Record #196269:

Variability and changes of Arctic sea ice cover, 1975-2000 / Annu Oikkonen.

Title: Variability and changes of Arctic sea ice cover, 1975-2000 / Annu Oikkonen.
Author(s): Oikkonen, Annu.
Date: 2008.
In: University of Helsinki. Department of Geophysics. Report Series in Geophysics. (2008.), Vol. 56 (2008)
Abstract: Describes thermodynamic and dynamic influences on ice thickness and presents comprehensive overview of average conditions, variability, and changes of Arctic Ocean, sea ice and climate. Determines ice thickness from submarine-derived ice draft data in North Pole, Canada Basin, Beaufort Sea, Chukchi Cap, Eastern Arctic, and Nansen Basin regions. Identifies widespread thinning, greatest where ice was initially thickest (reducing regional variation) and stronger in spring than in autumn (reducing seasonal variability). Nansen Basin saw small changes. Autumn mean draft increased by 0.2 m in Chukchi Cap. Strongest and most uniform change was replacement of thick, mostly deformed ice by younger ice. Draft distribution in Beaufort Sea changed from perennial to seasonal ice zone type.
