| 摘 要： | IrocrIowThere is a linkage in shallow marine systerns between sea-noor biOgaxhemical pmeessesand water column pnductivity (Bereson et al., l998). Benthic fluxes provide a significantsource of nutrients to the overlying water tO supPOrt primary pnduction and play a role in de-.creasing oxygen concentrations (van et al., l999; Cowan and Boynton, l996; Berelson etal., 1998; Friedl et al., l998; Zabel et al., l998). TherefOre, it is imPOrtant to define theediment di8genetic pathways for the …

| Abstract: | Investigations of sediment-water fluxes of nutrients in the Bohai Sea were carried out in September - October 1998 and April - May 1999. The exchange fluxes of nutrients between sediment and sea water were determined by incubating the core-top sediments with overlying water aerated with air. The benthic fluxes of NO3- , NO2- , NH4 , DIN, DON and TON in the first cruise and the flux-es of NO3 , NO2- , NH4 , DIN, DON, TDN, PO43- , DOP and TDP in the second cruise were measured. The exchange fluxes of nutrients in fall were higher than in spring. The benthic nutrient fluxes represented 15% -55% of nutrient budgets in the Bohai Sea. |
