Can These 6 Marine Tech Startups Help Solve The Many Issues Facing Our Oceans?

4 Mins Read

Some of the most exciting young “ocean innovators” accepted into UpLink, the open digital platform launched by the World Economic Forum (WEF), are working toward sustainable progress in ocean conservation. 

Life below water is a vital planetary resource that we depend on for everything from absorbing nearly a third of carbon dioxide produced by humans, to supporting the very coastal ecosystems that act as buffers against natural disasters and providing livelihoods for over three billion people in the world.

But thanks to human activities that degrade the natural environment, plastic pollution, ocean acidification and marine biodiversity loss has reached alarming levels.

Now, startup companies and nonprofit organisations are coming up with solutions in a bid to reverse some of the damage we’ve done and developing innovative ways to protect our oceans and their living inhabitants. 

Arc Marine

1. Arc Marine 

Founding date: 2015

Founders: Tom Birbeck & James Doddrell

Headquarters: Devon, United Kingdom

Arc Marine has designed innovative “reef cubes” that can help boost large-scale coral restoration projects. Their patented solution enables the creation of reef structures anywhere in the world, allowing “anyone from scientists to remote fishers can contribute to rebuilding reef systems”. 



Founding date: 2019

Founder: Stephen Rodan

Headquarters: Washington D.C., United States

CHARM is a coral farming robot developed using scientific research and computer automation to help reduce costs and save time to grow large-scale coral colonies. It has been created by the partnering nonprofits Beyond Coral Foundation, based in the U.S., and Beyond Coral México, who have made it their mission to protect coastal ecosystems. 

Plant A Million Corals

3. Plant A Million Corals

Founding date: 2019

Founder: David Vaughan

Headquarters: Summerland Key, Florida, United States

Plant A Million Corals has come up with cost-efficient and adaptable coral restoration units that can be deployed to support coral growth and also empower communities to participate actively in protecting life under water. Using micro-fragmentation processes, the planting projects allow for rapid coral growth and healing at rates that are around 25 to 40-times faster than they would naturally occur, making it possible to save and recover lost reefs. 

Cascadia Seaweed

4. Cascadia Seaweed

Founding date: 2019

Founders: William T. Collins, Mike Williamson, Tony Ethier

Headquarters: Sidney, British Columbia, Canada

Cascadia Seaweed recently shifted its strategic direction from being an ingredients supplier to a human food producer, manufacturing delicious and sustainable plant-based food products out of seaweed. Their goal is to provide nutritious vegan foods while promoting climate action, ocean regeneration and economic resiliency for Indigenous communities through seaweed cultivation. 

SharkSafe Barrier

5. SharkSafe Barrier

Founding date: 2014

Founders: Michael Rutzen, Sara Andreotti, Conrad Matthee, Anita Nel, Laurie Barwell

Headquarters: Stellenbosch, Western Cape, South Africa

SharkSafe Barrier is a solution that successfully biomimics the visual look of a kelp forest, combining it with permanent magnetic stimuli to form an eco-friendly barrier that deters shark species from passing through in order to protect humans from sharks without harming our precious marine life.

Australian Seaweed Institute

6. Australian Seaweed Institute

Founding date: 2018

Founder: Jo Kelly

Headquarters: Teneriffe, Queensland, Australia

The Australian Seaweed Institute is developing a seaweed biofilter technology to conserve the Great Barrier Reef. They have come up with a network of seaweed biofilters that can be harvested for applications in a variety of products such as biofertiliser, and hope that they can drive a sustainable and climate-positive seaweed industry in Australia.
