The coring was successfully operated on the winter ice-cover of the lake in 2000 and the pioneer practice of the ""off-the-ice"" coring proves to be very useful and economic for taking quality cores from lakes in northern China.A multidisciplinary investigation has been carried out on core HQH4, one of the three 11-m-long cores. Results from previous investigation include lithostratigraphy, radiocarbon dating, paleoecology of Ostracoda, stable isotopic record of ostracod shells, total nitrogen and organic carbon, C/N ratio, 81 C of organic matter etc.
