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>

<h2>Herbivory Methodology</h2>
Microzooplankton grazing on phytoplankton, herbivory, was measured
using the dilution technique (1) as modified by Landry et al (2). The
modifications of this method provide a means of determining
microzooplankton grazing rates of phytoplankton as well as
phytoplankton growth rates. Experiments were performed on shallow
(5-10m) and deep (35-80m) water samples at the "long" stations. Water
was collected in 30L GoFlo bottles on the trace metal clean rosette.
Filtrate (<0.2um) for the dilutions was prepared for each depth using
Gelman 0.2 um cartridge filters which had been presoaked in acid to
remove dissolved organic material. DOC analyses (courtesy of Dennis
Hansell, BBSR) and nutrient analyses (courtesy of Kathy Kogslund, UW)
indicated no measurable changes in nutrient concentrations or DOC due
to the filtration process. Incubations for 24 hrs. were conducted in 1
liter polycarbonate bottles which were placed in light attenuated
flowing seawater on-deck incubators.
Bottles used for grazing rate determinations were enriched with
nutrients (10 uM ammonium chloride, 1 uM sodium phosphate and 10 uM of
carbon as glucose). Samples were filtered onto 25mm GF/F filters and
extracted for 24 hrs. at 4 degrees C in 7ml of 100% acetone. After
extraction the filter was removed and the sample read in a fluorometer
(Turner Designs) calibrated against chlorophyll a. Net phytoplankton
growth rates were determined from the change in chlorophyll a
concentration in the unenriched whole seawater bottles over the length
of the incubation. Grazing rates on phytoplankton were calculated from
the regression relationship between the apparent phytoplankton growth
rates (change in chloropyll concentration) in the nutrient enriched
treatments and the fraction of unfiltered seawater in the various
treatments.
