A 1500-year record of mercury isotopes in seal feces documents sea ice changes in the Antarctic

The seal excrement sediment core HF4, 42.5 cm long, was collected from a terrestrial catchment (62º11'57"S, 59º58'48"W) of a depositional basin located in the second marine terrace with an altitude of 8 m and on the west coast of Fildes Peninsula, during the Eighteenth Chinese Antarctic Research Expedition (November 2001–March 2002). This dataset contains mercury concentration, mercury isotopes, and seal hair counts in HF4 sediment profiles.2001年11月至2002年3月中国第18次南极科学考察期间，于菲尔德斯半岛西海岸海拔8 m的第二级海成阶地沉积盆地的陆地集水区（南纬62°11′57″，西经59°58′48″），采集得到总长42.5 cm的海豹粪便沉积岩芯HF4。本数据集包含HF4沉积剖面中的汞浓度、汞同位素及海豹毛发计数数据。
