Samples were collected using General Oceanics Inc. Nisken bottles deployed off a zodiac, tripped at the surface and at depths corresponding to 50, 30, 13, 4, and 0.5 percent of measured surface PAR. Samples were filtered onto GF/F filters and frozen at -60 degrees Celsius for a minimum of 24 hours. Pigments were then extracted in 90% acetone for 24 hours at -60 degrees Celsius. Samples were then injected onto a Waters C18 300mm column and separated by HPLC using a method adapted from Wright and Jeffrey, 1991. Peaks were identified by diode array spectrum analysis and integrated using Hitachi's D-7000 system; concentrations were calculated based on external standard curves in Microsoft Excel. Water sampled from Nisken bottles, which corresponded to light levels used in primary productivity simulated in situ experiments (see Sampling Frequency, above).
