Pelagic Diatom Fluxes I: Size Fractioned Time-Series Results from Subarctic Pacific Station PAPA during 1982-1983

摘要

A times series vertical flux assessment of pelagic diatoms was conducted during September, 1982 through September, 1983 at subarctic Pacific Station PAPA (50 deg N, 145 deg W; water depth 4200m) using PARFLUX sediment traps deployed at 1000 and 38000m. The time series sediment trap samples were collected for 11- to 16-day periods during the year; a total of 24 samples represent a full year's record of flux. Eighteen taxonomic groups of diatoms were enumerated, based on a census of four wet-sieved size fractions: 250-1000 micro m, 125-250 micro m, 63-125 micro m, and
