Description :
The AA. analyse ice cores from Vestfonna ice cap (Nordaustlandet, Svalbard). Density profiles and oxygen isotopic measurements were made on 3 firn cores from the 2 highest summits of the glacier located on the SW–NE and NW–SE central ridges. The results were used in order to extract recent climate information missing for the last 20 years and compare precipitation regimes and provenance at the 2 sites. These new data can be used to extend the data from the earlier deeper cores into the twenty-first century.
