Arctic, topography and bathymetry 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 rugged shores, flat coastal plains, rolling hills and mountains surpassing 6000 metres above sea level (Denali, 6,194 m asl, in sub-arctic and boreal Alaska). The region has rivers and lakes, tundra and the largest forests in the world (the Russian Tai...

Projected changes in Arctic pack ice (sea ice minimum extent) Projected changes in Arctic pack ice (sea ice minimum extent)
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) for the Arctic sea ice extent (the permanent ice) are presented in this map, with the successive decrease in the ice up to 2090. The projections are based on the models of the IPCC Third Assessment Report (IPCC TAR).

Development of fossil fuel resources in the Arctic, 2005 Development of fossil fuel resources in the Arctic, 2005
Barents Sea: The 2004 lifting of an embargo on offshore hydrocarbon exploration in the Norwegian Barents has renewed activity there. Regulation of exploration is animportant political issue. Debate in 2005 focused on environmental protection and establishing areas free of oil development. In Russia five companies were selected as finalists in the joint development of the Shtokman gas field, in the Barents Sea. This field is estimated to hold twic...

Arctic sea routes - Northern sea route and Northwest passage Arctic sea routes - Northern sea route and Northwest passage
Sea routes along the edges of the Arctic ocean, or rather along the coasts of Northern Canada and Russia, holds potential for decreasing the number of days in shipping goods from the Pacific to Atlantic coasts in Europe and North America, and vice versa. In addition, this could provide a means to transport natural resources, such as oil and gas, extracted in the Arctic. Currently these routes have not been possible to use this, due to the ice con...

Thinning of the Arctic sea-ice Thinning of the Arctic sea-ice
Sea-ice draft is the thickness of the part of the ice that is submerged under the sea. Comparison of sea-ice draft data acquired on submarine cruises between 1993 and 1997 with similar data acquired between 1958 and 1976 indicates that the mean ice draft at the end of the melt season has decreased by about 1.3 m in most of the deep water portion of the Arctic Ocean, from 3.1 m in 1958-1976 to 1.8 m in the 1990s. In summary: ice draft in the 1990s...

Human impact on the Arctic environment 2002 Human impact on the Arctic environment 2002
Human activities influence the environment and reduce the value of forests, tundra and plains in terms of original biodiversity and habitat. Primarily larger mammals are hit by the fragmentation caused by roads and pipelines. The GLOBIO methdology has modeled the current impact of human activities in the Arctic, as seen in this map. Infrastructure and settlements are used as proxies for human activities.

Arctic development hotspots Arctic development hotspots
Projects in developing extraction of fossil fuels, such as oil and natural gas are underway in several places in the Arctic - both on land and in the sea. The fuels are to be transported by both land and sea pipelines, as well as shipped on water. The development of these activities threaten natural habitats, in hotspots for conservation and wildlife. This map displays some of the latest hotspots with current or proposed development, together wit...

The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) are presented in this figure, for the year 2090, with the surface temperatures over land, the size of the polar ice cap, and the outer limits of permafrost. This map features shipping routes in addition - as the sea ice is decreasing, the potential for developing shipping in the Arctic increases.

The Conservation of Arctic Flora and Fauna is a working group under the Arctic Council, for the countries of Russia, Denmark, USA, Canada, Sweden, Iceland, Norway and Finland and indigenous peoples. Monitoring, assessment, protected areas and conservation strategies are all tasks under this working group. The area that the working group primarily addresses is presented in this map.

Protected areas and wilderness Protected areas and wilderness
Wilderness areas in the Arctic, representing vast expanses of tundra and taiga that sees very little human disturbance and stress have been determined by an analysis prepared by the UN Environment Programme World Conservation Monitoring Centre in 2001. Overlaid with protected areas, this graphic highlights the areas that are currently not under International protection, and thus should be made a priority for conservation.

Ecoregions prioritised for conservation, in the Arctic (WWF Global 200) Ecoregions prioritised for conservation, in the Arctic (WWF Global 200)
Ecoregions represent large areas with geographically characteristic fauna, flora and climate - both marine and terrestrial. This graphic presents the ecoregion definitions identified by the World Wildlife Fund and associated experts, and specifically those ecoregions that have been designated as priority areas (Global 200 database) for conservation. This means that these ecoregions represent unique biodiversity characteristics, and also that ther...

Major wilderness areas in the Arctic Major wilderness areas in the Arctic
The Arctic covers around 33.5 million km2 and holds the largest continuous expanses of unfragmented wilderness in the world, outside of Antarctica. Indeed, seven of the ten largest wilderness areas in the world outside Antarctica are found in the high north. (UNEP/WWF 2001: 25 Largest Wilderness Areas in the Arctic). But in contrast with Antarctica, the Arctic is not uninhabited. Human cultures are and have been a part of these vast and rich ecos...

Pathways of contaminants to the Arctic 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 often referred to as long-range pollution or long-range transport of pollutants. While fear of these compounds sometimes has resulted in abandonment of traditional foods, this has also led to more unhealthy food habits acquired from non-indigenous pe...

Shift in climatic zones, Arctic scenario Shift in climatic zones, Arctic scenario
The scenarios from the Arctic Climate Impact Assessment (ACIA) project that temperatures will increase dramatically in the Arctic, more than in many other parts of the world. This leads to effects, such as the decrease of area (e.g. tundra) under continous permafrost, the northward move of the tree line and the decrease of Arctic Sea Ice. The synthesis is based on several different models and ensables and this map depicts the situation at the end...
