the south - bound expedition had cleared that vast plain of floating ice which flows down from the great mountains of the interior and covers the southern part of Ross Sea throughout an area above 20,000 square miles with an ice sheet approximately 800 feet in thickness, and had begun to climb the heights which form the mountainous embayment at the head of Ross Sea.

Scientists still have a great deal to learn about the ice cover around the North Pole, not least about the full meaning of the thickness of sea ice.

This thicker multiyear ice takes longer to melt back (both because of greater thickness and higher albedo than first - year ice) and so in conjunction with the weather it is responsible for more extensive ice in the late summer in this region.

The empirical evidence from the past two decades reveals that declining sea ice cover and thickness have been great enough to enhance Arctic warming during most of the year.

The ice in the central Arctic Ocean in April during this years North Pole Environmental Survey (NPEO) deployment was again dominantly first year ice, but seemed more deformed than usual suggesting greater average thickness, a positive factor in extent.

Recent research indicates it may be related to increasing friction at the base of the ice sheets slowing ablation and allowing greater thicknesses.

Since 1950, Arctic sea ice has lost half its area and half its thickness, helping to cause the phenomenon of Arctic amplification − the greater temperature rise (approaching 3 °C) observed in the Arctic than anywhere else on Earth.

Asia's mountain ranges contain the greatest thickness of ice beyond the polar regions.

Ice thickness is more difficult, and I would assign greater error bars, but the increase is quite remarkable, and, as Willis recently pointed out, while the exact m = thickness may be disputable, the method used is consistent, therefore the change documented is true relative to the past, even if the exact value is not known.

Hank, that is a great paper and it shows that decreasing ice thickness is making it harder to forecast the next season's extent.
