Activities such as laying gas pipelines, trawling for fish, drilling for oil, and even burying internet cables in the deep sea, are destroying marine ecosystems. But studies have shown that reintroducing seaweed and corals to these habitats could ward off the worst effects – and recover marine life. Biodiversity loss is considered to be one … Read more

Noisier waters linked to behaviour change, hearing loss in whales

Studies investigating whale-watching boats and the inner ears of marine mammals could soon provide new insight into the effects of noisier oceans on cetaceans – dolphins, whales and porpoises – who depend on their hearing for navigating, finding food and communicating underwater. Noise in our oceans is increasing due to human activities such as shipping, … Read more

Sticky tape and simulations help assess microplastic risk

Microplastics are considered the most common form of marine litter.

by Natalie Grover Tiny pieces of plastic, now ubiquitous in the marine environment, have long been a cause of concern for their ability to absorb toxic substances and potentially penetrate the food chain. Now scientists are beginning to understand the level of threat posed to life, by gauging the extent of marine accumulation and tracking … Read more

Scientists explore underwater frontiers with submersible tablet computers

Technology for underwater use could change the way professional divers and researchers work.

A team of experienced science divers has created the world’s first submersible touchscreen for a tablet computer, whose applications are already helping marine scientists, law enforcement, explorers and other professionals toil beneath the waves and could usher in a new era of underwater ICT. It’s part of a new wave of subsea technology, which also … Read more

Europe must sea food in a new way thanks to warming waters

Aquaculture and fish farms must adapt to the changing sea conditions of climate change.

Aquaculture, or fish farming, is one of the world’s fastest growing food sectors, providing about half of all the fish we eat. As it stands, climate change is altering our ocean’s environment, causing the seawater to become warmer and impacting the marine  ecosystems profoundly. How will these changes affect marine species, consumers and industries that rely … Read more

Garbage-collecting aqua drones and jellyfish filters for cleaner oceans

It is estimated that more than 150 million tonnes of plastics have already accumulated in the world's oceans.

A Roomba-like ocean trash collector modelled on a whale shark and a microplastic filter made from jellyfish slime could prevent litter from entering our oceans and help tackle a growing problem that poses threats to wildlife, deters tourists and impacts on coastal economies. The cost of sea litter in the EU has been estimated at up to … Read more
