When CO₂ enters the ocean, where does this heat-trapping gas go? By Madeline Drexler When heat-trapping carbon dioxide from the atmosphere sinks into the ocean and turns to organic carbon, how much of it sinks to the deep ocean and how quickly? Ken Buesseler, a geochemist at Woods Hole Oceanographic Institution (WHOI), has been working…

Antarctic Krill—the Unsung Heroes of Climate Mitigation in the Southern Ocean

Antarctic krill—and more importantly, krill poop—are an important part of the global climate system. Unlike many species that migrate miles across the surface, krill migrate vertically, depositing their carbon-filled waste deep below the surface. This helps mitigate climate change, but they’re under threat from capture for use as fishmeal to feed aquaculture operations or oils…
