Contribution of Marine Phytoplankton and Bacteria to Alkalinity: An Uncharacterized Component
The contributions of phytoplankton and bacteria cells to alkalinity (A(T)) were measured in seawater samples obtained from 205 locations including the East Sea, the North Pacific Ocean, the Bering Sea, the Chukchi Sea, and the Arctic Ocean. We attributed the differences in A(T) values measured for u...
