The influence of local winds on wind power characteristics in a High Arctic valley [PDF]
Wind Energy ScienceWind power in the High Arctic is under-developed, and understanding of the local wind conditions is needed. Therefore, the average wind characteristics in the Svalbard valley Adventdalen are investigated using primarily observations from wind profilers ...

Tributary Glacier Surges: An Exceptional Concentration at Panmah Glacier, Karakoram Himalaya [PDF]
, 2007 Four tributaries of Panmah Glacier have surged in less than a decade, three in quick succession between 2001 and 2005. Since 1985, 13 surges have been recorded in the Karakoram Himalaya, more than in any comparable period since the 1850s.

Studying interspecific population synchrony: current status and future perspectives
Ecography, EarlyView.Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Polar Research, 2017 Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While this may reduce herbivore survival,

High-resolution digital outcrop model of the faults, fractures, and stratigraphy of the Agardhfjellet Formation cap rock shales at Konusdalen West, central Spitsbergen [PDF]
Earth System Science DataStructure-from-motion (SfM) photogrammetry has become an important tool for the digitalisation of outcrops as digital outcrop models (DOMs). DOMs facilitate the mapping of stratigraphy and discontinuous structures like folds, faults, and fractures from ...

Land Degradation &Development, EarlyView.ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Nordlit, 2020 Svalbard, or “cool edge” in Old Norse, is an archipelago in the Arctic Ocean. It has no indigenous population and some 60% of its landmass is covered by ice. Yet its rich wildlife and mineral resources, as well as spectacular sights, have been attracting a great deal of commercial interest ever since Willem Barentsz discovered the archipelago in 1596 ...
