Description
Particulate organic carbon (POC) and nitrogen (PON) concentrations and fluxes were measured in the Gdańsk Deep (Gulf of Gdansk) from 30.05 to 06.06.2001. The vertical profiles of POC and PON were characterised by the highest values in the euphotic layer, a gradual decrease with depth, and an increase below the halocline. The hydrophysical conditions had a decisive impact on POC and PON fluxes in the water column. Preferential removal of nitrogen from suspended mater was observed in the entire water column (maximum – in the vicinity of thermocline).
The water samples from the water column were taken with a rosette sampler (Ocean Test Equipment Inc.) and measurements of water temperature, conductivity and depth were done with a CTD profiler (Falmouth Scientific Inc.). The analyses of POC and PON were performed on a CHNS/O 2400 Perkin Elmer analyser according to acetanilide standards. Chlorophyll a and phaeopigment a were determined with a spectrophotometer on acetone (90%) extracts.
