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 refrigerator for a dark uptake blank. Temperature was maintained in the deck incubator with running seawater. For time zero particulate Carbon uptake, 100ml water from the fourth bottle was filtered onto 25mm Whatman GF/F filters, immediately acidified with 20% hydrochloric acid, allowed to offgas for 12 hours, and read on a LSC. After 24h, the 3 treatment bottles were retrieved 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).
