The dynamics of Vestfonna ice cap (Svalbard) are dominated by fast-flowing outlet glaciers. Its mass balance is poorly known and affected dynamically by these fast-flowing outlet glaciers. Hence, it is a challenging target for ice flow modeling.

Particularly along the margin of larger ice caps, persistent katabatic winds become often strong enough to effectively remove snow from the surface and re-accumulate the eroded snow mass within the surrounding areas.

the northwest part of the glacial cover of the island of Svalbard, in the Spitsbergen Archipelago. Vestfonna belongs to Norway. Area, 2,800 sq km, highest elevation, 637 m. The ice in the center of the glacial cover is 120m thick, and the annual accumulation of snow is more than 1,000 mm.

The old Kinnvika station in Svalbard served as the logistic platform for the For Vestfonna, this amount is assumed to reach 90% of the accumulation sum of the preceding winter season 13, i.e. we set P max = 0.9. Any further meltwater or rainfall input is assumed to leave the glacier system as runoff. With the value of 0.9 we depart from the original value of 0.6 used by ref. 51. 2015-01-01 Vestfonna is an ice cap located on the western part Nordaustlandet in the Svalbard archipelago in Norway.
The polythermal ice cap Vestfonna covers an area of 2340 km2 (Reference Braun Braun and others, 2011) of the island Nordaust-landet (northernmost Svalbard archipelago) at around 80° N extending between sea level and ∼630 m a.s.l. Along with the much larger neighbouring Austfonna and Icelandic VatnaJökull, it is among the largest ice masses of the European Arctic.

The date at which the equilibrium line rises above the summit of Vestfonna (630 m above sea level) is calculated to range between 2040 and 2150, depending on scenario. PMCID: PMC4308701 PMID: 25628045 [Indexed for MEDLINE] Publication Types: Glaciers in Svalbard have shown considerable mass loss in recent years with a reported acceleration in the western and southern parts of the archipelago. 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). The date at which the equilibrium line rises above the summit of Vestfonna (630 m above sea level) is calculated to range between 2040 and 2150, depending on scenario.

Understanding the response of fast flowing ice streams or outlet glaciers to changing climate is crucial in order to make reliable projections of sea level change over the coming decades.
Sustainability, climate-change mitigation, and biomedical science are key areas for future research prowess in the Asia-Pacific region. 2011-07-24 20 Vestfonna ice cap is located on the island Nordaustlandet in the Northeastern Svalbard archipelago (Fig.

Glaciären täcker ett område på cirka 2 500 km 2 . Lågøya ligger cirka 210 km nordöst om Longyearbyen och cirka 6 km nordväst om Nordaustlandet nära glaciären Vestfonna. Öns geografiska koordinater är bland annat sedimentologi, paleontologi, georadar och bathymetri. Se forskarrapport Kinnvika and Vestfonna expeditions 2009 Kinnvika station, vår 2009. Norges största glaciärer. Austfonna, Olav V och Vestfonna. Den 8 412 kvadratkilometer stora Austfonna på Svalbard anses vara Europas största istäcke till ytan, Den är täckt av två stora inlandsisar, Austfonna och Vestfonna, som ligger på ömse sidor om fjorden.
Vårens arbeten hade fokus på isdynamik och meteorologi på kalottisen Vestfonna. Sommarens expeditioner koordinerades från det polska forskningsfartyget RV Horyzont II och innehöll bland annat sedimentologi, paleontologi, georadar och bathymetri.
