  • Air-sea CO2 flux in the Pacific Ocean for the period 1990–2009 

    Ishii, Masao; Feely, Richard A.; Rodgers, Keith B.; Park, Geun-Ha; Wanninkhof, Rik; Sasano, D.; Sugimoto, H.; Cosca, C. E.; Nakaoka, S.; Telszewski, Maciej; Nojiri, Yukihiro; Mikaloff Fletcher, Sara E.; Niwa, Y.; Patra, Prabir K.; Valsala, V.; Nakano, H.; Lima, Ivan D.; Doney, Scott C.; Buitenhuis, Erik T.; Aumont, Olivier; Dunne, John P.; Lenton, A.; Takahashi, Taro (Copernicus Publications on behalf of the European Geosciences Union, 2014-02-06)
    Air–sea CO2 fluxes over the Pacific Ocean are known to be characterized by coherent large-scale structures that reflect not only ocean subduction and upwelling patterns, but also the combined effects of wind-driven gas ...
  • An assessment of the Atlantic and Arctic sea–air CO2 fluxes, 1990–2009 

    Schuster, Ute; McKinley, Galen A.; Bates, Nicholas R.; Chevallier, F.; Doney, Scott C.; Fay, A. R.; Gonzalez-Davila, M.; Gruber, Nicolas; Jones, S.; Krijnen, J.; Landschutzer, P.; Lefevre, N.; Manizza, Manfredi; Mathis, Jeremy T.; Metzl, Nicolas; Olsen, A.; Rios, Aida F.; Rodenbeck, C.; Santana-Casiano, J. M.; Takahashi, Taro; Wanninkhof, Rik; Watson, Andrew J. (Copernicus Publications on behalf of the European Geosciences Union, 2013-01-29)
    The Atlantic and Arctic Oceans are critical components of the global carbon cycle. Here we quantify the net sea–air CO2 flux, for the first time, across different methodologies for consistent time and space scales for the ...
  • Changes in deep-water CO2 concentrations over the last several decades determined from discrete pCO2measurements 

    Wanninkhof, Rik; Park, Geun-Ha; Takahashi, Taro; Feely, Richard A.; Bullister, John L.; Doney, Scott C. (Elsevier Ltd, 2013-02-09)
    Detection and attribution of hydrographic and biogeochemical changes in the deep ocean are challenging due to the small magnitude of their signals and to limitations in the accuracy of available data. However, there are ...
  • Global ocean carbon uptake : magnitude, variability and trends 

    Wanninkhof, Rik; Park, Geun-Ha; Takahashi, Taro; Sweeney, Colm; Feely, Richard A.; Nojiri, Yukihiro; Gruber, Nicolas; Doney, Scott C.; McKinley, Galen A.; Lenton, A.; Le Quere, Corinne; Heinze, Christoph; Schwinger, J.; Graven, Heather; Khatiwala, S. (Copernicus Publications on behalf of the European Geosciences Union, 2013-03-22)
    The globally integrated sea–air anthropogenic carbon dioxide (CO2) flux from 1990 to 2009 is determined from models and data-based approaches as part of the Regional Carbon Cycle Assessment and Processes (RECCAP) project. ...
  • North Pacific carbon cycle response to climate variability on seasonal to decadal timescales 

    McKinley, Galen A.; Takahashi, Taro; Buitenhuis, Erik T.; Chai, Fei; Christian, James R.; Doney, Scott C.; Jiang, Mingshun; Lindsay, Keith; Moore, J. Keith; Le Quere, Corinne; Lima, Ivan D.; Murtugudde, Raghu; Shi, L.; Wetzel, P. (American Geophysical Union, 2006-07-04)
    Climate variability drives significant changes in the physical state of the North Pacific, and thus there may be important impacts of climate variability on the upper ocean carbon balance across the basin. We address this ...
  • Oceanic sources, sinks, and transport of atmospheric CO2 

    Gruber, Nicolas; Gloor, Emanuel; Mikaloff Fletcher, Sara E.; Doney, Scott C.; Dutkiewicz, Stephanie; Follows, Michael J.; Gerber, Markus; Jacobson, Andrew R.; Joos, Fortunat; Lindsay, Keith; Menemenlis, Dimitris; Mouchet, Anne; Muller, Simon A.; Sarmiento, Jorge L.; Takahashi, Taro (American Geophysical Union, 2009-02-18)
    We synthesize estimates of the contemporary net air-sea CO2 flux on the basis of an inversion of interior ocean carbon observations using a suite of 10 ocean general circulation models (Mikaloff Fletcher et al., 2006, ...
  • Sea–air CO2 fluxes in the Southern Ocean for the period 1990–2009 

    Lenton, A.; Tilbrook, Bronte; Law, R. M.; Bakker, Dorothee C. E.; Doney, Scott C.; Gruber, Nicolas; Ishii, Masao; Hoppema, Mario; Lovenduski, Nicole S.; Matear, Richard J.; McNeil, B. I.; Metzl, Nicolas; Mikaloff Fletcher, Sara E.; Monteiro, P. M. S.; Rodenbeck, C.; Sweeney, Colm; Takahashi, Taro (Copernicus Publications on behalf of the European Geosciences Union, 2013-06-19)
    The Southern Ocean (44–75° S) plays a critical role in the global carbon cycle, yet remains one of the most poorly sampled ocean regions. Different approaches have been used to estimate sea–air CO2 fluxes in this region: ...
  • Skill metrics for confronting global upper ocean ecosystem-biogeochemistry models against field and remote sensing data 

    Doney, Scott C.; Lima, Ivan D.; Moore, J. Keith; Lindsay, Keith; Behrenfeld, Michael J.; Westberry, Toby K.; Mahowald, Natalie M.; Glover, David M.; Takahashi, Taro (2008-03-04)
    We present a generalized framework for assessing the skill of global upper ocean ecosystem-biogeochemical models against in-situ field data and satellite observations. We illustrate the approach utilizing a multi-decade ...
