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 originally by NSF OPP ARCSS (1) and next by NASA through the Primary Productivity Algorithm Round Robin activity (PPARR) program. Data were provided in xlsx format and converted by NCEI to csv format.
