Figure 5.1. Polycystine fluxes vs. mean annual chlorophyll a. Polycystine flux data are the same as those in Figure 4; chlorophyll data are mean annual values at 10 m depth (from Conkright et al. 1998a, b, c). 5.2. Polycystine production half-time (i.e., the time it takes to generate 50, 75 and 90% of the overall radiolarian flux during the entire trapping period when chronological flux data are sorted in descending order; as a percentage of overall trapping time) as a function of latitude. Based on 44 sediment trap moorings deployed for at least 300 consecutive days.
