However, they emphasize the importance of ice cover over other attributes in the total system.
NSIDC reports ice extent, a two-dimensional measure of the Arctic Ocean’s ice cover. But sea ice extent tells only part of the story: sea ice is not all flat like a sheet of paper....Scientists want to know not just how far the ice extends, but also how deep and thick it is, because thinner ice is more vulnerable to summer melt.

Exactly what are you gleaning out of this report

Since I referenced much of the entire website.
Your link just mentions how scientists are attempting to more accurately measure ice thickness.
Nothing in your link supports your claim that they feel that thickness is a more important attribute than extent.
Could it just be wishful thinking on your part?

The discussion here is related to Arctic sea ice, not to Antarctic land ice. GRACE has been and still is mentioned in many threads, such as the Ice Apocalypse - MULTIPLE METERS SEA LEVEL RISE thread.

Sorry...as I said, I thought this was the best place for it.
