Biogenic Particle Fluxes at the 34 deg N 21 deg W and 48 deg N 21 deg W Stations,1989-1990: Methods and Analytical Data Compilation

摘要

This technical report represents the results of analyses on opal, organic carbon,nitrogen and phosphorus content in each of 156 specimen samples collected from the moored sediment trap experiment that was a part of JGOFS North Atlantic Bloom Experiment. The analyzed samples represent a spacio-temporal matrix formed by 6 time-series sediment traps that provided 26 periods of uniform and synchronized periods of 14 days. Traps were deployed at 3 depths, 1 km, 2 km and 0.7 km above the bottom, and at 2 stations, 34 deg N 21 deg W and 48 deg N 21 deg W from April 4, 1989 to April 17, 1990, as shown in Tables 1 and 2. Two of the periods were not 14 days, and there was an 18-day hiatus in September/October 1989 for changeover of the trap moorings. Some samples were unusable because of the intrusion of fish. Samples were separated into several aliquots by wet-splitting,
