Multiyear accumulation and temperature history near the North Greenland Ice Core Project site, north central Greenland
This paper presents a comparison of two independent methods of estimating subseasonal accumulation across the interior of Greenland. These methods, highresolution snow pit studies and atmospheric modeling, have differing spatial and temporal resolution, but both can estimate net accumulation for subseasonal and shorter periods. The snow pit approach is based on a documented relationship between...

A new collection of mantle xenoliths in Tertiary dykes from the Wiedemann Fjord area in Southeast Greenland shows that this part of the central Greenland craton is underlain by highly depleted peridotites. The samples are mostly spinel Ž . harzburgites with highly forsteritic olivines Fo , average Fo . This, together with unusually high modal olivine 87– 94 92.7 Ž . contents 70–)95% , places th...
