SeaDataNet is an international project of oceanography, with the main goal of enabling the scientific community to access historical datasets owned by national data centers. SDN provides a distributed Marine Data Infrastructure for the management of large and diverse sets of data deriving from in situ of the seas and oceans. The project is pan-European, and the access is to multidisciplinary ocean and marine data, data products and metadata services. Their website includes the European Directory of Marine Organisations EDMO

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.

Invented by Australian surfers, The Seabin Project provides solutions to remove pollution in waterways before it reaches the ocean. The V5 Seabin unit is a “trash skimmer” designed for marinas, yacht clubs, harbours, ports and any water body with a calm environment and suitable services available. The unit acts as a ' floating garbage bin skimming the surface of the water by pumping water into the device'. The Seabin V5 like a floating trash can that is effective in harbours and bays to collect floating debris, including micro plastics and micro fibres with an additional filter. The rim lies just beneath the surface of the water so nearby floating junk is pulled in. It uses a pump to act like a sinkhole and allow water flow to continue. Humans nearby need to check and empty it often.

Founded in 2014, Sustainable Ocean Alliance (SOA) activates young people, develops and implements innovative solutions, and ‘mobilizes an ocean workforce to restore the health of the ocean in our lifetime’. By supporting innovative startups, nonprofits, and grassroots campaigns through publicity, funding and grants, they are actively working on solving the problems faced by the oceans, including via technological and scientific solutions. As of 2021, they had become involved in 222 initiatives all over the world, each dedicated to restoring and sustaining the health of our ocean focusing on the following 5 general categories of solutions: Carbon (CO2) reduction and blue carbon; Pollution reductions and the circular economy; Blue Foods (Sustainable protein, fisheries and aquaculture); Ocean data, literacy and research; and Ecosystem preservation and restoration.

The Sea Cleaners work on solutions against marine plastic pollution on land and at sea. They are ‘fighting on all fronts: awareness and prevention, the dissemination of scientific knowledge, the transition to a circular economy, and the collection of waste on land and at sea.’ They collect floating plastic waste in high concentration areas before it sinks or breaks down into microplastics, and develop innovative collection and reuse solutions of plastic waste in the sea. They currently have a vessel, the Mobula 8 which collects macro- and micro-waste for pollution control and research, and are currently developing The Manta, a giant sailing boat/factory ship capable of collecting, processing and recovering large quantities of marine plastic waste. Their mission also includes scientific research and awareness raising against plastic pollution, encouraging volunteers worldwide to join clean-up operations in calm and protected waters - port and lake areas, mangroves, rivers, canals and the sea up to 5 miles from the coast.

The Tangaroa Research Institute of Oceanographic Studies (TriOceans) is a marine research institute based on the North Island of New Zealand, describing themselves as ‘a collective of scientists and innovators’. They focus on marine mammal science and engineering, with a view to producing quality research and new technologies, while inspiring conservation through education.

Wild Me builds open software and artificial intelligence for the conservation research community, which enables the contribution of citizen science. Their software programme Wildbook, automatically identifies individual animals by their unique coat patterns or other hallmark features, such as fluke or ear outlines. It was started off to improve the tracking of whale sharks which was previously done by attaching plastic tags to the animals that had often never resurfaced. The platform has since grown into a vast database of various different species, including sea turtles, manta rays, sharks, whales, dolphins, big cats, giraffes and zebras.

eOceans is a collaborative scientific initiative in Canada. It focuses on informing ocean conservation efforts with “crowd-sourced” data. Marine citizen scientists, ocean industry professionals and others who actively explore the blue planet and make important observations every day can participate. The data is collected and combined with traditional and expert datasets to build a comprehensive ecological baseline of marine environments all over the world. eOceans provides a simple way for divers, snorkelers, paddle boarders, beach goers and even fishermen to report the sharks, rays and sawfish they observe for conservation. These observations or lack of observations are used to assess and monitor populations, communities, and ecosystems. Most importantly the data is used to assess the need for marine sanctuaries, and monitor marine management initiatives already in place.
Previous eOceans survey results have been used for several publications to assist with shark conservation. Results from eShark have been used to assist the IUCN data of sharks for the Convention of International Trade of Endangered Species (CITES). Marine biologist and researcher Dr. Christine Ward-Paige is the leading researcher and data analyst for eOceans
