3 results for “Nitrate isotope ratios”
Data to accompany "Stable isotope ratios in seawater nitrate reflect the influence of Pacific water along the northwest Atlantic margin".
<p>This dataset accompanies the article by Owen A. Sherwood, Samuel H. Davin, Nadine Lehmann, Carolyn Buchwald, Evan N. Edinger, Moritz F. Lehmann, and Markus Kienast: "Stable isotope ratios in seawater nitrate reflect the influence of Pacific water along the northwest Atlantic margin", Biogeosciences, 18, 1–20, 2021. <a href="https://doi.org/10.5194/bg-2021-45">https://doi.org/10.5194/bg-2021-45</a>.</p> <p>The dataset comprises nutrient concentrations and nitrate isotope ratios for “bottle” samples of seawater collected by CTD/Rosette from 25 stations along the northwest Atlantic Ocean, from the Labrador shelf to northern Baffin Bay. Seawater physical properties measured by CTD are also provided for the depths at which bottle samples were collected. The complete sampling and analytical methods are provided in the accompanying article. </p>
Nitrogen isotope ratios of nitrate, ammonium, and amino acids in sinking particles in the Northwestern North Pacific
<p>The database includes sample information and nitrogen isotope measurements of nitrate, ammonium, and amino acids in sinking particles in the Northwestern North Pacific. The sinking particles were collected in sediment traps moored at depths of 200, 500, and 4,810 m at station K2 (47°N, 160°E; water depth, ~5,200 m). The seawater was sampled with a plastic bucket for the surface and Niskin-X sampling bottles for water below the surface at stations K2 and KNOT (44°N, 155°E). The model package of a 1D nitrogen isotope model includes model source code written in Fortran 90, forcing, and initial condition at station K2.</p>
