  • Estimating mixed layer nitrate in the North Atlantic Ocean 

    Steinhoff, T., T. Friedrich, S. E. Hartman, A. Oschlies, et al. 2010. "Estimating mixed layer nitrate in the North Atlantic Ocean." Biogeosciences 7(3): 795-807.
    Here we present an equation for the estimation of nitrate in surface waters of the North Atlantic Ocean (40 degrees N to 52 degrees N, 10 degrees W to 60 degrees W). The equation was derived by multiple linear regression ...

  • Estimating the monthly pCO(2) distribution in the North Atlantic using a self-organizing neural network 

    Telszewski, M., A. Chazottes, U. Schuster, A. J. Watson, et al. 2009. "Estimating the monthly pCO(2) distribution in the North Atlantic using a self-organizing neural network." Biogeosciences 6(8): 1405-1421.
    Here we present monthly, basin-wide maps of the partial pressure of carbon dioxide (pCO(2)) for the North Atlantic on a 1 degrees latitude by 1 degrees longitude grid for years 2004 through 2006 inclusive. The maps have ...

  • Methodological Underestimation of Oceanic Nitrogen Fixation Rates 

    Mohr, Wiebke, Tobias Grosskopf, Douglas W. R. Wallace, and Julie LaRoche. 2010. "Methodological Underestimation of Oceanic Nitrogen Fixation Rates." Plos One 5(9): 12583-e12583.
    The two commonly applied methods to assess dinitrogen (N(2)) fixation rates are the (15)N(2)-tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two methods as well as inconsistencies between ...

  • Nitrous oxide in the North Atlantic Ocean 

    Walter, S., H. W. Bange, U. Breitenbach, and D. W. R. Wallace. 2006. "Nitrous oxide in the North Atlantic Ocean." Biogeosciences 3(4): 607-619.
    In order to get a comprehensive picture of the distribution of nitrous oxide (N(2)O) in the North Atlantic Ocean, measurements of dissolved nitrous oxide were made during three cruises in the tropical, subtropical and ...
