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>

Methodology for POC and PON measurements
Water from the CTD rosette was transferred to brown polyethylene or
polycarbonate bottles and shielded from light until filtration (within
two hours of sampling). The bottles were rinsed with Milli-Q water
after each use and twice with sample before filling. The water was
then filtered through combusted (4 hours at 480°C) Whatman GF/F
filters at a pressure differential of <150 mm Hg. Typically, 2 liters
of sample were filtered for water collected in the upper 250 m and 4
liters were filtered for water collected below 250 m. The filters were
then stored at -80°C.
After the cruise, the filters were packed in dry ice and shipped to
Scripps Institution of Oceanography and stored at -80°C. The
filters were then dried at 60°C overnight in the presence of HCl
and then shipped to the Bermuda Biological Station for Research were
they were analyzed by BATS personnel using the BATS/JGOFS protocols.

<h2>Notes on the Sampling Methodology, by Hugh Ducklow</h2>
<pre>
Samples were harvested from hydrocasts into Milli-Q and sample-rinsed
2-liter polycarbonate bottles, and concentrated over low vacuum
filtration onto precombusted GF/F filters. Volumes collected were
adjusted according to depth, expected carbon concentration and filter
color (generally 1-4 liters). Filters were removed from the manifold
before they dried and were stored folded in half in plastic envelopes
in a dessicator. The filters were returned to the USA on dry ice, and
finally shipped to BBSR on dry ice for analysis.
Samples were analyzed at Bermuda Biological Station for Research
following the BATS protocols. <b> NB: Filters were acidified so the
carbon analysis is for particulate organic carbon not total particulate
carbon.</b>

Particulate organic carbon and nitrogen were collected from standard

filters, and stored for subsequent analysis following JGOFS
protocols. Samples were acidified, and represent organic
carbon. Samples were
analyzed at the Bermuda Biological Station for Research by BATS

In general the deep water (> 1000 m) values for C and N are greater
