U.S. Joint Global Ocean Flux Study
http://usjgofs.whoi.edu/
U.S. Joint Global Ocean Flux Study
The United States Joint Global Ocean Flux Study was a national component of international JGOFS and an integral part of global climate change research.
The U.S. launched the Joint Global Ocean Flux Study (JGOFS) in the late 1980s to study the ocean carbon cycle. An ambitious goal was set to understand the controls on the concentrations and fluxes of carbon and associated nutrients in the ocean. A new field of ocean biogeochemistry emerged with an emphasis on quality measurements of carbon system parameters and interdisciplinary field studies of the biological, chemical and physical process which control the ocean carbon cycle. As we studied ocean biogeochemistry, we learned that our simple views of carbon uptake and transport were severely limited, and a new "wave" of ocean science was born. U.S. JGOFS has been supported primarily by the U.S. National Science Foundation in collaboration with the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the Department of Energy and the Office of Naval Research. U.S. JGOFS, ended in 2005 with the conclusion of the Synthesis and Modeling Project (SMP).

U.S. JGOFS Arabian Sea
<p>The U.S. Arabian Sea Expedition which began in September 1994 and ended in January 1996, had three major components: a U.S. JGOFS Process Study, supported by the National Science Foundation (NSF); Forced Upper Ocean Dynamics, an Office of Naval Research (ONR) initiative; and shipboard and aircraft measurements supported by the National Aeronautics and Space Administration (NASA). The Expedition consisted of 17 cruises aboard the R/V Thomas Thompson, year-long moored deployments of five instrumented surface buoys and five sediment-trap arrays, aircraft overflights and satellite observations. Of the seventeen ship cruises, six were allocated to repeat process survey cruises, four to SeaSoar mapping cruises, six to mooring and benthic work, and a single calibration cruise which was essentially conducted in transit to the Arabian Sea.</p>

<b>ship:</b> Thomas Thompson
<b>Note from R. Sambrotto:</b>
The data served as of August 12, 1997 have been modified in the
following ways from the data served prior to this date:
1) More particulate nitrogen, particulate carbon and nanomolar
ammonium data have been added that were not included with the
initial data release.
2) The uptake rates for nitrate, ammonium and urea needed to be
recomputed using the correct 15N isotope addition concentrations.

Methodology:
1. Ammonium - nanomolar ammonium concentrations, as measured by a
spectrophotometric procedure based on the Berthelot reaction followed
by an extraction step to concentrate the indophenol.

3. N-15 uptake -
A. Uptake rates for nitrate and urea were measured by incubation
experiments to follow the incorporation of trace additions of N-15
labeled substrate into particulate material collected by Whatman GF/F
filters.

B. Methodology for ammonium rates was similar to that for
nitrate and urea, except that modified isotope dilution model was used
to calculate uptake.
