This week the UK ran out of fish from her own waters, and became dependent on imported fish for the rest of the year, according to a report from NEF (the New Economics Foundation) and OCEAN2012.
Better news: the European Commission plans to phase out deep-sea bottom trawling and bottom gillnet fishing within two years in European waters, to help fish stocks recover.
A floating robot has been deployed to track great white sharks in the Pacific as part of efforts to understand the giant predators.
Researchers have found that an imbalance of nutrients in reef waters can increase the bleaching susceptibility of reef corals.
Researchers find elevated levels of caffeine pollution on Pacific Ocean shores.
Yellow brittle star could alter appearance and ecology of Atlantic coral reef habitats.
Large numbers of humpback whales are remaining in bays along the Western Antarctic Peninsula to feast on krill late into the austral autumn, long after their annual migrations to distant breeding grounds were believed to begin, according to a Duke University study.
Increased ultraviolet radiation has caused a sharp rise in the deaths of marine species, scientists have found.
Working in conjunction with the Marine Conservation Society (MCS), BSAC is inviting its clubs, divers and snorkellers to take part in a litter clean-up underwater.
Earth's oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased.
Nearly 1000 endangered green and hawksbill turtles have been released back into the waters of the Gulf of Thailand.
Plastic pollution off the northwest coast of North America is reaching the level of the notoriously polluted North Sea, according to a new study led by a researcher at the University of British Columbia.
For the first time, scientists have identified tropical and subtropical species of marine protozoa living in the Arctic Ocean. Apparently, they traveled thousands of miles on Atlantic currents and ended up above Norway with an unusual - but naturally cyclic - pulse of warm water, not as a direct result of overall warming climate, say the researchers. On the other hand: arctic waters are warming rapidly, and such pulses are predicted to grow as global climate change causes shifts in long-distance currents.
A diver has been airlifted to a decompression chamber after surfacing from a 91m (300ft) deep pool at a disused quarry in Snowdonia.
