| 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 TDN in the first cruise and the fluxes 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. |
