Sentences with phrase «sea ice deformation»

A combined lack of coherence in ice drift fields and reduced ice concentrations in April 2011 relative to April 2007 suggest that springtime ice dynamical contributions to fall sea ice extent may be associated with sea ice deformation and ridging within an increasingly mobile and fractured ice cover.

''... sea ice deformation, ocean eddies, and associated ice - ocean boundary layer mixing, multiphase clouds as well as land - atmosphere - ice - ocean interactions.»

The neXtSIM model is currently being developed at the Nansen Environmental and Remote Sensing Center, and is unique among sea ice models owing to its rheological framework that is based on solid mechanics and allowing to reproduce the multifractal scaling invariance of sea ice deformation with an unprecedented realism.

Sentinel - 1A / B operate a synthetic aperture radar (SAR) with advanced observation capabilities in all weather conditions over the ocean (wind, waves, and surface current) and sea ice field (sea ice deformation, lead fraction and sea ice drift).

Furthermore, dissimilarity and a continued loss in coherence in sea ice drift patterns in March 2012 relative to March 2007 and 2011 suggests that spatiotemporal variability in fall ice extent will be governed by local ice conditions and ice - ice interactions as monitored by small - scale properties associated with sea ice deformation.

Advancing the knowledge on the effects of sea ice deformations on upper ocean stratification and ecosystem will have profound implications on our ability to forecast ongoing changes in Arctic Ocean.

Sea ice deformations also impact melting and freezing in leads, ridging and sea ice circulation, which are key players in determining sea ice mass balance and age, and freshwater mass distribution in the Arctic Ocean.

«We found that the Antarctic ice sheet had an uneven effect on the global sea level because its growth resulted in a complex interplay between gravitational and rotational effects and the deformations to Earth's crust caused by ice advance and retreat,» he says.

The sea ice component represents sea ice in multiple categories of thickness and accounts for changes in thickness due to growth and melt as well as mechanical deformation of ice (Thorndike et al. 1975, Hibler 1980).

And may I add looks remarkably similar to the idealized deformation of the polar vortex under scenarios with Arctic warming, low Arctic sea ice and increased Siberian snow cover presented in my recent review paper with Jennifer Francis [of Rutgers University].

To assess these implications, we translate global into local SLR projections using a model of spatial variation in sea - level contributions caused by isostatic deformation and changes in gravity as the Greenland and Antarctic ice sheets lose mass (36 ⇓ — 38), represented as two global 0.5 ° matrices of scalar adjustment factors to the ice sheets» respective median global contributions to SLR and (squared) to their variances.

The Arctic Oscillation and North Atlantic Oscillation influence substantially the drift and deformation of the sea ice, which is of equal importance in the seasonal evolution of sea ice ice extent.

Secondary objectives: Four secondary objectives have been defined: - To assess the effect of a more accurate simulation of sea ice drift and deformation on the Arctic sea ice mass balance and distribution properties of sea ice age.
