The overall spatial and temporal influence of shrub expansion on permafrost is largely unknown due to uncertainty in estimating the magnitude many counteracting processes. For example, shrubs shade ground during snow-free season, which can reduce active layer thickness. At same time, advance timing snowmelt when they protrude through snow surface, thereby exposing thawing earlier spring. Here, we compare 3056 situ frost table depth measurements split between mineral earth hummocks organic...
Ocean ambient noise is a crucial habitat feature for marine animals because it represents the lower threshold of their acoustically active space. Ambient affected by from both natural sources, like wind and ice, anthropogenic such as shipping seismic surveys. During ice-covered season, conditions in Arctic are quieter than those other regions sea ice has dampening effect. warming induced climate change can raise levels reducing coverage increasing human activity, these changes may negatively...
The Arctic is changing rapidly, leading to changes in habitat availability and increased anthropogenic disturbance. Information on the distribution of animals needed as these occur. We examine seasonal presence marine mammals western Canadian near Sachs Harbour, Northwest Territories, using passive acoustic monitoring between 2015 2016. also examined influence environmental variables (ice concentration distance, wind speed) species. Both bowhead whales (Balaena mysticetus) beluga...
Abstract. Envisat ASAR WS images, verified against mass balance, ice core, ground-penetrating radar and air temperature measurements, are used to map changes in the distribution of glacier facies zones across Devon Ice Cap between 2004 2011. Glacier ice, saturation/percolation pseudo dry snow readily distinguishable satellite imagery, superimposed zone can be mapped after comparison with ground measurements. Over study period there has been a clear upglacier migration facies, resulting...
