Conductivity, Temperature and Depth (CTD) Measurements Made 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-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).
