Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

Antarctic sea ice

A new study led by the University of Washington uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.

Key ocean fish can prevail with changes to farmed fish, livestock diets

forage fish swimming

Anchovies, herring, sardines and other forage fish play an essential role in the food web as prey for seabirds, marine mammals and larger fish like salmon. When ground into fishmeal and oil, they are also a key food source for farmed seafood and land-based livestock such as pigs and poultry. As seafood consumption outpaces the…
