A time series vertical flux assessment of pelagic diatoms was
conducted during September, 1982 through September, 1983 at subarctic
Pacific Station PAPA (50°N, 145°W; water depth 4200 m) using PARFLUX
sediment traps deployed at 1000 and 38000 m. 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: 250-1000μm, 125-250μm, 63-125μm, and 〈 63μm.
In order to study the sinking processes of diatoms, detailed information
on frustule integrity was acquired. For example , counts of single valves
were separated from frustules. Size-fractioned fluxes of all the
counting groups are graphically presented, which provides a data base for
further investigations.
