Though based in Austria, Project Manaia conducts marine research at sea, arranging expeditions and providing a floating research platform for scientists, students, and ocean lovers alike. After a couple of successful years in the Mergui Archipelago in Myanmar, they turned their focus to the Mediterranean Sea where they sourced a 43-foot Sailboat for research. Their projects include plastic pollution, invasive species and seagrass – they have created an invasive species map and seagrass map to detect how far invasive species in the Mediterranean spread and where the seagrass meadows are disappearing. Supporting citizen science, they encourage the public to contribute with their sightings.

Project Seagrass is an marine conservation charity advancing the conservation of seagrass through education, influence, research and action. The organization is dedicated to ensuring that seagrass meadows are protected globally, for the biodiversity and people that depend on them, directly or indirectly.

Formerly Global Wildlife Conservation, Re:wild aims to protect wildlife by protecting and restoring biodiversity in every sphere, thereby protecting the planet from 'the triple threat of climate change, extinction and pandemics. This includes the ecosystems which impact on ocean life, such as corals reefs, mangroves, seagrasses, amongst others.

Operating in Madagascar, Reefdoctor is a UK based charity working on conservation and social development projects, including coral reefs, mangroves, turtles, marine pollution, fisheries, aquaculture and education

ResilienSEA is a project which focuses on seagrass in West Africa. The goal of the ResilienSEA project is to build capacity and increase knowledge in seven West African countries to better manage and conserve their seagrass beds. The project is in Senegal, Sierra Leone, Cape Verde, Guinea Conakry, Guinea Bissau and the Gambia with the sole objective to "conserve sea-grass to save marine diversity and enhance socio-economic development. The status of this project at this point is unclear.

Roots of the Sea is an environmental conservation group which works to protect the natural environment on the island of Martinique, with a particular focus on mangroves.

Running Tide describes itself as a global ocean health company. With the mission of healing healing climate-damaged fisheries and of capturing carbon, they aim to sequester carbon in seaweed grown on wooden buoys, then sunk in deep water. Running Tide’s idea is to fight climate change by growing macroalgae—seaweed—on tiny ocean floats made from waste wood coated with calcium carbonate. As the carbon-rich seaweed grows, it weighs down its buoy and eventually sinks, depositing all that carbon on the seabed. This research is currently being conducted in Iceland.

The Safe Seaweed Coalition is a global partnership established to oversee the safety and sustainability of the seaweed industry as it scales up, supported through the investment of our three major partners. As the Coalition develops, its members will represent the entire seaweed value chain – from smallholder farmers to multinational businesses, specialized research institutes to intergovernmental organisations – working together to realize the full potential of the seaweed industry and to ensure its safety for consumers, for workers and for the environment.

The Sea Change Project are a community of scientists, storytellers, journalists and filmmakers who are dedicated to raising awareness of the beauty and ecological importance of South Africa’s kelp forest.

Sea Forest is an environmental technology company based in Tasmania, Australia cultivating seaweed which is native to the island, as a natural solution to climate change. The seaweed farm works on multiple climate solutions by reducing CO2 emissions in the livestock and dairy industries. At the same time, the seaweed, Asparagopsis, through photosynthesis, captures carbon from the atmosphere which makes up 40% of its biomass.

sea4soCiety aims at developing innovative and societally accepted approaches to improve the natural potential for carbon storage in coastal ecosystems. sea4soCiety is one of six research consortia within the research mission “Marine carbon sinks in decarbonization pathways” of the German Marine Research Alliance (DAM). The project will determine the blue carbon potential of coastal ecosystems along the Wadden Sea and Baltic Sea coasts (focusing on saltmarsh, seagrass, and seaweed) as well as in tropical Colombia and Indonesia (focusing on mangroves, saltmarsh, and seagrass). sea4soCiety is itself a consortium of ten research institutions across northern Germany, operating under the auspices of CDRmare.

Seaforestation.co specializes in deepwater irrigation services and equipment and the commercialization and sale of seaweed products, beginning with biostimulants, food and feed. By accessing nutrients found in the deep ocean, deepwater irrigation helps mitigate against the impacts of marine heatwaves and builds in climate resilience while extending the growing season, thereby achieving greater productivity and yields, while dramatically increasing cultivable ocean area.
