TLDR
In this paper, a comparison of sea-ice draft data acquired on submarine cruises between 1993 and 1997 with similar data acquired between 1958 and 1976 indicates that the mean ice draft at the end of the melt season has decreased by about 1.3 m in most of the deep water portion of the Arctic Ocean, from 3.1 m in 1958-1976 to 1.8 m in the 1990s.Abstract:
Comparison of sea-ice draft data acquired on submarine cruises between 1993 and 1997 with similar data acquired between 1958 and 1976 indicates that the mean ice draft at the end of the melt season has decreased by about 1.3 m in most of the deep water portion of the Arctic Ocean, from 3.1 m in 1958–1976 to 1.8 m in the 1990s. The decrease is greater in the central and eastern Arctic than in the Beaufort and Chukchi seas. Preliminary evidence is that the ice cover has continued to become thinner in some regions during the 1990s.read more

TL;DR: In this paper, the authors analyzed the results of fourteen global ocean-sea ice models in the framework of the Coordinated Ocean-ice Reference Experiments, phase II (CORE II).

TL;DR: It is suggested that semi-closed fjords may be less susceptible to this type of environmental variability, and that communities are shaped by an interaction of impacts from local topography, glacial runoff, local circulation patterns, and faunal life-history traits.

Large Scale Characteristics and Variability of the Global Sea Ice Cover
TL;DR: More than two decades of satellite passive microwave data are used to study and evaluate the large scale characteristics and the changing state of the sea ice cover in both the Northern and Southern Hemispheres as discussed by the authors.

TL;DR: For example, this paper found that the model ensemble mean trend over the period of instrumental records is smaller than observed, and there is evidence that the rate of decline has accelerated during the last decade.

Variability of Fram Strait ice flux and North Atlantic Oscillation
Ron Kwok,D. A. Rothrock +1 more
TL;DR: In this paper, the authors estimated the winter sea ice export through the Fram Strait using ice motion from satellite passive microwave data and ice thickness data from moored upward looking sonars, and found a significant correlation between the area flux and positive phases of the North Atlantic Oscillation (NAO) index over the months of December through March.
Journal ArticleDOI
Recent decreases in Arctic summer ice cover and linkages to atmospheric circulation anomalies
TL;DR: In this article, the authors show that summer ice coverage has been below normal in recent years, with extreme minima in 1990, 1993, and 1995, and linkages are proposed between these ice anomalies and a sharp increase since 1989 in the frequency of low pressure systems over the central Arctic.

Warming of the Arctic Ocean by a strengthened Atlantic Inflow: Model results
TL;DR: In this article, an ice-ocean model is used to examine the behavior of the Arctic Ocean in response to recent changes in Arctic climate, and the model shows that, starting about 1989, there has been a significant warming and salinification in the Arctic ocean, in agreement with recent observations.

Evidence for thinning of the Arctic ice cover north of Greenland
TL;DR: In this paper, a British submarine carried out an ice profiling experiment in the Arctic Ocean in which the route closely approximated that of an earlier voyage in October 1976, and there is evidence of a significant decrease in mean ice thickness in 1987 relative to that found in 1976.
Journal ArticleDOI
A toy model linking atmospheric thermal radiation and sea ice growth
TL;DR: In this paper, a simplified analytical model of sea ice growth is presented where the atmosphere is in thermal radiative equilibrium with the ice, making the downwelling longwave radiation reaching the ice surface an internal variable rather than a specified forcing.
