Estimating mixed layer nitrate in the North Atlantic Ocean
(2010)
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 ...
Methodological Underestimation of Oceanic Nitrogen Fixation Rates
(2010-09)
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 ...
Contrasting biogeochemistry of nitrogen in the Atlantic and Pacific Oxygen Minimum Zones
(2012)
We present new data for the stable isotope ratio of inorganic nitrogen species from the contrasting oxygen minimum zones (OMZs) of the Eastern Tropical North Atlantic, south of Cape Verde, and the Eastern Tropical South ...
