Spatial distribution of vertical density and microstructure profiles in near-surface firn around Dome Fuji, Antarctica [PDF]

The Cryosphere
To better understand the near-surface evolution of polar firn in low-accumulation areas (<30 mm w.e. yr−1), we investigated the physical properties – density, microstructural anisotropy of ice matrix and pore space, and specific surface area (SSA ...

Aerial strip surveys of polar bears in the Barents Sea

, 1990
Aerial strip surveys of polar bears in the Barents Sea were performed by helicopter in winter 1987. The number of bears within 100 m on each side of the helicopter was counted. A total of 263.6 km2 was surveyed and 21 bears were counted.

Probing the firn refractive index profile using antenna response

Journal of Glaciology
The Radio Neutrino Observatory-Greenland (RNO-G, at Summit Station) experiment comprises an extensive fat-dipole antenna array deployed into ice boreholes over an eventual area of approximately 35 km2.

Late Pleistocene fossil find in Svalbard: the oldest remains of a polar bear (Ursus maritimus Phipps, 1744) ever discovered

, 2009
During recent fieldwork in Svalbard, a well preserved subfossil left mandible of a polar bear (Ursus maritimus Phipps, 1774) was discovered. A 14C age determination shows that it is older than 45 Ky (kilo-years), and an age determination with infrared ...

On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022

Western countries responded to the full-scale Russian attack on Ukraine on 24 February 2022 by imposing strong sanctions to isolate Russia. Norway has adhered to this policy, with exceptions for cooperation on border control, search and rescue, and ...
