Description
Summary:Considerable drawdown of total dissolved inorganic carbon (CT) and oversaturation of oxygen (O2) within a cold (,15uC) oligotrophic eddy in the extratropical North Atlantic Ocean (46uN, 20.5uW) indicate that, despite), the eddy was highly productive. Estimates of net community production using the the absence of nitrate (NO { 3 mass balances of CT and O2 were two to five times greater than those obtained using the mass balance of NO { 3. The remineralization rates obtained using the integrated rates of CT and NO { 3 accumulation and O2 utilization for the upper thermocline waters (35–300-m depth) were in agreement with CT- and O2-based net community production over the same period; however, all the estimates exceeded the NO { 3-based net community production by a factor of two to five, pointing to a considerable accumulation of NO { 3 in the upper thermocline in excess of changes in the mixed-layer NO { 3 inventory. The amount of this excess NO { 3 suggests that a considerable fraction inventory and that an external of the net community production was not supported by the mixed-layer NO { 3
