Sentences with phrase «changes in sea ice thickness»

Maslowski's recent, peer - reviewed work (Maslowski W., Clement Kinney J., Higgins M., Roberts A. (2012) «The Future of Arctic Sea Ice», The Annual Review of Earth and Planetary Sciences, 40: 625 - 654) emphasizes «the need for detailed analyses of changes in sea ice thickness and volume to determine the actual rate of melt of Arctic sea ice».

Not exact matches

Although CryoSat - 2 is designed to measure changes in the ice sheet elevation, these can be translated into horizontal motion at the grounding line using knowledge of the glacier and sea floor geometry and the Archimedes principle of buoyancy — which relates the thickness of floating ice to the height of its surface.

From an altitude of just over 700 km, CryoSat will precisely monitor changes in the thickness of sea ice and variations in the thickness of the ice sheets on land.

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).

The magnitude and spatial distribution of the high - latitude climate changes can be strongly affected by sea ice characteristics, but evaluation of sea ice in models is hampered by insufficient observations of some key variables (e.g., ice thickness)(see Section 4.4).

Although CryoSat - 2 is designed to measure changes in the ice sheet elevation, these can be translated into horizontal motion at the grounding line using knowledge of the glacier and sea floor geometry and the Archimedes principle of buoyancy — which relates the thickness of floating ice to the height of its surface.

On the text on the extent of Arctic sea ice, the UK asked about changes in Arctic sea ice thickness and the US about summer sea ice extent, to which the CLAs replied that this information is discussed in detail in the underlying assessment.

Stéphanie Jenouvrier, a biologist at the Woods Hole Oceanographic Institution in the US, and colleagues from France and the Netherlands report in Nature Climate Change that changes in the extent and thickness of sea ice will create serious problems for a flightless, streamlined, survival machine that can live and even breed at minus 40 °C, trek across 120 kilometres of ice, and dive to depths of more than 500 metres.

THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing oceans).

Sea ice thickness and spatial extent change rapidly in response to seasonal changes and in response to longer - term climate changes.

Changes in sea ice extent, timing, ice thickness, and seasonal fluctuations are already having an impact on the people, plants, and animals that live in the Arctic.

Our results stress the importance of considering loss of sea ice thickness in future climate change assessments.

The modeled evolution of Arctic sea ice volume appears to be much stronger correlated with changes in ice thickness than with ice extent as it shows a similar negative trend beginning around the mid-1990s.

Projected changes in climate should produce large reductions in the extent, thickness, and duration of sea ice.

As such, monitoring Arctic ice thickness may be useful for predicting rapid changes in sea ice.

Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.

And scientists from NASA recently flew a series of missions over the Arctic during the IceBridge project, to study details of Arctic sea ice thickness as well as changing glaciers in Greenland.

Global Climate Change Record 10 - 19 % Declines Seen in Arctic Sea Ice Thickness Last Winter, Satellite Data Reveals Argentine Glacier (Perito Moreno) Breaks in Winter for the First Time Ever OK Grasshopper, This Is What You SHOULD Have Done to Prepare

Trends in sea ice thickness / volume are another important indicator of Arctic climate change.
