Nitrate and ammonium uptake rates were measured by the 15N tracer technique in Antarctic waters. The ratio f= NOs- uptake NOs- uptake + NH4+ uptake averaged 0.54 in the Scotia Sea in early spring and 0.40 in the Ross Sea in summer, indicating that NO,- and NH4+ contribute about equally to primary pr...
