The Role of Ecosystem Dynamics on the Global Ocean Carbon Cycle: A JGOFS Model-Data Synthesis. Dataset Description: <p>We propose to better quantify the role of marine
ecosystem dynamics on the global ocean carbon cycle, focusing in particular
on air-sea CO2 exchange, net community production, and vertical export.
The research is motivated by two related hypotheses:&nbsp;
<ul>
<li>
multi-nutrient limitation (N, P, Si, Fe) modulates phytoplankton biomass
and primary production, community structure,and biogenic carbon export,&nbsp;</li>
<li>
community structure governs the elemental composition of the exported dissolved
and particulate material, major determinants of subsurface biogeochemical
transport, remineralization, and sequestration.&nbsp;</li>
</ul></p>
<p><br>To this purpose, we will conduct a carefully designed set of numerical
experiments in a global 3-D coupled ecological-biogeochemical-physical
model. The project directly builds upon our recent progress and specific
findings/questions from a global mixed layer ecosystem model that includes
explicit iron limitation and community structure, a full depth 3-D ocean
carbon cycle model, and historical hind-cast simulations (1958-1997) of
ocean physical circulation. Specifically, funding is requested to:&nbsp;
<ul>
<li>
Complete development of a next generation, global 3-D ecological-biogeochemical-physical
model that includes multi-nutrient limitation and explicit geochemical
functional groups (picoplankton, diatoms, Trichodesmium, and coccolithophores).&nbsp;</li>
<li>
Evaluate and iteratively imporve on the simulated uper ocean ecosystem
dynamcs against regional JGOFS data sets, large-scale surface pCO2 and
nutrient fields, and satellite ocean color data using retrospective, historical
simulations for the period 1988-2000.&nbsp;</li>
<li>
Assess the skill of the resulting model in replicating the full depth,
equilibrium distributions of carbon, oxygen and nutreints against the WOCE/JGOFS
global survey data. Test the ecological and biogeochemical impact of dust
deposition, calcification, nitrogen fixation, and silica production by
selective modifications to the base coupled solution.&nbsp;</li>
</ul>
The study directly addresses the overall goal of the U.S. JGOFS Synthesis
and Modeling Project (SMP), to synthesize present knowledge into global
numerical models that can be used for prediction, as well as two of the
major research trajectories highlighted in the SMP program announcement:
"global and regional studies that link together the biological, physical,
and chemical components of the marine carbon cycle" and "synthesis and
modeling efforts that effectively combine field data sets and diagnostic
and prognostic (forward) models".</p> Methods and Sampling:

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 Synthesis and Modeling

<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 CO<sub>2</sub> 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. N<sub>2</sub> 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 CO<sub>2</sub> survey data with good coverage for all of the carbon related parameters (DIC, alkalinity, <sup>13</sup>C, <sup>14</sup>C, nutrients, oxygen, pCO<sub>2</sub>, 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, <sup>14</sup>C, <sup>3</sup>He).</p>
