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

Arctic Ocean during the Last Glacial Maximum: Atlantic and polar domains of surface water mass distribution and ice cover
Niels Nørgaard-Pedersen,Niels Nørgaard-Pedersen,Robert F Spielhagen,Helmut Erlenkeuser,Pieter Meiert Grootes,Jan Heinemeier,Jochen Knies +6 more
TL;DR: In this paper, the authors used 52 sediment cores, analyzed and dated at high resolution, to reconstruct the last glacial maximum (LGM) for the Fram Strait and the eastern and central Arctic Ocean.

The impact of climate change on child health.
TL;DR: The role of climate change on child health is discussed and 3 ways in which this relationship may manifest are suggested, including directly cause heat stroke, drowning, gastrointestinal diseases, and psychosocial maldevelopment.

The sea ice mass budget of the Arctic and its future change as simulated by coupled climate models
TL;DR: In this paper, the authors assessed the changes in Arctic sea ice mass budgets for the twentieth century and projected changes through the twenty-first century from 14 coupled global climate models and found that the changes were strongly related to variations in absorbed solar radiation, due in large part to differences in the surface albedo simulation.

An Improved CryoSat-2 Sea Ice Freeboard Retrieval Algorithm Through the Use of Waveform Fitting
TL;DR: In this paper, an empirical model capable of simulating the mean echo power cross product of CryoSat-2 SAR and SAR In mode waveforms over sea ice covered regions is developed.

Arctic Ocean sea ice volume: What explains its recent depletion?
D. A. Rothrock,Jinlun Zhang +1 more
TL;DR: In this article, the authors decomposed the arctic sea ice volume into two components: a dynamic or wind-forced response to interannually varying winds but a fixed annual cycle of air temperature and a thermally forced solution responding only to the interannual varying temperatures.

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.

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.
