Oxygen Isotope, dust, anion and accumulation data from the Dunde Ice Core (1987)- A Big Earth Data Platform for Three Poles

This data set contains data from the three ice cores drilled from the Dunde ice cap in the northern Tibetan Plateau in 1987. Core D-1 has a length of 139.8 m and is divided into 3585 samples for isotope analysis. Core D-3 has a length of 138.4 m, and the upper 56 m was cut into several samples on site and stored in bottles after melting, while the remaining length was frozen and preserved.

The data set contains three data tables, namely, 10-year mean oxygen isotope data for the Dunde ice core (520-1987 A.D.), 5-year mean water equivalent accumulation data for Dunde ice core and 10-year mean dust data for the Dunde ice core.

Data source: National Centers for Environmental Information (http://www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets/ice-core).

Processing method: Average.
