Pathways of contaminants to the Arctic

Many POPs (persistent organic pollutants), heavy metals and other contaminants from emissions further south are accumulated in Arctic food chains and ultimately in indigenous peoples. This process is [..]

PCBs in the blood of Arctic residents

Many POPs (persistent organic pollutants) and heavy metals from emissions further south are accumulated in Arctic food chains and ultimately in indigenous peoples. While fear of these compounds [..]

Vegetation density/distribution in the high Arctic

The current vegetation density and distribution in the high Arctic can be calculated using satellite images. The vegetation index, 'greenness' (NDVI) represents a benchmark of the presence and ratio [..]

Glacier shrinking on Cumberland Peninsula, Baffin Island, Canadian Arctic

A new glacier inventory based on satellite data shows that the glacier cover reduced by about 22 per cent between the Little Ice Age (LIA) maximum extent and 2000. Changes in glacier area and volume [..]

Current marine shipping uses in the Arctic

Biological invasions are known from around the globe but are relatively less known or studied in the Arctic. This secondary migration of invasives complicates ecological interactions as naturally [..]

Distribution of polar bear populations in the Arctic

Worldwide there are thought to be 22,000-27,000 polar bears (Ursus maritimus)in 20 separate populations. They can be found in the United States, Canada, Russia, Greenland and on the Arctic islands of [..]

Tree line in the Arctic

This graphic shows the location of the arctic tree line. Boreal forest occurs only to the south of the tree line (the dark green line on the graphic). The Arctic area, as defined by the Arctic [..]

Arctic, topography and bathymetry

(See http://maps.grida.no/go/graphic/arctic-topography-and-bathymetry1 for an updated version of this map) The Arctic is extremely diverse in terms of landscapes, varying from pack and drift ice to [..]

Arctic pelagic food web

The marine animal food chain is very complex and multilayered as are most food chains. This is a quick reference to represent the complete food chain in regards to pelagic crustaceans and [..]

Coastal Arctic food web (drift ice)

The coastal Arctic food web is closely related to drift ice conditions and seasonal use of shorelines by both terrestrial and sea mammals. Numerous species depend upon each other and the transport of [..]

Arctic, AMAP and CAFF area

Identifying and defining the Arctic is not necessarily obvious, as this map illustrates. The Arctic Council working groups on conservation and pollution operate with slightly different definitions due [..]

Satellite observations in Arctic sea ice, 1979 and 2003

This oblique view of the Arctic polar ice cap in September shows the significant reduction that has happened over a time period just over 20 years, from 1979 to 2003. Future predicitions shows even [..]

The decrease of Arctic sea ice, minimum extent in 1982 and 2007, and climate projections [Norwegian]

Sattelite observations of the september extent of sea ice in the Arctic shows in 2007 shows a 23% decrease from the previous minimum, in 2005, and 39% below the average minimum extent for the time [..]

Fossil fuel resources and oil and gas production in the Arctic

The Arctic has been opened up for increased exploration of petroleum, gas and mining activities. The Barents Sea, the Mackenzie Valley in Canada and the Alaskan North Slope, are the areas of chief [..]
