Fish carcasses deliver toxic mercury pollution to the deepest parts of the ocean

A new study into deep-sea fish and crustaceans has revealed the presence of anthropogenic mercury pollution at the deepest points in the ocean, including the Marianna Trench. Researchers suggest that the most likely source of the toxic chemical is the sinking bodies of dead fish from the surface. Mercury pollution in the ocean is an … More Fish carcasses deliver toxic mercury pollution to the deepest parts of the ocean

Oceans becoming more stratified due to global warming

A worrying new study, by a group of international researchers from China and the US, has found that our oceans are becoming more layered and resistant to vertical mixing, due to increased warming at the surface from climate change. In the ocean, stratification occurs between water with different physical properties, such as temperature, salinity and … More Oceans becoming more stratified due to global warming

Algae & the asteroid: how single-celled plankton succeeded where the dinosaurs failed

New research has revealed how photosynthetic algae managed to survive the asteroid that killed the dinosaurs, by quickly adapting to hunt other microbes in the absence of sunlight. Not only did this help them thrive when so many species were wiped out, but it also provided a much needed lifeline to our early oceans. Around … More Algae & the asteroid: how single-celled plankton succeeded where the dinosaurs failed
