Warmer, saltier polar water could change global ocean currents

When ice shelves melt, they dump freshwater into the sea which lightens the salty water.

Melting ice shelves are changing the ocean’s chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change models. At the North and South Poles, cold dense water sinks, powering the so-called global ocean conveyor belt, … Read more

Raising ocean literacy levels could protect marine environment

Getting people involved in local community projects can help them engage with how the oceans are changing.

Hundreds of kilometres away from any sea, ocean or sandy beach, students from countries such as the Czech Republic have been discovering their connection with the marine world. While Europe’s landlocked states are understandably not so preoccupied with seas and oceans, camps run by members of Ecsite — the European network of science centres and museums — … Read more

Marine scientists steer trawlers away from sensitive sea floors

Newly developed trawling gear can lower the impact of fishing on the sea floor.

Bottom trawling, where fishing boats drag a heavy net along the seafloor, can devastate marine habitats and cause fish stocks to plummet, but scientists have developed new eco-friendly techniques to support the sustainability of an industry employing tens of thousands of people. Bottom (benthic) trawling indiscriminately catches bottom-feeder fish and seafood like plaice, cod, shrimp, … Read more
