JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 116, F03009. Abstract The ice cap Vestfonna in the northern Svalbard archipelago is one of the largest ice bodies of the European Arctic (similar to 2400 km(2)), but little is known about its mass balance.

Vestfonna (Fig. 2) reveal a mean bulk density of Snow depth on De Geerfonna was found to be 388 ⫾ 43 kg m-3 (mean ⫾ one standard deviation) distinctly higher than at comparable terrain eleva- over all 22 snow profiles, which is in good agree- tions on Vestfonna (Table 1). We analysed a 34‐year data record of multi‐spectral satellite imagery in order to study changes in glacier frontal positions of the ice cap Vestfonna. A consistent pattern of almost steady retreat of the southern and north‐eastern outlet glaciers of the ice cap is observed while Franklinbreen, the only major outlet glacier draining towards the north‐west shows re‐advance. In this study we compile and present snow cover information obtained from 22 snow pits that were dug on Vestfonna during this period.

However, for the ice cap Vestfonna, in northeastern Svalbard, climatic mass balance modelling has suggested almost balanced conditions over a period of nine years (2000–2009). A slightly positive geodetic mass balance (1990–2005) has been reported from a comparison of laser altimetry to older DEMs. Vestfonna Geophysical har besøksadresse Jacob Aalls Gate 44 B, 8310 Kabelvåg (Vågan, Nordland).

We model the climatic mass balance of the ice cap for the period September 2000 to August 2009 on a daily basis. Fieldwork. [5] Between May and June 1995, an electromechanical drill ( Figure 1) was used to obtain an ice core from the top of Vestfonna Ice Cap in Nordaustlandet, Svalbard (79°58′N, 21°01′E, 600‐m a.s.l.).

The snow pit samples showed that the temperature increased during the winter owing to advection of warm air from the south, and δ18O did not show a seasonal cycle.
