Water temperature, primary productivity-phytoplankton, chlorophyll-a concentration, and other data collected by CTD, scintillation counter, fluorometer, and other instruments from Arctic Ocean from 1959-08-03 to 2011-10-21 (NCEI Accession 0161176)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 02:56 AM | Dataset Last Updated: March 06, 2018 at 12:00 AM
Arctic Ocean net primary productivity (NPP) was assembled for 1959-2011 from existing databases and recent polar research cruises. At each NPP station, if available, other data such as Chl-a, nitrate, and nitrite concentrations, mixed layer depth (MLD), SST, and euphotic layer depth were included. The data were obtained between 65 and 89°N mainly from late spring to early fall. At each station, NPP was measured at various depths using 13C- or 14C-labeled compounds. Surface fluorometric Chl-a concentration and SST were estimated from measurements between 0 and 5 m depth. MLD was estimated from CTD profiles using 0a threshold criterion. Nitrate and nitrite concentrations were measured only in the upper 100 m. Sponsored by the NASA through the Primary Productivity Algorithm Round Robin activity (PPARR) program. Data were provided in xlsx format and converted by NCEI to csv format.
