How 6 robots are helping to protect our oceans

• Oceans are critical to life on Earth, but they are coming under enormous environmental pressure.
• The World Economic Forum’s Friends of Ocean Action group says it’s not too late to help them recover.
• Here’s how robots are playing their part in protecting the marine environment.

Oceans cover almost three-quarters of the Earth’s surface and contain 80% of its biodiversity. Life would be impossible without them, yet they are under threat as never before. But robot technology is helping protect them for the future.

As well as absorbing almost a third of our carbon emissions, oceans have also soaked up 90% of the additional heat that human-generated global warming has created.

The Friends of Ocean Action, a group of global leaders convened by the World Economic Forum, says it’s not too late to save the seas. “We have the knowledge, power and technology to put the ocean on a path to recovery,” the group says. “The ocean’s power of regeneration is remarkable, if we just offer it the chance.”

What’s the World Economic Forum doing about the ocean?

Our ocean covers 70% of the world’s surface and accounts for 80% of the planet’s biodiversity. We can’t have a healthy future without a healthy ocean – but it’s more vulnerable than ever because of climate change and pollution.

Tackling the grave threats to our ocean means working with leaders across sectors, from business to government to academia.

The World Economic Forum, in collaboration with the World Resources Institute, convenes the Friends of Ocean Action, a coalition of leaders working together to protect the seas. From a programme with the Indonesian government to cut plastic waste entering the sea to a global plan to track illegal fishing, the Friends are pushing for new solutions.

Climate change is an inextricable part of the threat to our oceans, with rising temperatures and acidification disrupting fragile ecosystems. The Forum runs a number of initiatives to support the shift to a low-carbon economy, including hosting the Alliance of CEO Climate Leaders, who have cut emissions in their companies by 9%.

Technology has a key role to play in saving our seas, and the six solutions featured here harness the power of robotics to do so. Many are members of the Ocean community on the Forum’s Uplink innovation crowdsourcing platform.

1. Mapping the seafloor

German company Planblue is creating a highly detailed map of the ocean floor using a robotic “underwater satellite” that relies on artificial intelligence (AI) and machine learning to navigate.

Around 80% of the ocean floor is unmapped and unexplored. Planblue’s advanced imaging will provide a clear picture of the impact of climate change, biodiversity loss and pollution in the oceans. Helping identify problems is the first step to identifying solutions.

2. Protecting whales

As many as 30,000 whales are killed or injured every year in collisions with ships, according to the World Cetacean Alliance. The largest and most endangered species are most at risk, but technology is coming to their aid.

In California, Whale Safe uses an acoustic buoy to listen for whales and transmit a warning to ships to slow down. It has already cut the number of whale collisions in the busy shipping lane leading to the port of Los Angeles.

Canadian company Whale Seeker uses AI to automate aerial and infrared imagery to detect the presence of sea mammals. As well as preventing collisions, it can monitor the activities of whale populations over wide areas.

3. Monitoring marine health

Underwater drone Hydrus, designed by Australian innovators Advanced Navigation, is capable of diving 3,000 metres below the ocean surface. Equipped with powerful lights and able to operate completely autonomously, it can locate and identify new marine species.

Hydrus can also monitor the health of coral reefs and will help plug serious gaps in our knowledge about ocean life, giving decision-makers new insights into how to protect and conserve ocean ecosystems. And all in a package that weighs less than 7 kilograms.

Just like the authorities on dry land, ocean conservationists need to know who and what lives where. There are estimated to be 2.2 million marine species, but only 10% of them have been discovered and named. Now scientists are going looking for the rest.

Using remote underwater robots, Ocean Census will seek out new species with a goal of discovering 100,000 new creatures within a decade. High-resolution imaging and lasers will be supplemented by technology that can sequence DNA shed into the ocean by its inhabitants.

5. Creating an underwater internet to aid exploration

The internet of things is increasingly commonplace on dry land. But can we do the same thing underwater? Italian firm WSense has a solution.

Using patented acoustic and optical technologies, it enables submerged devices and remote sensors to network and share data, solving what has been a major problem in ocean monitoring. As well as environmental benefits, it also has aquaculture, energy, security and defence applications.

6. Genetic ocean health check

The oceans are full of DNA. It’s shed by living creatures and it’s known as environmental DNA, or eDNA. A team at Monterey Bay Aquarium Research Institute (MBARI) in California is using long-range autonomous robot submarines to collect eDNA and monitor ocean health.

“This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species, and the spread of invasive species – all critical to understanding, promoting and maintaining a healthy ocean,” the MBARI team says.
