast of Europe. Coastwatch Europe has participated at hundreds of events since the 1980’s, facilitates surveys of the coast, litter, seaweed, and advocates for Marine Protected Areas, amongst other actions.

Conservación ConCiencia is a non-profit organization in Puerto Rico dedicated to environmental research and conservation that aims to promote sustainable development by working collaboratively with communities, governments, academia and the private sector. Their mission is to implement effective, science based conservation actions that move our societies towards sustainability. Conservación ConCiencia focuses on projects in Puerto Rico and Cuba, including the following: Puerto Rico’s first shark research and conservation program in collaboration with the seafood industry; analyzing parrotfish supply chain and its market in Puerto Rico; promoting commercial fisheries exchange between Puerto Rico and Cuba with lessons learned from successful fisheries management and promoting Cuban fishers access to local markets for entrepreneurial opportunities. Another example of their work is a large scale restoration of mangroves and seagrass project, in collaboration with The Ocean Foundation.

International Conservation Ecuador has been working for 20 years for the conservation of natural ecosystems and services to ensure the human well-being of current and future generations. Their marine programmes include protection of the ocean while innovating new ways to sustain marine fisheries. Together with the Ministry of the Environment and Water in Ecuador, this involves promoting the effective management of marine and coastal protected areas, the conservation of mangroves and the management of coastal fisheries.

Conservation International Philippines has worked with the government and local communities to value and protect healthy ecosystems since 1995. Part of Conservation International, their aim is to protect nature and ​provide innovative solutions to key environmental issues – such as the loss of mangroves, deforestation, climate change, unsustainable fishing and the illegal wildlife trade. With its extensive coastline and reliance on fishing, the marine component of their work is significant.

Coralive.org focuses on 'coral reef restoration and protection, management of marine protected areas, conservation education and developing alternative livelihood programs for coastal communities'. They have developed a method to accelerate coral growth and enhance coral resiliency via mineral accretion technology. Their coral restoration projects are active in Jamaica, Madagascar, Kenya, Seychelles, Maldives and Philippines. Seagrass and mangroves are also in their sights, with replantings and transplanting projects underway in places such as the Maldives. They are also involved in MPA management in Madagascar.

The Cornwall Wildlife Trust is a charitable organisation founded in 1962 that is concerned solely with Cornwall, England. It deals with the conservation and preservation of Cornwall's wildlife, geology and habitats managing over 50 nature reserves covering approximately 4,300 acres, amongst them Looe Island. They are actively involved in marine conservation, with extensive training of volunteers to monitor marine mammals, respond to strandings, and survey of marine environments. A recent project to restore Cornwall’s seagrass meadows in the Fal Estuary has attracted attention, amidst their many other projects protecting life on the land and in the sea.

CostaSalvaje/Wildcoast is an international group that aims to conserve the coastal and marine ecosystems and wildlife around California and Latin America. They are fighting to conserve more than 31.9 million acres of globally significant wild coastlines, islands, lagoons, and oceans. Through educating local communities, advocating for conservation policies, and establishing and managing protected areas, Wildcoast is trying to reduce the impact of climate change, conserve coral reefs, prioritize sewage treatment, and protect wetlands and coastal wildlands.

DEEPWAVE e.V. was founded in 2003 by the marine biologist and deep sea researcher Onno Groß and a small group of ocean enthusiasts in Hamburg. Since then, it has successfully campaigned regionally and internationally for the protection of the oceans and their inhabitants. DEEPWAVE's goal is to contribute to the development of environmentally friendly structures for the marine ecosystem, as well as to inspire individuals to conserve the oceans. They do this by raising awareness of the threats to the oceans, spreading scientific knowledge, contributing to improve marine policies, and providing a forum for networking.

The German Foundation for Marine Conservation is a group of committed animal welfare and nature conservation advocates, who fight for the protection of threatened marine animals and the preservation of marine habitats. They support and carry out projects, campaigns, and initiatives aimed at conserving marine life. This includes marine & nature conservation; animal welfare; science and research; and development cooperation. Since 2022 they have had a long term eDNA Project on Fiji-Island to identify habitats of guitarfish species and of young bullsharks. They support projects to protect sharks, rays, sea turtles and marine mammals, restoration of coral reefs and seagrass beds, for sustainable fishing and ocean cleanups. Their educational and awareness-raising work aims at anchoring the importance of marine conservation in people's minds and actions.

The Dugong and Seagrass Conservation Project aims to enhance the conservation of dugongs (Dugong dugon) and their associated seagrass ecosystems in eight countries in the Indo-Pacific region : Indonesia, Madagascar, Malaysia, Mozambique, Solomon Islands, Sri Lanka, Timor-Leste and Vanuatu. A priority of the project is to work with local communities to help them understand the benefits of conserving dugongs and their habitat. They focus on sustainable fisheries practices and financial incentives, establishing Locally Managed Marine Protected Areas, and advocating for dugong and seagrass conservation as priorities in national and regional policies and planning. This is a GEF funded project, lasting from 2015-2018.

The Dugong & Seagrass Hub is an online platform designed to share collective tools, experiences and lessons learned whilst working to conserve seagrass ecosystems in dugong range states. This is run out of the UNEP Environment Agency, Convention on Migratory Species Office in Abu Dhabi.

Fearless Fund harnesses our ocean’s tremendous potential to produce energy and sustainable products while pioneering the removal of carbon dioxide (CDR). The Fearless team assists the health of our systems while producing economically viable and sustainable biomass in the ocean. Biomass grown in the ocean saves costly inputs of land-based agriculture. The US DOE ARPA-E funds the Fearless Fund-led team of US National Labs, marine engineers and universities testing an initiative to harvest floating macroalgae for renewable fuel, CO2 removal and the Blue Economy. Fearless Fund pioneers the scale-up of ocean-based plant production as an alternative energy source and an important contribution to a more sustainable economy. The process reduces excess nutrient runoff, therefore benefitting the health of various marine ecosystems.
