The ice cap Vestfonna in the northern Svalbard archipelago is one of the largest ice bodies of the European Arctic (∼2400 km 2 ), but little is known about its mass balance. We model the climatic mass balance of the ice cap for the period September 2000 to August 2009 on a daily basis. Vestfonna Geophysical AS, Trondheim, Norway Hans E. F.

The radar is operating from 150–1200 MHz and is using an Ultra Wideband Bow-Tie Slot Vestfonna is an independent geophysical service company specialised in data integration between CSEM (Controlled source electromagnetic), seismic and well data. A spatial comparison of snow water equivalents above the previous end‐of‐summer surface serves for obtaining insights into the spatial distribution of snow accumulation across Vestfonna. Altitude was found to be the only significant spatial parameter for controlling snow accumulation across the ice cap. 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. Altitude was found to be the only Vestfonna and De Geerfonna (Nordaustlandet, Svalbard) – a significant spatial parameter for controlling snow spatiotemporal analysis based on multiyear snow-pit data.

De skal jobbe med undersøkelsene som skal gjøres på Mars – i all hovedsak med instrumentet Rimfax. Testet på norsk grunn. UiO-teamet jobber for tiden med hvordan geologisk informasjon kan bli tolket ut av dataene fra Rimfax-radaren.

Extensive glaciological field measurements were carried out on the ice cap Vestfonna as well as on the minor ice body De Geerfonna (Nordaustlandet, Svalbard) within the framework of IPY Kinnvika. Field campaigns were conducted during the period 2007–2010 in spring (April/May) and summer (August). 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.

A GPR is made of an electronics unit and an antenna. The radar transmits ra-dio frequency electromagnetic waves into the subsurface, typically operating in the 10– reduced geophysical data are stored on a direct-access computer 2 database.
In this study we compile and present snow cover information obtained from 22 snow pits that were dug on Vestfonna during this period. Locations are along two transects on the northwestern, land terminating slope of the ice cap, on its central summit, Ahlmann Summit, and at a set of several other locations in the eastern and northern part of the ice cap.
All of the fast outlet glaciers on Vestfonna are thought to be topographically controlled (Pohjola et al., 2011) and Founder at Vestfonna Geophysical and AMASE. Co-I on Mars 2020 Rimfax.
