Product database composed of physical and nutrient profile data collected in the Arctic Ocean and adjacent seas from 1928 to 2008 (NODC Accession 0072133)

The nitrate, nitrite, and nitrate +nitrate data and phosphate data in this file were used to estimate Net Community Production (NCP) from seasonal changes in nutrient concentrations (Codispoti et al., submitted). They comprise an edited suite of data from the following databases: An Arctic nutrient data (ARCNUT) base assembled under the direction of G. Cota and L. Pomeroy (http://data.eol.ucar.edu/codiac/dss/id=62.015), the Eurocean database (http://www.eur-oceans.eu/integration/wp2.2), an initial version (2009) of the CARINA database http://cdiac.ornl.gov/oceans/CARINA/Carina_inv.html), and the Hydrochemical Atlas of the Arctic Ocean (Colony and Timokhov, 2001). These data were supplemented with observations from the Western Arctic Shelf-Basins Interaction Program (Codispoti et al., 2005 &2009), data from the Fram III expedition (Packard and Codispoti, 2007), data from the Canadian Archipelago supplied by F. McLaughlin, and data from a recent expedition to the Canadian Archipelago and Baffin Bay supplied by K. Falkner.
