Identifying factors that drive seasonal and spatial patterns in marine primary production in Greenland coastal waters

During the growth season of 2013 a multi-disciplinary team of researchers conducted cruises in the Godthaabsfjord to study temporal and spatial variations of the factors regulating pelagic primary production. In May, August and October, GCRC’s R/V Sanna facilitated studies of the influence of light and nutrients on primary production using 14-C incubations, and O2  net and gross production. In September, a suite of methodological approaches to estimate new and regenerated production, net and gross production, particulate and dissolved production and production and re-mineralization of carbon were employed. Techniques included 14C, O2 and variable fluorescence techniques. Results were compared to in situ C-14 incubations from the Marine-basic monitoring program. The project will continue in Young Sound in 2014.
