The modeling effort will be in conjunction with analyses of these data sets as well as analyses of historical data sets from the two regions. The intent of the data analyses and modeling activities is to provide syntheses that allow comparison of similarities and differences in the two systems and thereby allowing fundamental questions on the controls of phytoplankton productivity and growth in these two systems to be addressed. Our general focus is on understanding the role of light, macro- and micronutrient limitation, and circulation in producing the observed horizontal and vertical gradients in phytoplankton distribution and production. Thus, the data analyses and model simulations will be used to test specific hypotheses concerning the regulation of phytoplankton growth, production, and species composition in the two regions.&lt;/p&gt; &lt;p&gt;This study will directly address several of the major Synthesis and Modeling Project research themes, especially those related to understanding processes controlling primary production and export production. Also, the incorporation data sets from another region of the Antarctic provides a mechanism for placing the observations obtained during the U.S. JGOFS Southern Ocean program into a broader context. This study will be the first to systematically compare and contrast regions of the Antarctic in this manner. We believe that the results of our collaborative research will have a significant impact on development of trophic level models within the Southern Ocean, and also have implications for ecosystem level studies in other regions of the world ocean.&lt;/p&gt; Methods and Sampling: Funding provided by National Science Foundation (NSF) Award Number: unknown SMP NSF completed Eileen E.

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).

The SMP deployment refers to the project being deployed.</p> <h3>INTRODUCTION</h3> <p>The Joint Global Ocean Flux Study (JGOFS) was an international scientific program devoted to the study of the ocean biogeochemistry of carbon and related elements and the linkages of the ocean with the global carbon cycle. The U.S. JGOFS program involved a decade long, intensive field effort that included: two on-going time-series stations off Hawaii and Bermuda; a series of process studies in the North Atlantic, Equatorial Pacific, Arabian Sea, and Southern Ocean; and a Global Ocean CO₂ Survey in conjunction with the World Ocean Circulation Experiment (WOCE). The resulting ocean biogeochemical data sets, together with satellite ocean color data from the NASA Sea-viewing Wide Field-of-view Sensor (SeaWiFS), formed a unique, long-term resource for the ocean community. With the completion of the field phase in the late 1990s, the U.S. JGOFS initiated a final Synthesis and Modeling Project (SMP), to build on and integrate these data sets in order to address the key scientific themes of JGOFS:</p> <ul> <li>determine the processes controlling the oceanic carbon cycle and ocean-atmosphere carbon fluxes</li> <li>develop improved capabilities for predicting future changes.</li> </ul> <p>Specifically, the central objective of the SMP was to synthesize knowledge gained from U.S. JGOFS and related studies into a set of models to reflect the current understanding of the ocean carbon cycle and its associated uncertainties (U.S. JGOFS, 1997). The SMP was tasked to address not only the processes that control carbon partitioning among oceanic reservoirs, but also the implications for ocean/atmosphere carbon exchange. Both data synthesis and modeling proposals were encouraged with an emphasis on coordinated interaction between the two. The major elements of the program included:</p> <ul> <li>Individual PI level projects</li> <li>Topical Working Groups</li> <li>Project management team (two co-coordinators and a project scientist)</li> <li>Data management (both distributed and centralized)</li> <li>Community activities (PI meetings, mini-workshops, special issues etc.).</li> </ul> <p>The SMP became a full fledged program with the funding of the first SMP awards in early 1998. Funding for SMP grants was provided by the National Science Foundation (NSF), the National Aeronautical and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and Department of Energy (DOE).</p> <h3>PROGRAM SCOPE</h3> <p>Specific projects within the SMP fell into two broad categories: data synthesis and extrapolation, and modeling. There was considerable (and necessary) overlap between the two, and the overview of the projects provided below is certainly a simplification of the collective efforts of the individual researchers (details on individual SMP grants can be found at <a href="http://usjgofs.whoi.edu/mzweb/syn-mod.htm">http://usjgofs.whoi.edu/mzweb/syn-mod.htm</a>). The scope and balance of the SMP was based on geographic region of study and investigation of biogeochemical processes.