    • Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms 

      Orr, James C.; Fabry, Victoria J.; Aumont, Olivier; Bopp, Laurent; Doney, Scott C.; Feely, Richard A.; Gnanadesikan, Anand; Gruber, Nicolas; Ishida, Akio; Joos, Fortunat; Key, Robert M.; Lindsay, Keith; Maier-Reimer, Ernst; Matear, Richard J.; Monfray, Patrick; Mouchet, Anne; Najjar, Raymond G.; Plattner, Gian-Kasper; Rodgers, Keith B.; Sabine, Christopher L.; Sarmiento, Jorge L.; Schlitzer, Reiner; Slater, Richard D.; Totterdell, Ian J.; Weirig, Marie-France; Yamanaka, Yasuhiro; Yool, Andrew (2005-07-29)
      The surface ocean is everywhere saturated with respect to calcium carbonate (CaCO3). Yet increasing atmospheric CO2 reduces ocean pH and carbonate ion concentrations [CO32−] and thus the level of saturation. Reduced ...
    • Evaluating global ocean carbon models : the importance of realistic physics 

      Doney, Scott C.; Lindsay, Keith; Caldeira, Ken; Campin, J.-M.; Drange, Helge; Dutay, J.-C.; Follows, Michael J.; Gao, Y.; Gnanadesikan, Anand; Gruber, Nicolas; Ishida, Akio; Joos, Fortunat; Madec, G.; Maier-Reimer, Ernst; Marshall, John C.; Matear, Richard J.; Monfray, Patrick; Mouchet, Anne; Najjar, Raymond G.; Orr, James C.; Plattner, Gian-Kasper; Sarmiento, Jorge L.; Schlitzer, Reiner; Slater, Richard D.; Totterdell, Ian J.; Weirig, Marie-France; Yamanaka, Yasuhiro; Yool, Andrew (American Geophysical Union, 2004-09-15)
      A suite of standard ocean hydrographic and circulation metrics are applied to the equilibrium physical solutions from 13 global carbon models participating in phase 2 of the Ocean Carbon-cycle Model Intercomparison Project ...
    • Evaluation of ocean carbon cycle models with data-based metrics 

      Matsumoto, K.; Sarmiento, Jorge L.; Key, Robert M.; Aumont, Olivier; Bullister, John L.; Caldeira, Ken; Campin, J.-M.; Doney, Scott C.; Drange, Helge; Dutay, J.-C.; Follows, Michael J.; Gao, Y.; Gnanadesikan, Anand; Gruber, Nicolas; Ishida, Akio; Joos, Fortunat; Lindsay, Keith; Maier-Reimer, Ernst; Marshall, John C.; Matear, Richard J.; Monfray, Patrick; Mouchet, Anne; Najjar, Raymond G.; Plattner, Gian-Kasper; Schlitzer, Reiner; Slater, Richard D.; Swathi, P. S.; Totterdell, Ian J.; Weirig, Marie-France; Yamanaka, Yasuhiro; Yool, Andrew; Orr, James C. (American Geophysical Union, 2004-04-02)
      New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative ...
    • Impact of circulation on export production, dissolved organic matter, and dissolved oxygen in the ocean : results from Phase II of the Ocean Carbon-cycle Model Intercomparison Project (OCMIP-2) 

      Najjar, Raymond G.; Jin, X.; Louanchi, F.; Aumont, Olivier; Caldeira, Ken; Doney, Scott C.; Dutay, J.-C.; Follows, Michael J.; Gruber, Nicolas; Joos, Fortunat; Lindsay, Keith; Maier-Reimer, Ernst; Matear, Richard J.; Matsumoto, K.; Monfray, Patrick; Mouchet, Anne; Orr, James C.; Plattner, Gian-Kasper; Sarmiento, Jorge L.; Schlitzer, Reiner; Slater, Richard D.; Weirig, Marie-France; Yamanaka, Yasuhiro; Yool, Andrew (American Geophysical Union, 2007-08-08)
      Results are presented of export production, dissolved organic matter (DOM) and dissolved oxygen simulated by 12 global ocean models participating in the second phase of the Ocean Carbon-cycle Model Intercomparison Project. ...
    • A modeling study of the seasonal oxygen budget of the global ocean 

      Jin, X.; Najjar, Raymond G.; Louanchi, F.; Doney, Scott C. (American Geophysical Union, 2007-05-09)
      An ecosystem model embedded in a global ocean general circulation model is used to quantify roles of biological and physical processes on seasonal oxygen variations. We find that the thermally induced seasonal net outgassing ...
    • A science plan for carbon cycle research in North American coastal waters. Report of the Coastal CARbon Synthesis (CCARS) community workshop, August 19-21, 2014 

      Benway, Heather M.; Alin, Simone R.; Boyer, Elizabeth; Cai, Wei-Jun; Coble, Paula G.; Cross, Jessica N.; Friedrichs, Marjorie A. M.; Goni, Miguel; Griffith, Peter; Herrmann, Maria; Lohrenz, Steven E.; Mathis, Jeremy T.; McKinley, Galen A.; Najjar, Raymond G.; Pilskaln, Cynthia H.; Siedlecki, Samantha A.; Smith, Richard A. (Ocean Carbon & Biogeochemistry Program, 2016)
      Relative to their surface area, continental margins represent some of the largest carbon fluxes in the global ocean, but sparse and sporadic sampling in space and time makes these systems difficult to characterize and ...
    • Surface ocean pCO2 seasonality and sea-air CO2 flux estimates for the North American east coast 

      Signorini, Sergio R.; Mannino, Antonio; Najjar, Raymond G.; Friedrichs, Marjorie A. M.; Cai, Wei-Jun; Salisbury, Joseph E.; Wang, Zhaohui Aleck; Thomas, Helmuth; Shadwick, Elizabeth H. (John Wiley & Sons, 2013-10-16)
      Underway and in situ observations of surface ocean pCO2, combined with satellite data, were used to develop pCO2 regional algorithms to analyze the seasonal and interannual variability of surface ocean pCO2 and sea-air CO2 ...
