Summary
Abstract: 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.

Conductivity, temperature and depth (CTD) measurements were made at
various stations. Both Scripps Institution of Oceanography and Moss
Landing Marine Laboratory conducted the CTD measurements. Additional
parameters measured include salinity, oxygen concentration, potential
temperature, sigma theta (density), and beam attenuation. The
Endeavor cruise CTD data additionally features rescaled fluorescence
data (numerically equivalent to chlorophyll-a concentration).
