【Abstract】 Based on the new results of a series of isotopes, known as δD,δ¹⁸O,²²⁴Ra,²²⁶Ra,²²⁸R, Th-isotopic series,²¹⁰Pb,¹⁴C,etc, some developments on isotopic trace techniques for movement of seawater mass, particle dynamics, primary productivity, sediment dynamics and paleoceanography were summarized. Finally, the author suggests that it should be important to develop new tracer technique and integrate different isotopic systems for studying marine environment, evaluating sediment rates and mixing rates, as well as sediment processes on the shallow shelf and marginal sea.更多还原
