dc.description.abstract本研究利用中国第28次南极科学考察和中国第5次北极科学考察航次获得的210Po、210Pb数据,研究了210Po、210Pb在极地海域的生物地球化学行为,揭示了南极半岛附近海域和白令海的颗粒动力学特征,计算出南极半岛附近海域及白令海颗粒有机碳的输出通量。 南极半岛附近海域210Po的活度浓度为0.74~3.17Bq/m3,平均为1.91Bq/m3。溶解态210Po占总210Po的比例介于50%~99%之间,平均为91%,溶解态是研究海域210Po的主要存在形式。210Pb的活度浓度为1.40~5.08Bq/m3,平均为2.93Bq/m3。溶解态210Pb占总210Pb的比例平均为88%,是2...
dc.description.abstractWater samples were collected during the 28th Chinese Antarctic Research Expedition and the 5th Arctic Research Expedition in 2012 summer. Biogeochemical cycle of 210Po and 210Pb were studied in the polar seas. The particle dynamics were revealed and particulate organic carbon (POC) export fluxes were evaluated in the Antarctic Peninsula sea areas and Bering Sea. The total 210Po activity conce...
