Water masses constrain the distribution of deep-sea sponges in the North Atlantic Ocean and Nordic Seas
Water masses are bodies of water with distinctive physical and biogeochemical properties. They impart vertical structure to the deep ocean, participate in circulation, and can be traced over great distances, potentially influencing the distributions of deep-sea fauna. The classic potential temperatu...
