In the atmospheric science literature, the term polar vortex is most commonly used as an abbreviation for circumpolar
vortex and refers to a planetary-scale westerly (west to east) flow that encircles the pole in middle or high latitudes.
The next most recognisable circumpolar
constellation is Cassiopeia.
Our home in the circumpolar
world, Inuit Nunaat, stretches from Greenland to Canada, Alaska and the coastal regions of Chukotka, Russia.
Section 1 covers the first Arctic wave--the end of the Cold War, circumpolar
cooperation, and regional cooperation.
The dominant southern current is the Antarctic Circumpolar
A recent trip to Iceland as part of the Institute of the North's Iceland Policy Tour allowed four University of Alaska Fairbanks students to explore energy technology and policy question through the lens of another circumpolar
The remains of an umiak discovered among a recent acquisition at the University of Alaska Museum of the North have been dated at 1,000 years old, the oldest skin boat assembly in the Circumpolar
An open letter from the Climate Change Adaptation Research Group (CCARG) to the Honourable Leona Aglukkaq, MP for Nunovut and federal Minister of Health as the new chair of the Arctic Council calls for an inclusion of "the realities and impacts of climate change in the North" in the mandate of environmental, social and economic development of the circumpolar
Amongst the surveyed species it is worth noting the discovery of the liverwort Scapania cuspiduligera, a new record for Albania; this is a Circumpolar
Boreo-Arctic montane species, very rare in the Mediterranean area where it only occurs in Spain, France and Italy, while the old records for Slovenia and Greece are still to be confirmed (Ros & al.
Simon's distinguished career has been devoted to advancing sustainable and equitable development in the circumpolar
Among these, the northern pike (Esox lucius) is circumpolar
and believed to consist of a single species.
Here is a letter written to the British Admiralty: "A considerable change of climate, inexplicable at present to us, must have taken place in the Circumpolar
Regions, by which the severity of the cold that has for centuries past enclosed the seas in the high northern latitudes in an impenetrable barrier of ice has been, during the last two years, greatly abated.
Eventually, the iceberg will move further north; it will be picked up by wind and ocean currents - and the primary ocean current there is the Antarctic Circumpolar
Increased mixing in the Pacific and Indian oceans during glacial periods could have increased the amount of water moved by the Antarctic Circumpolar
Current by about 30 percent, the authors suggest.
New research published in the journal Science, led by Rensselaer Polytechnic Institute scientist Miriam Katz, is providing some of the strongest evidence to date that the Antarctic Circumpolar
Current (ACC) played a key role in the major shift in the global climate that began approximately 38 million years ago.
