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 closed cooler for a dark uptake blank. Temperature was maintained in both "incubators" with running seawater. For time zero particulate 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. 2ml water from the fourth bottle was treated in the same manner for time zero total Carbon uptake. After 24h, the 3 treatment bottles were retrieved from the incubators and analyzed as described above. Water sampled from BOPS bottles which corresponded to light levels simulated in on-deck incubators (see Sampling Frequency, above). lter, antarctic, carbon, primary productivity ASCII, comma separated 97jan/prprodsis 97jan.prprodsis Maria Vernet Wendy Kozlowski Maria Vernet Wendy Kozlowski, Karie Sines, Joe Fontaine, Jeffrey Walker, Christine Braun Moraes, Danielle Harvey Wendy Kozlowski, Jeffrey Walker, Christine Braun Moraes Wendy Kozlowski Wendy Kozlowski Wendy Kozlowski 25 May 1999 Data was graphically reviewed.
