Talk:Antarctic ice sheet

message: If Antarctica is 5.4 million square miles and contains 6.4 million CUBIC miles of ice, this implies the ice is on average over a mile deep. But according to bedrock elevation maps, such as this one: http://nsidc.org/data/atlas/news/bedrock_elevation.html, this is not the case. Here is a cite that states that antarctic ice averages to be about 3 to 6 feet thick: https://nsidc.org/cryosphere/seaice/characteristics/difference.html. Am I missing something? Perhaps there is a typo and the correct measure is actually 6.4 million SQUARE miles of ice?  — Preceding unsigned comment added by 96.82.57.209 (talk) 20:03, 2 March 2017 (UTC)

thread_title:  Numbers that don't add up ? 

message: The article says, "Recent satellite data reported by NASA shows evidence that the total amount of ice in Antarctica has increased in the past few decades."  However that data is now about four and a half years old (from August, 2002,) so it is hardly "recent."  Also, more recent data suggests that the Antarctic ice sheets are actually melting now.  See "Antarctic Ice Sheet Is Melting Rapidly" and "Antarctic ice sheet losing mass, says University of Colorado study" from March, 2006.  Do we have an expert who can update this?  If not, I'll do it, but I thought I'd check first. -- HiEv 12:12, 7 January 2007 (UTC)
replies: text: Wikipedia doesn't need experts to update articles.  Measuring the net gain or loss of ice over an entire continent is not an easy thing to do, even with satellites.  The article should reflect the fact that these are individual studies, each of which is saying something slightly different.  Such is science.  But feel free to update the article yourself. -- BlueCanoe 01:52, 24 August 2007 (UTC)
thread_title:  "Recent" studies 

message: Where is the article on the East Antarctic Ice Sheet?  The West Antarctic Ice Sheet has its own article, and rightly so.  The two "halves" of the Antarctic Ice Sheet are very different from each other with respect to geography, origin, age, stability, climate, etc.  If I get time I'll start the article but anyone else should go for it! -- BlueCanoe 01:52, 24 August 2007 (UTC)
thread_title:  East Antarctic Ice Sheet 

message: This article states that because the density of freshwater ice is different from saltwater, the ocean levels will still rise if the floating ice melts. However, my understanding is that the effect on ocean levels depends not on the density, but on the weight of the ice or water, and how much seawater that weight of ice displaces. My understanding is thus that it doesn't matter how dense freshwater is compared to saltwater. Is this the case? Eunsung (talk) 02:01, 22 January 2009 (UTC)
replies: text:  I'm willing to believe anyone who knows what the hell they're talking about, haha. If that's you, could you edit the article with a clear explanation about this, or maybe take away the comment on the matter entirely? Cheers. Eunsung (talk) 05:38, 23 January 2009 (UTC)
thread_title:  Ice Density and Ocean Levels 

message: I would like to suggest removal of this paragraph based on the comments above. In doing so the similar section on the ice shelf page (where this information is better placed) should be beefed up a bit. Any thoughts. I will leave it for a while Polargeo (talk) 14:44, 28 January 2009 (UTC)
thread_title:  Ice density section removal 

message: I actually don't think that the prominance of recent melt and warming on this page, including two images is particularly helpful. It gives the impression that this is in some way affecting the whole mass balance of the Antarctic Ice Sheet. It is not. At present changes in surface temperature are tiny and have negligable effects on the ice sheet. It sends a confusing message. There are many more important factors at work on the ice sheet at present. That big red blob in the warming image over West Antarctica represents around 1 degree over half a centuary, with average temperatures in this region somewhere between -20 and -30 degrees. Then add on the melt image which just repesents the small amount of surface melt Antarctica experiences (Mostly a mere glazing of the ice surface). This melt does not reach the base of the ice sheet, does not run off into the sea and has no direct effect on the movement or mass balance of the ice sheet. Therefore this page, whilst not being inaccurate, is simply getting confusing to the general public and needs more balance.  Polargeo (talk) 13:27, 20 February 2009 (UTC)
thread_title:  Warming 

message: Suddenly talking about sea ice makes it confusing that this is distinct from the ice sheet if the reader is not familiar with the terms.
I think that this needs to be prefaced with a sentence about what an ice sheet is, or moved to it's own section about sea ice. RobinGrant (talk) 04:59, 16 October 2013 (UTC)
replies: text: Right. These are often confused. For example, this Forbes article The Antarctic Ice Sheet Is Growing, But It Doesn't Mean Global Warming Isn't Real. The definition in the introduction should explain the distinction between (floating) sea ice and (grounded) ice sheet. Keith McClary (talk) 15:36, 30 October 2016 (UTC)
