(min.), irradiance (%), depth (m), mgC/m^3/d, standard deviation of mgC/m^3/d Water was sampled at Palmer inshore stations B and E twice weekly and at Palmer inshore stations C and D once weekly. Samples were colleced using a Go-Flo bottle deployed off a zodiac, tripped at the surface and at depths corresponding to 55, 27, 11, 5, and 2 percent of measured PAR. Samples taken from Go-Flo bottles, 14C added, incubated 24h at corresponding light level on deck incubator and analyzed for inorganic carbon uptake. Samples from each light level were split into four 125ml incubation bottles and 5uCi 14C was added to each bottle. Two bottles were placed in an on deck incubator at corresponding light levels created with nickel plated screens. One bottle was placed in a four degree C refrigerator for a dark blank. Temperature was maintained in the incubator with running seawater. For time zero carbon uptake, 100ml water from the fourth bottle was filtered onto 25mm Whatman GF/F filters, and immediately acidified with 85:15 glacial acetic acid:methanol, dried for 24h at 60 degrees C, and read on a LSC. After 24h, the 3 treatment bottles were retreived from the incubators and analyzed as described above. Water sampled from Go-Flo bottles which corresponded to light levels simulated in on-deck incubators (see Sampling Frequency, above). lter, antarctic, carbon, primary productivity ASCII, comma separated DATA/9495PAL/PRPRODSIS 9495pal.prprodsis Maria Vernet Wendy Kozlowski Maria Vernet Wendy Kozlowski, Doug Ikelheimer, Karen Patterson, Ted Ruel, John Harrison Wendy Kozlowski, Ted Ruel Wendy Kozlowski, Ted Ruel Wendy Kozlowski Wendy Kozlowski 12/96 9/25/96 format only 9/25/97 Data was graphically reviewed.
