This dataset contains oxygen isotope, dust, anion, and accumulation data from the 308.6-meter-deep ice core drilled at the Guliya Ice Cap in the West Kunlun Mountains, Qinghai-Tibet Plateau in 1992. A total of 12628 sliced samples were used for oxygen isotope analysis, 12480 samples for dust concentration research, and 9681 samples for anion concentration research. Data source: National Centers for Environmental Information (http://www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets/ice-core). Data processing method: Averaging. This dataset includes 4 tables of data, which are: Oxygen isotope, dust and anion data of Guliya Ice Core at different depths; 10-year average data of oxygen isotope, dust, anion and net accumulation of Guliya Ice Core; 400-year average data of oxygen isotope, dust and anion of Guliya Ice Core; and chlorine-36 data at different depths.
