Sedimentological characteristics of ice-wedge polygon terrain in Adventdalen (Svalbard) – environmental and climatic implications for the late Holocene
Ice wedge periglacial landscape svalbard river terraces radioactive carbon s
2015/1/6
Ice wedges are widespread periglacial features in the landscape of Adventdalen, Svalbard. The networks of ice wedges have created areas with well-developed polygonal terrains in the lowest fluvial ter...
Direct determination of nitrogen cycling rates and pathways in Arctic fjord sediments (Svalbard, Norway)
pathways nitrogen cycling rates
2014/4/16
Results from a study of benthic nitrogen cycling in two Arctic fjords are presented. Intact sediment core
incubations were used to quantify net fluxes of dissolved inorganic nitrogen, organic nitroge...

2010/2/21
This paper reports on backscatter and depolarization measurements by an airborne lidar in the Arctic during the ASTAR 2004 campaign. A unique weather situation facilitated the observation of the aeros...
Geometric changes and mass balance of the Austfonna ice cap,Svalbard
Geometric changes mass balance Austfonna ice cap
2010/2/3
The dynamics and mass balance regime of the Austfonna ice cap, the largest glacier on Svalbard, deviates significantly from most other glaciers in the region and is not fully understood. We have compa...
The effect of misleading surface temperature estimations on the sensible heat fluxes at a high Arctic site – the Arctic Turbulence Experiment 2006 on Svalbard (ARCTEX-2006)
misleading surface temperature sensible heat fluxes ARCTEX
2010/1/18
The observed rapid climate warming in the Arctic requires improvements in permafrost and carbon cycle monitoring, accomplished by setting up long-term observation sites with high-quality in-situ measu...

polar dinosaurs-new finds Lower Cretaceous Svalbard
2009/12/3
A new discovery of ornithopod dinosaur tracks from Svalbard is described. The Lower Cretaceous (Barremian) section at Isfjorden consists of sandstones and interbeds consistent with an alluvial flood p...

Dinoflagellate cyst assemblages inshore and offshore Svalbard modern hydrography climate
2009/12/2
Thirty-six seabed samples from inshore and offshore Svalbard and the northern part of the Barents Sea were collected for dinoflagellate cyst (dinocyst) analysis. Svalbard is an important locality repr...
Diagnostic and prognostic simulations with a full Stokes model accounting for superimposed ice of Midtre Lovénbreen,Svalbard

N~-Alesundw, here the subpermafrost aquif...
Fluxes of Water and Energy from Three High Latitude Tundra Sites in Svalbard
Fluxes of Water Three High Latitude Tundra Sites Svalbard
2009/10/23
Measurements of the surface fluxes of radiation, heat and water vapour were
made at three tundra sites near N~-Alesund, Svalbard for the active seasons
(June to September) of 1995 and 1996. In 1995 ...
Snow Distribution at a High Arctic Site at Svalbard
Snow Distribution High Arctic Site Svalbard
2009/10/23
In the Arctic regions snow cover has a major influence on the environment both
in a hydrological and ecological context. Due to strong winds and open terrain
the snow is heavily redistributed and th...
An Energy Balance Based HBV- Model with Application to an Arctic Watershed on Svalbard,Spitsbergen
Energy Balance HBV- Model Arctic Watershed
2009/10/22
In several studies of snowmelt using the temperature index method from the original HBV-model, the model fails to predict the timing of the snowmelt and underestimates the intensities on occasions wit...
