Summary
Uptake rates of ammonium, nitrate and urea were measured during the EPOS leg 1 cruise to the Weddell Sea in October–November 1988 using the isotope 15N. Nitrate was the most important nitrogen source both for ice algae (f-ratio ≥0.88) and for phytoplankton in the water column (f-ratio ≥0.85). Indications of a gradual decrease in % new production with time were found in the outer marginal ice zone. Nitrogen uptake rates in ice algae from the sub-ice assemblage were light-limited at in situ irradiances. Significant regeneration of ammonium was found in ice algal samples only.
Data presented here were collected during the European Polarstern Study (EPOS) sponsored by the European Science Foundation
