Nitrogen-15 Uptake Rates Measured during the JGOFS North Atlantic Bloom Experiment (NABE)
Listed in NASA Earthdata CMR
The Joint Global Ocean Flux Study (JGOFS) seeks to understand the processes that control the transfer of carbon and other biologically active elements in the ocean.
Description
In addition, JGOFS hopes to improve global-scale predictions of the ocean's response to human-induced climate change. The North Atlantic Bloom Experiment (NABE) was a multidisciplinary, multinational pilot study of JGOFS, studying the spring phytoplankton bloom in the North Atlantic and its associated biogeochemical processes.
It took place from April until July, 1989, on two cruises of the RV Atlantis II and one cruise of the RV Endeavor. The stations in the North Atlantic were located from 18N to 72N and from 8W to 47W. At several stations, a water bottle rosette was used to collect water samples from various depths.

The water samples were analyzed for nitrogen-15 uptake rates from labeled substrates. The labeled substrates include nitrite, nitrate, ammonium and urea. The N-15 uptake rates from each labeled substrate are given in nanomolar/hr.
