英文摘要	The aim of this paper is to quantify submarine groundwater discharge (SGD) into the northeast coast of Jiaozhou Bay, then estimate the SGD-derived nutrient fluxes. At Dongdayang dock located at the north shoreline of Jiaozhou Bay, the author deployed one in-situ 48 h continuous experiment for measuring 222Rn activity in seawater, in October 2011 and May 2012, respectively. Through establishing 222Rn mass balance model at the observing site, the average SGD rates are assessed to be 6.38 cm/d for October 2011 and 8.29 cm/d for May 2012. Measured results show the SGD rates fluctuate greatly, daily and seasonally, which are mainly controlled by precipitation, tidal pump and wave oscillation. Based on the SGD rates, the SGD-derived nutrient fluxes are calculated to be 47.0×103-48.6×103 mol/d for DIN (dissolved inorganic nitrogen), 15.5×103-17.3×103 mol/d for the soluble SiO2, and 0.6×103 mol/d for DIP (dissolved inorganic phosphorus), respectively. These SGD-derived nutrient fluxes contribute to the eutrophication in Jiaozhou Bay to a certain degree which need due attention.
