Ocean Alliance, Inc. works to increase public awareness of the importance of whales and their marine environment, the oceans, through research and public education. 'We work with our scientific partners to collect a broad spectrum of data on whales and ocean life. Ocean Alliance uses this data to advise educators, policy makers, and the general public on wise stewardship of the oceans to mitigate pollution, prevent the collapse of marine mammal populations, and promote ocean and human health.' They have recently developed an innovative, less invasive method for attaching biologging tags on whales using drones, a product which goes by the name SnotBot - see their website and YouTube video for more information.

Initiated by Dutch teenager Boyan Slat in 2013, The Ocean Cleanup is designing and developing cleanup systems to clean up what is already polluting our oceans and to intercept plastic on its way to the ocean via rivers via their Interceptors. The Ocean Cleanup's team consists of more than 120 engineers, researchers, scientists and computational modelers working daily to rid the world's oceans of plastic.

Ocean Impact Alliance presents information about ocean-friendly initiatives that improve the ocean's ecosystems with the aim of achieving a sustainable society. They promote responsible entrepreneurship, in particular ocean-friendly investment proposals and projects. (No new posts since early 2020, possibly inactive?)

ORCA describes itself as a technology-based marine conservation association. Their strategy is to collect accurate and scientifically defensible data on water quality and its impact on marine ecosystems, to provide the data to the public and decision makers in an easily accessible and understandable format, and to engage communities in marine conservation action, with positive reinforcement for their efforts through feedback involving easily understandable scientific data. Focus of research is on the Indian River Lagoon.

Ocearch is conducting unprecedented research on sharks in order to help scientists collect previously unattainable data in the ocean. They achieve this through research expeditions, education and media. Their research expeditions are conducted aboard the M/V OCEARCH, which serves as an at-sea laboratory. Their OCEARCH GLOBAL SHARK TRACKER demonstrates the results of their tracking research on sharks (and some turtles). They have developed an OCEARCH STEM SKILLS curriculum for students, and use multimedia to inform and educate about shark science, in support of their goal to returning the ocean ‘balance and abundance’.

The Plastic Soup Foundation focuses on the impact of plastic on both life in the oceans and on human health, and with this in mind, they have dedicated campaigns on microplastics and plastic pollution. They have a strong educational drive, and they expose the problems, 'especially within the industry and the government!' (extract from their website). Their website has extensive information on the subject, with a solutions-oriented approach, and includes an app for tracking one's personal plastic footprint.

RanMarine Technology aims to ‘empower people and organizations across the planet to restore the marine environment to its natural state.’ They specialize in the design and development of industrial autonomous surface vessels (ASV’s) for ports, harbours and other marine and water environments. Their current products include the WasteShark™ range, which clears plastics, bio-waste and other debris from waterways. In the process. WasteShark collects data that enables close monitoring of the environment and makeup of their water. This creates an accurate picture of the water’s DNA to pinpoint any unquantified concerns. RanMarine products are designed to be used manually via an onshore operator, or autonomously with online control and access.

The Reef Ball Foundation is an international non-profit foundation whose mission is to rehabilitate and protect our world's ocean ecosystems through the development and use of ecologically sound-designed reefs and related systems. Their technology, Reef Balls, effectively create sustainable aquatic habitat and achieve it in a safe, long term, environmentally compatible way, by mimicking natural reefs. They are made with special concrete, with a pH similar to sea water, assures compatibility with marine environments and enhances its attractiveness to colonizing organisms.

Reef Design Lab designs coastal habitat infrastructure and artificial reefs. Working with international research partners, they develop techniques for enhancing the ecological performance of marine structures. Included amongst their projects are the award-winning Living Seawalls tiles, MARS 3D printed artificial reef structures and other artificial reef infrastructure, mangrove planters, fish habitat structures.

Reef Revive aims to save the ocean using 3D printed reefs to rebuild habitats for sea life. They are funding new artificial reef projects for thousands of species within U.S. waters. Using 3D printing technology, they are building underwater sanctuaries which create homes for ocean life and draws tourism away from natural coral reefs, giving them a chance to revive.

SINTEF Ocean aims at sustainable use of the ocean, as reflected in their statement that ‘Transport, food and energy production represent the backbone of ocean-based industries, and are also core areas for SINTEF Ocean. In addition, we focus on environmental technology, with one of the world’s leading professional environments in marine environmental technology’. Included in their extensive and impressive listing of projects are topics including marine litter and plastic pollution technology, aquaculture technology, marine vegetation cultivation, fishing nets technology and many more.

"Scaph Pro" association manages underwater maintenance and development programs involving artificial reefs in order to regenerate coral reefs, bringing together a multidisciplinary team made up of sea professionals, professional divers, scientists, oceanographers, archaeologists, photographers, architects etc. Photographs of their projects in the Philippines can be seen on their Facebook pages
