Characteristics of the Arctic Ocean''s Beaufort Sea high are examined using fields from the NCEP--NCAR reanalysis. At a 2-hPa contour interval, the Beaufort Sea high appears as a closed anticyclone in the long-term annual mean sea level pressure field and in spring. In winter, the Beaufort...

The Sheltie hails from the rugged Shetland Islands, which lie between Scotland and Norway, about 50 miles north of Scotland and a bit south of the Arctic Circle. These islands are also home to other small breeds of animals, such as Shetland Ponies and Shetland Sheep. For many years, the ...
During summer, cyclonic activity remains common in the same regions as observed for winter, but increases over Siberia, the Canadian Arctic Archipelago and the Central Aretic, related to cyclogenesis over northern parts of Eurasia and North America. Eurasian cyclones tend to enter the Aretic Ocean...
Arctic ground squirrels, Citellus undulatus, produce six distinctly different sounds. Each of these sounds may represent a signal in itself, but combinations of these acoustic elements or repetition of a single element produce additional signals. Several of these signals serve as alarm calls. One sou...
Sea ice data derived from the Scanning Multichannel Microwave Radiometer are examined for sections of the Arctic Ocean during early summer 1979. The temporary appearance of spuriously high multiyear ice fractions in the seasonal ice zones of the Kara and Barents Seas is a result of surface melt ...
Skillful Arctic sea ice forecasts may be possible for lead times of months or even years owing to the persistence of thickness anomalies. In this study sea ice thickness variability is characterized in fully coupled GCMs and sea ice-ocean-only models (IOMs) that are forced with an estimate of...

It was found that the time air resides continuously north of 70°N, called its Arctic age, is highest near the surface in the North American sector of the Arctic. North of 80°N and near the surface, the mean Arctic age of air is about 1 week in winter and 2 weeks in summer. It...
