E Remarkable heterogeneity in meso- and bathypelagic bacterioplankton
We investigated meso- to bathypelagic (500–3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Ocean near the Hawaiian archipelago, at the San Pedro Ocean Time Series (SPOTS) station off southern C...