</p> <h3>Synthesis and Modeling Projects</h3> <p>The U.S. JGOFS SMP continued through the 2003-2004 time frame. As the program matured and specific initial projects were completed, the foci for the program was refined to emphasize both emerging new scientific directions and remaining unfinished elements of the original implementation plan. The SMP together with the U.S. JGOFS Steering Committee periodically assessed the program with regard to future priorities. During the active research phase, these are some of the topics identified as filling critical gaps for SMP science:</p> <ol> <li>synthesis of primary production, new production and export production (both particulate and dissolved)</li> <li>the mechanisms and rates of mid to deep water particle flux and remineralization as well as sediment diagenesis</li> <li>controls and distributions of calcium carbonate and silica production, transport and remineralization</li> <li>biogeochemical effects of trace metal cycling</li> <li>spatial and temporal extrapolation of biogeochemical flux estimates (e.g. export production) from local to basin and global scales</li> <li>development, evaluation and incorporation of mechanistically based, biological models for global carbon cycle simulations</li> <li>synthesis and modeling studies of the Arabian Sea, Southern Ocean, North Atlantic, ocean margins (with respect to the role of each in basin to global-scale carbon cycle), and the set of U.S. and international time-series stations data.</li> </ol> <p>At the local to regional scale, a series of data synthesis and food web modeling investigations explored aspects of euphotic zone production, recycling, export, transport and remineralization, and sediment cycling using the JGOFS process and time-series data base and related data sets. Individual projects concentrated, for example, on subsets of the overall JGOFS data (e.g. bacteria, mesozooplankton, HPLC pigments). Related projects focused on the distribution and dynamics of planktonic functional groups (e.g. N₂ fixers, diatoms, calcifiers). The eventual aim of many of these food web related studies was to extrapolate the findings to basin and global scale and/or to develop improved process-based parameterizations that could be incorporated into regional and global models.</p> <p>One or more regional ecosystem modeling studies were undertaken for each of the following U.S. process/time-series study locations: Equatorial Pacific and Atlantic, Arabian Sea, Ross Sea, Bermuda, and North Atlantic. Additionally, there were four projects which concentrated on data synthesis and/or modeling for various continental margins: NW Atlantic margin, southern Caribbean, Cariaco Basin, and several coastal upwelling regions. The regional synthesis and modeling studies as well as some of the food web projects relied heavily on satellite data. Many SMP projects utilized satellite data, in particular SeaWiFS ocean color, as an integral part of both model evaluation and time/space extrapolation.</p> <p>On the global perspective, over a dozen synthesis groups worked on the JGOFS/WOCE global CO₂ survey data with good coverage for all of the carbon related parameters (DIC, alkalinity, ¹³C, ¹⁴C, nutrients, oxygen, pCO₂, etc.). A coordinated global biogeochemical modeling effort was initiated as part of the international Ocean Carbon Model Intercomparison Project (OCMIP, <a href="http://www.ipsl.jussieu.fr/OCMIP/">http://www.ipsl.jussieu.fr/OCMIP/</a>). As the name implies, this was an observation-based evaluation of some thirteen global ocean biogeochemical models of the natural and anthropogenic inorganic carbon system, biogeochemical fields (nutrients, oxygen), and related passive chemical tracers (e.g. CFCs, ¹⁴C, ³He).</p> <h4>Links to Related Programs Subsequent to US JGOFS SMP:</h4> <p><a href="http://us-ocb.org/">Ocean Carbon &amp; Biogeochemistry (OCB)</a><br /> <a href="http://coastalcarbon.pbwiki.com/">North American Carbon Program (NACP) Coastal Synthesis</a><br />  </p> SMP largerWorkCitation project eng; USA oceans Global 2004-09-21 global oceans 0 BCO-DMO catalogue of parameters from Model results for the Ross Sea and West Antarctic Peninsula regions, 2004 (U.S. JGOFS Synthesis and Modeling Phase project results) Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact https://osprey.bco-dmo.org/dataset/3199/data/download download onLine asNeeded 7.x-1.1 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact Deployment: USJGOFS_SMP USJGOFS_SMP Institution laboratories laboratory USJGOFS_SMP http://usjgofs.whoi.edu/mzweb/smp/smpimp.htm Report describing USJGOFS_SMP Institution laboratories laboratory
