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).

http://usjgofs.whoi.edu/research/arabian.html
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>

<h1>Standing Stocks and Microzooplankton Grazing Rates in the Equatorial Pacific</h1>
<p><strong>Michael R. Landry</strong></p>
<hr />
<p><strong>Standing Stocks (Transect Cruises):</strong></p>
<p>Samples will be taken from predawn hydrocasts at each station. Population abundances of bacteria, cyanobacteria (<em> Synechococcus</em> and <em> Prochlorococcus</em>), and chlorophyll-containing nanoplankton will be determined from preserved samples frozen in liquid N and analyzed by flow cytometry (FCM) with internal standards of fluorescent beads. Biomass of nanoplankton will be estimated from calibrated relationships between forward and right-angle light scatter and carbon of cultured phytoplankton. The size structure of pico-plankton will be measured directly (shipboard) on unpreserved samples with a Coulter N4MD submicron particle analyzer. Slides for population and biomass assessment by epifluorescence image analysis will be prepared by us and analyzed by Sieracki <em> et al.</em>; thus constituting an intercomparison of methods. Larger volume samples for rare phytoplankton (e.g., large diatoms and dinoflagellates) and ciliated protozoa will be preserved by us for later microscopical analysis by Sieracki <em> et al.</em></p>
<p><strong>Microzooplankton Grazing Rates:</strong></p>
<p>Phytoplankton growth and microzooplankton grazing rates will be estimated for three depth strata (mixed layer mid-euphotic zone, and chlorophyll max) using the dilution assay with fluorescently-labelled prey as an internal standard for relative grazing rates. Rate estimates will be derived from total chlorophyll (fluorometry) and various populations of phytoplankton determination by HPLC pigments (R. Bidigare) and FCM. We will run these experiments at each station on the transect cruises; Sieracki <em> et al.</em> will run dilution experiments on the time-series cruises.</p>
<p>Short-term experiments involving uptake of fluorescently-labelled prey, bacteria (FLB) and algae (FLA), will be run at each station to assess grazing rates of different taxa, size-selection by grazers, and the occurrence and rates of algal mixotrophy. FLB-uptake experiments will be run in conjunction with <img src="https://datadocs.bco-dmo.org/static/usjgofs.whoi.edu/smallgifs/tiny_3.gif" />H-thymidine work by D.L. Kirchman and H.W. Ducklow to test the assumption that grazing balances growth rate. Rates will be estimated from the time-course (30--60 min.) of particle uptake by microzooplankton as determined by FCM and epifluorescence microscopy (slides) using formalin-killed samples as controls.</p>
<p>Growth and grazing mortalities of heterotrophic and photosynthetic bacterial populations will be independently determined from differences in the rates of change of populations (determined by FCM analysis) in 24-h incubations with and without the prokaryotic inhibitor ampicillin. FLBs will be used as internal controls. Parallel, long-term incubations will also measure the rate of decline of FLAs and will constitute an independent rate estimate of microzooplankton grazing on algae in the nanoplankton size range.</p>
