Under the general aim of 'Sustainability through transparency in global fishing activity', Global Fishing Watch is the result of a partnership between Oceana, SkyTruth and Google that 'identifies apparent fishing activity and provides the world's first global view of commercial fishing'. It is an online tool that allows anyone in the world to see what 35,000 of the world’s largest commercial fishing vessels are doing, and to track them in near-real time, for free. 'Our purpose is to create and publicly share knowledge about human activity at sea to enable fair and sustainable use of our ocean. We use cutting-edge technology to turn big data into actionable information. We believe human activity at sea should be common knowledge in order to safeguard the global ocean for the good of all.'

GulfBase is a free, searchable database of people, places, projects, events and organizations in the Gulf of Mexico. It includes information about the Gulf of Mexico, including: its bays and estuaries; reefs, banks and islands; environmental issues; institutions and organizations; people; and an InfoHub with articles on the laws, the science, and socioeconomic issues relevant to management and use of the Gulf; and a Mexican coral reef species checklist. GulfBase aims to be 'a resource for a broad audience of knowledge-seekers: From scientists seeking new collaborators to students researching a science project'.

HappyWhale offers the opportunity to contribute to science through photography of marine mammals. Through its web platform, happywhale.com, images are shared, and individual whales identified, and contributors are notified of who their whale is, as well as of future resightings of their whale. HappyWhale has identified almost every individual humpback whale in the North Pacific Ocean, and has built a global database of over 68000 individuals. This information helps with whale rescue response to entanglement, understanding population change, and education about the world’s whales. An evolving project.

Innoceana is a young international team of professional scuba-divers, engineers, biologists, conservationists and ocean lovers, who work on innovative solutions to protect the ocean. To overcome the problems of lack of knowledge and resources within communities, the interdisciplinary team works on developing low-cost and accessible methods that allow locals to play an active role in monitoring the ocean, thus empowering citizen science. Examples of projects include sea currents monitoring, water quality in Isla del Cano, 3D Coral Reef monitoring, 2D GIS mapping, plastic monitoring, turtle identification, interactive books, amongst others. Raising awareness and educating is an important element of their mission, with the recently opened MCEC in Costa Rica an example of their approach achieving effective marine conservation. Innoceana is registered in Costa Rica, California and Spain.

With the ever increasing amount of marine construction around the world encroaching on shorelines and destroying natural habitats, Living Seawalls have come up with an innovative solution: combining engineering with ecological concerns, they have created specially designed tiles which are attached to sea walls to create habitats for marine life to attach to. As of October 2021 they have installations in Australia, Singapore, Gibraltar and Wales. Living Seawalls is a program of the Sydney Institute of Marine Science and collaborates with Reef Design Lab. Finalist in the Revive our Oceans category of the 2021 Earthshot award.

Based in Ojochal, Costa Rica, the MCEC is a Marine Conservation and Education Center founded by the non-profit organization Innoceana. Their mission is ‘to rewild the ocean with innovation and education’. The center offers marine focused marine conservation expeditions for divers, by helping the MCEC team carry out hands-on research and conservation projects, all while enjoying and exploring the marine hotspots of the Osa Peninsula. Single-day experiences, multi-day expeditions, internship opportunities, dive training, and more, including beach clean-ups.

Manta Matcher is a global online database for manta rays. It is one of the Wildbook Web applications developed by Wild Me, created in partnership with Dr. Andrea Marshall of the Marine Megafauna Foundation. Manta rays have unique spot patterning on their undersides, which allows for individual identification. Scuba divers upload their manta identification photographs to the Manta Matcher website, supporting global research and conservation efforts. Manta Matcher is a pattern-matching software. This citizen science tool is free to use by researchers worldwide.

Marine Protection Atlas is the only comprehensive database that identifies and tracks fully and highly protected MPAs throughout the world. Highly informative, the MPAtlas supports international marine conservation initiatives by integrating science-based assessments that measure progress toward protecting 30% of the global ocean in fully and highly protected areas by 2030. This application was created by the Marine Conservation Institute in partnership with Astute Spruce, LLC and EcoQuants LLC

Mr. Trash Wheel is a stationary vessel positioned in the Baltimore River to catch marine debris before it reaches the harbour. Powered by its water wheels and solar panels, it is operated by a human crew.

Nekton Foundation is a marine research organisation dedicated to exploring and protecting the deep ocean. Nekton leads research expeditions and conducts the Ocean Health Check, deploying the latest human operated submersibles and deep sea technology to obtain ‘scientific data and media content to amplify ocean prioritisation, accelerate ocean literacy and inform organisations mandated with regional and international marine protection and stewardship. Nekton’s research catalyses the increase of Marine Protected Areas, improvements in marine resource management, pollution reduction, climate change mitigation and changes to consumer behaviour.’ They have conducted expeditions in Bermuda, Weddell's Sea, Indian Ocean in Seychelles and Maldives, amongst others.

NeMO-Net is a single player iPad game where players help NASA classify coral reefs by painting 3D and 2D images of coral. Players explore and classify coral reefs and other shallow marine environments and creatures from locations all over the world

Data from the NeMO-Net game is fed to NASA NeMO-Net, the first neural multi-modal observation and training network for global coral reef assessment. NeMO-Net is an opensource deep convolutional neural network (CNN) that leverages NASA’s Supercomputer, Pleiades, to use game data to classify and assess the health of coral reefs around the world.

The NetTag approach to the problem of marine litter derived from fisheries combines two different types of preventive measures: new technology to prevent lost gears; and awareness actions to promote best-practices for on-board waste management. NetTag is developing new technologies to track fishing gears in case gears got lost, fostering a reduction of lost gears. The technology involves low cost, miniature and environmental-friendly acoustic tags and acoustic transceivers for uniquely localization (with fisher’s personal ID) of lost gear and an automated-short-range robotic recovery system. This is an active project co-ordinated by Ciimar in Portugal.
