Chlorophyll-a and phaeopigments, water column observations, Apr-Sept 2001-02, Continental Margin Western Antarctic Peninsula, GLOBEC.

Water for chlorophyll-a and phaeopigment concentrations
was collected using a CTD Niskin rosette sampler during 4
cruises to the Antarctic, April-September 2001 and 2002. In addition
to the water column sampling, ancillary sampling of the surface
waters, ice cores, and ice related observations are reported. The
general survey area includes: the continental shelf to the west of the
Antarctic Peninsula extending from the northern tip of Adelaide Island
to the southern portion of Alexander Island, Marguerite Bay, and
seaward to depths of 3000 meters.

Chlorophylls were measured using a Turner Designs Digital 10-AU-05
Fluorometer, calibrated using a chlorophyll a standard from Sigma
Chemicals, dissolved in 90% acetone.

Data reported: chlorophyll-a and phaeopigment concentrations
