If we compare the ice thickness map of the previous winter with that of 2012, we can see that the current ice conditions are similar to those of the spring of 2012 — in some places, the ice is even thinner,» Dr Marcel Nicolaus, sea ice physicist at AWI, said today at a press conference during the EGU General Assembly in Vienna.

Examining the CyroSat - 2 sea ice thickness map for this spring, Stefan Hendricks further explained: «The Transpolar Drift Stream, a well - known current in the Arctic Ocean, will be carrying the majority of the thick, perennial ice currently located off the northern coasts of Greenland and Canada through the Fram Strait to the North Atlantic.

However, as you'll see by the sea ice thickness maps below, there may be good reason for the lack of ringed seal lairs, and a general lack of seals except at the nearshore lead that forms because of tidal action: the ice just a bit further offshore ice looks too thick for a good crop of ringed seals in all three years of the study.

Developing an understanding of how ice sheets are changing over time requires precise measurements of the thickness of the ice sheets and accurate mapping of the bedrock below.

The study uses data from two NASA missions — Operation IceBridge, which measures ice thickness and gravity from aircraft, and Oceans Melting Greenland, or OMG, which uses sonar and gravity instruments to map the shape and depth of the seafloor close to the ice front.

The results, in the October 15 Science, agree with theoretical predictions, suggesting that superconducting gravimeters can help satellites chart the earth's gravity to map changes in polar ice cap thickness, seawater levels, atmospheric density and planetary geology.

After compiling 10 floe - scale maps of the ice from the Weddell, Bellingshausen, and the Wilkes Land regions of the continent, the researchers found that the sea ice thickness tended to be highly variable, with many ridges and valleys, they report online today in Nature Geoscience.

For six weeks the researchers collected radar data to map changes in ice shelf thickness to understand the processes that contribute to melting at its base.

«At Kima'Kho, we were able to map a passage zone in pyroclastic deposits left by the earliest explosive phase of eruption, allowing for more accurate forensic recovery of paleo - lake levels through time and better estimates of paleo - ice thicknesses,» says UBC volcanologist James K Russell, lead author on the paper published this week in Nature Communications.

So what we need is detailed topo maps of the bed and thickness of the GIS, and to work out a map of the «net buoyancy», or some such (i.e. total ice area density subtracted from the area density of a hypothetical column of water resting on the bed and extending up to sea level).

Just thinking out loud (and I only know enough to be dangerous;), but with IR radiation mapping during winter, one might be able to infer a sub-surface temperature profile and compare that with mass loss and ice sheet thickness.

Kids can even create their own data visualization by coloring in a map showing ice thickness on Greenland.

A goal for accurate summer forecasts should be an accurate map of ice type, age, thickness distribution, and ridging at the end of winter.

Buoys provide key observations for mapping and attributing summer ice loss: drift, bottom vs. top melt, amount of snow accumulation, nature of ponds (even if anecdotal from web cams), and thickness of level ice.

To determine how much ice and snowfall enters a specific ice shelf and how much makes it to an iceberg, where it may split off, the research team used a regional climate model for snow accumulation and combined the results with ice velocity data from satellites, ice shelf thickness measurements from NASA's Operation IceBridge — a continuing aerial survey of Earth's poles — and a new map of Antarctica's bedrock.

As surface temperture is altitude dependent one might have thought the first thing to check would be a map, as the arctic ice lies at sea level + 9 % of its thickness, while the antarctic ice sits several kilometers high in the sky, and the surrounding apron of the stuff is immune to windage because of the circumpolar continent in its midst.

This SMOS thickness map reveals how thin the recently refrozen sea ice on the Atlantic side still is:
