Purified chlorophyll !!. purchased from Sigma Chemical Company (USA)
was used as the chlorophyll!!. source in calibration.
Resul ts
Station location, sampling dates, and cruise tracks for the eight
surveys are presented in Figures 1-9.
Concentrations of netplankton, nannoplankton, and total chlorophyll a
(mg/m3) as well as phaeopigment concentrations and acidification ratios
for each size fraction are presented in Table 2, according to sampling date
and consecutive station number. See Table 1 for summary of cruise dates.
