Bottom trawling for fish like sole and crustaceans and dredging to maintain harbors disrupts the seafloor, causing a cascade of chemical changes that reduce the ocean’s ability to sop up climate ...

But to date, only about 25% of it has been surveyed in this way. To produce a global picture of the seafloor, researchers have relied on satellite data. More accurate maps of the ocean floor are ...

This reduction, mostly resulting from a global slowdown in seafloor spreading, caused ocean basins to deepen. In the new work ...

In 2013, I was conducting experiments to measure seafloor carbon cycling in the Clarion-Clipperton zone of the Pacific Ocean in 2013. I deployed a lander system (a remote-operated platform used to ...
