Dating of marine sediments by using unsupported 210Pb method

, 2009
In the framework of a more general study on marine species in sediments, it was necessary to obtain a time calibration of the different sections of the sampled sediment columns, both to estimate the pollution of the sediments and, particularly, to study ...

210Po-210Pb disequilibria in polar seas in summer [PDF]

, 2014
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 ...

Importance of lateral transport processes to 210Pb budget in the eastern Chukchi Sea during summer 2003

, 2012
Activity concentrations of dissolved and particulate 210Pb and 226Ra in the water column were measured in the eastern Chukchi Sea during summer 2003. 234Th/238U disequilibria were used to estimate the scavenging fluxes of 210Pb from the water column to ...
