<p><b>Carbonate analysis methodology:</b> Calcium carbonate was determined from inorganic carbon measurements made on a Coulometrics Inc. Model 5011 CO<sub>2</sub> coulometer with a Model 5030 carbonate carbon apparatus. Between 5 and 10 mg of sample were acidified with 2ml 2N HCl to evolve CO<sub>2</sub>. The CO<sub>2</sub> gas was bubbled into a titration cell where CO<sub>2</sub> was converted to hydroxyethylcarbonic acid which was automatically titrated with a coulometrically-generated base to a colorimetric endpoint. Grams of carbon in the sample are calculated based on factory standardization of the coulometric titration. Calcium carbonate content was calculated by assuming that all inorganic carbon in the sample was present as calcium carbonate, a reasonable assumption for these biogenic sediments which contain little or no dolomite. The CO<sub>2</sub> coulometer has an accuracy of 0.15 &micro;g carbon. The precision of the complete procedure is &plusmn;0.52 wt% calcium carbonate based on the standard deviation of a lab standard of deep sea sediment which we developed from the study area. Duplicate analyses were performed on every tenth sample and an additional analysis was made for every pair which differed by more than 2 wt%.</p>

U.S. Joint Global Ocean Flux Study

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 Equatorial Pacific
http://usjgofs.whoi.edu/research/eqpac.html
U.S. JGOFS Equatorial Pacific
<p>The U.S. EqPac process study consisted of repeat meridional sections (12°N -12°S) across the equator in the central and eastern equatorial Pacific from 95°W to 170°W during 1992. The major scientific program was focused at 140° W consisting of two meridional surveys, two equatorial surveys, and a benthic survey aboard the R/V Thomas Thompson. Long-term deployments of current meter and sediment trap arrays augmented the survey cruises. NOAA conducted boreal spring and fall sections east and west of 140°W from the R/V Baldridge and R/V Discoverer. Meteorological and sea surface observations were obtained from NOAA's in place TOGA-TAO buoy network.</p>
<p>The scientific objectives of this study were to determine the fluxes of carbon and related elements, and the processes controlling these fluxes between the Equatorial Pacific euphotic zone and the atmosphere and deep ocean. A broad overview of the program at the 140°W site is given by Murray et al. (Oceanography, 5: 134-142, 1992). A full description of the Equatorial Pacific Process Study, including the international context and the scientific results, appears in a series of Deep-Sea Research Part II special volumes:</p>
