Basic Hydrographic, Nutrient, and Carbon/Nitrogen Chemistries 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-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.

Water bottles were used to collect water samples at various stations.
The water samples were analyzed for the following hydrographic,
nutrient and carbon/nitrogen parameters: temperature, potential
temperature, salinity, sigma-t (density), oxygen, nitrate, nitrite,
phosphate, silicate, ammonium, particulate organic carbon (POC),
particulate organic nitrogen (PON), total alkalinity, total carbon
dioxide, and partial pressure of carbon dioxide.

The following principal investigators were responsible for individual
sections of this merged data set:

Peter Brewer Total Alkalinity, Total Carbon Dioxide
Hugh Ducklow Particulate Organic Carbon and Nitrogen
James McCarthy Ammonium
Taro Takahashi Carbon Dioxide Chemistries
Robert Williams Temperature, Salinity, Nutrients
