资源简介：
The contributions of phytoplankton and bacteria cells to alkalinity (AT)
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 AT values measured
for unfiltered versus filtered samples to AT components contributed by
phytoplankton (retained on a 0.7 µm filter) and by phytoplankton and
bacteria combined (AT-BIO; retained on a 0.45 µm filter). The AT-BIO
values reached 10-19 μmol kg-1 in the East Sea and the North Pacific
Ocean, and progressively decreased to a level of 1 μmol kg-1 with distance
towards the Arctic Ocean. The study shows that the AT-BIO values are
non-negligible in coastal and open ocean environments and need to be
considered when assessing the accuracy of carbon parameters calculated
using the thermodynamic models that use measured AT as an input parameter.
