Gross and Net Oxygen Production Measured during the JGOFS North Atlantic Bloom Experiment (NABE)

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. In addition, JGOFS
hopes to improve global-scale predictions of the ocean's response to
human-inducded 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.

Net oxygen production was measured at various stations at several
depths in the photic zone. Values are in micromoles O2/liter/24hours.
In addition, for each station, net oxygen production integrated to the
1% light level is given.

Similarly, gross oxygen production (oxygen-18) was measured at various
stations at several depths in the photic zone. Values are in
micromoles O2/liter/14hours. Integrated gross oxygen production is
given for each station.
