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 outside 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 20% hydrochloric acid, allowed to off-gas for 24h, 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 Go-Flo bottles, which corresponded to light levels simulated in on-deck incubators (see Sampling Frequency, above).
