Seasonal patterns in hydrography, oxygen, nutrients, particulate carbon and nitrogen and pigments were measured on monthly cruises at the Bermuda Atlantic Time-series Study site, 80 km southeast of Bermuda. Between October 1988 and September 1990, th

A field experiment, designed to evaluate several aspects of the microbially mediated organic carbon cycle, was conducted in the western basin of the Black Sea during May 1988. Measurements included standing stocks of particulate and dissolved carbon,

Sediment traps are the major oceanographic tool for collecting passively sinking particulate material (the “particle flux”) in the ocean. Sediment traps in the upper ocean also collect actively sinking zooplankton that are usually manually remove

Until the radiocarbon method for estimating primary production was developed by Steeman-Nielsen (1952), our understanding of global productivity distributions was, at best, rudimentary. Using this new technique, Steeman-Nielsen and Jensen (1957) coll
