Greenovation Hub (GHub) is ‘an independent environmental think tank with a global outlook, registered with the Beijing Municipal Civil Affairs Bureau.’ They work to promote sound climate and environmentally friendly policies through research, advocacy, negotiations, education and dialogue. One of their projects is focused on Ocean Conservation, which has as its aim that China leads the conservation of high seas biodiversity and plays a leading role in global ocean governance and collaboration. To achieve this, GHub works in China ‘to advance sustainable fishery and catalyze the building and effective management of science-based and representative marine protected areas (MPAs) by engaging experts in science, policy, law, business, academia and communications.’

Founded in June 2019, Guardians of the Deep runs Environmental Education Programmes for children which include the Guardians Curriculum and the Chacma Champions Holiday Programme. Through MasiCORP, they are running the Guardians of the Deep curriculum for students from Ukhanyo Primary and Masiphumelele High schools, and are now also offering the curriculum at Kleinberg Primary School in Ocean View. Partnering with Surf Outreach in Muizenberg, they introduced the world beneath the waves to the surfers that ride them. Blending science, art and storytelling, the students are empowered to explore the ocean from its multi-coloured rock pools to its darkest depths while learning about the lives of the uniquely awesome creatures making it their home. Through this exploration and discovery, students realise the importance of the environment and how our choices are key in bringing about the change much-needed to conserve the natural world.

Their programme of community based research and education encourages strong local stewardship and supports meaningful change for the conservation of Hebridean cetaceans and marine life.

The Hellenic Centre for Marine Research is a governmental research organisation operating under the supervision of the General Secretariat for Research and Innovation (GSRI). It comprises three institutes: the Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC), the Institute of Marine Biological Resources and Inland Waters (IMBRIW) and the Institute of Oceanography (IO). Its main areas of research include physical oceanography, marine geology, marine biology, fisheries, aquaculture, marine genetics, and inland waters. It also provides consulting services, offers educational programs and courses, and participates in international research projects. The two international standard aquaria and Hydrobiological Station of Rhodes, operating under the HCMR umbrella, aim to stimulate interest in, to develop and to spread knowledge about the marine environment mainly focusing in the Eastern Mediterranean area

HKDCS is the only conservation society dedicated to whales, dolphins and porpoises (cetaceans) of Hong Kong. Their work focuses around the Indo-Pacific humpback dolphin (known as Chinese white dolphin and pink dolphin) and Indo-Pacific finless porpoise. The numbers of these species are dropping rapidly, especially the humpback dolphins, from 250 in the 1990's, to 100 in 2009 to 32 in 2018. HKDCS promotes public awareness, preservation of habitats, raising standards of Hong Kong's whale watching activities and conducts research. They are involved in opposing reclamation projects such as for the airport third runway, bridges and large-scale artificial islands which destroy the habitat of dolphins and porpoises.

The I AM WATER Ocean Guardians Program aims to build an understanding of the interdependence of healthy humans and healthy oceans and to influence behaviours to protect our global seas. The programme is aimed at low-income children who live near the sea in South Africa.

InPact was established in 2020 by researchers in the environmental and sustainability areas. They aim to contribute to the conscious use of natural resources, based on research supported by actions aimed at sustainable practices, environmental preservation and conservation, with the engagement of traditional communities and society as a whole. This includes the rescue, rehabilitation and reintroduction to the natural environment of marine and aquatic animals. They also carry out environmental education activities; monitoring of coral reefs; research into sediment analysis through granulometric analysis, organic matter and carbonate contents; identification and monitoring of macrobenthic species and reef fish, and analysis of the physical and chemical parameters of the water.

Indo Ocean Project is a marine research and conservation program in Indonesia. As a field research station located in Nusa Pineda, they have a strong education component, training dive professionals through a conservation-dive master internship program. Their field expeditions host international and local research projects on marine conservation efforts including marine megafauna, coral restoration, ecological monitoring, community outreach and education programs. Projects are at Nusa Penida in Bali, and in Tanjung Bira, South Sulawesi. They also have liveaboard expeditions.

Based on Lombok Island, IBF is an independent foundation that works on educating society through practical scientific research findings to empower the local community while restoring the marine ecosystem. They focus on coral reef research, restoration, and coastal communities development. While their main approach is science, with the aim to increase the marine literacy of Indonesian citizens, they also work together with a lot of local communities to integrate scientific findings for practical use in the field.
