Primary production and chlorophyll a in the northwestern Pacific Ocean in summer

Primary production was measured in the Western Subarctic Gyre (WSG) and adjacent regions in July 1993 and 1994. The primary production integrated from the surface to the 2% light depth (16-40 m) ranged from 255 to 1198 mg C m super(-2) d super(-1) in the WSG. Mean plus or minus standard error (SE) o...

Description
Summary:Primary production was measured in the Western Subarctic Gyre (WSG) and adjacent regions in July 1993 and 1994. The primary production integrated from the surface to the 2% light depth (16-40 m) ranged from 255 to 1198 mg C m super(-2) d super(-1) in the WSG. Mean plus or minus standard error (SE) of the primary production was estimated to be 663 plus or minus 86 mg C m super(-2) d super(-1) (n = 11) in both years. Chlorophyll a (chl) concentration in the upper 2% light depth ranged from 0.32 to 6.95 mu g L super(-1), and the mean plus or minus SE was calculated to be 1.03 plus or minus 0.15 mu g L super(-1) (n = 44). The mean plus or minus SE of chl standing stock integrated in the upper 2% light depth was calculated to be 28.6 plus or minus 2.9 mg m super(-2) (n = 11).
