The Conservation Gateway is an initiative of The Nature Conservancy (TNC) aimed at the conservation practitioner, scientist and decision-maker. In the Gateway, TNC shares the up-to-date information they use to inform their work. The Gateway is organised in three major sections: Conservation Planning, Conservation Practice, and Conservation by Geography.

CI applies innovations in science, economics, policy and community participation to protect the Earth's plant and animal biodiversity in major tropical wilderness areas and key marine ecosystems. CI focuses on securing the critical benefits that nature provides to humanity, such as food, fresh water, livelihoods and a stable climate. An important aspect of CI's work is promoting the dissemination of critical marine information to the global community, in order to 'unify international marine stakeholders through knowledge sharing and information exchange'. Their Center for Oceans partners with communities, organizations and governments around the world.

Conservation International Brazil is part of a global organization that works to protect the environment and promote sustainable development. They have a presence in Brazil and have worked on marine conservation initiatives in the country, including the aim expand Brazil's marine and coastal protected areas, while creating ways to make artisanal fisheries more sustainable. This is achieved by encouraging monitoring and inclusion of coastal ecosystems in environmental policies and promoting better fishing practices.

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.

CI Ventures is an investment fund that provides loans to small- and medium-sized enterprises that operate in the forests, oceans and grasslands where Conservation International works. The fund’s capital supports enterprises that will generate profit, which helps to pay off the loans, thus returning principal and interest to the fund that can be used to make future investments, thus creating a revolving fund in support of conservation worldwide. CI Ventures’ investments emphasize projects that have the potential for greatest impact in critical landscapes and seascapes in Peru, Colombia, Ecuador, Kenya, South Africa, Indonesia and the Philippines.

ConsumerNotice is an organization dedicated to advocating for consumers by raising awareness of health and safety risks linked to defective products, environmental threats, and various hazards. Marine pollution has become a worldwide emergency, with oceans suffering from an overwhelming accumulation of debris. This pollution not only poses significant risks to human health but also endangers marine life. Recognizing the importance of protecting our oceans, Consumer Notice has developed an extensive guide on PFAS found in plastics that contribute to ocean pollution, along with a guide on reducing pollution. For more information, please refer to the website. It is crucial that we take action to protect our oceans, as they play a vital role in maintaining the balance of ecosystems and supporting life on Earth.

CIWR documents population abundance of humpback whales, beaked whales, sperm whales, dolphins, other cetaceans, marine mammals, turtles and sharks through opportunistic and systematic surveys.

Amongst the many free education resources created by Cool Australia is one focused on marine conservation: Ocean Conservation Education Resources. These lessons are all about the ocean, engaging students in ocean science and supporting young people to be active and aware of science-driven research. They offer projects for all year levels – from understanding our impact on the ocean, marine life and its importance in the eco-system to citizen science projects to get your students active and engaged in our environment through science.

Since 1986 Coral Cay Conservation has worked in 14 countries, on over 17 projects, and are internationally awarded for their achievements in environmental conservation.

The Coral Gardeners, based in Mo’orea in French Polynesia, aims to “change the world, one coral reef at a time”, via raising awareness and funds for reef restoration projects, using social media, merchandise and their Adopt a Super Coral programme. Their restoration work involves identifying super corals and growing super coral fragments until they are mature enough to be transplanted back onto the reef, with more than 15,000 corals have been replanted already. They are innovating new techniques using AI and smart sensors to observe and monitor the coral nurseries in real-time.

Coral Guardian is a French NGO which aims to protect coral reef ecosystems by engaging local communities and raising awareness among the general public. They have been working off Hatamin Island in Indonesia since 2015, and since late 2020, in Spain along with the nonprofit Coral Soul on the Deep CORE project to protect and restore coral ecosystems off the coast of Punta de la Mona (western Mediterranean).
