message: I believe the word should have been left as "calve" - a process for pieces of ice to break off in analogy with a cow having calves.  The page is so big I cannot find where to edit, though; when I open an edit window - my screen search does not work inside an editing window.

replies: text: Hmpf. Drift ice has resurrected itself. I've re-instated the merge proposal William M. Connolley 09:25, 7 November 2006 (UTC)
replies: text: Oppose merge. ("resurrection": Didn't you know that drift ice is a seasonal phenomenon in many places? :-) I resurrected it, not it itself. Of course, initially it was a naive 5th-grader level text.  But I intend to expand it. It is a huge well-defined subtopic of equally huge topic of sea ice, no reason to merge. In wikipedia big articles are split into smaller ones, not vice versa. Since we are at this, why don't you suggest to merge Iceberg here too? `'mikkanarxi 02:34, 8 November 2006 (UTC)
replies: text:  Because sea ice is simply the same thing as drift ice. Sea ice is seasonal, too. What exactly is the distinction between SI and DI? William M. Connolley 09:44, 8 November 2006 (UTC)
replies: text:  "Seasonal" was a joke in response to your "resurrected". Sea ice is either drift ice or fast ice. Of course, the overwhelming majority of sea ice is Arctic and Antarctic ice packs, but still pack ice is but a type of sea ice. `'mikkanarxi 22:51, 13 November 2006 (UTC)

text: You still fail to understand my poit: "fast ice" is not another name for sea ice. It is another type of sea ice, just as timber is not the same as wood (calling a shovel a spade...). The whole ice topic is somewhat understructured, as I see. For example, do you know where in wikipedia is written what type of ice is iceberg? `'mikkanarxi 23:05, 13 November 2006 (UTC)

text: And I would agree that from the point of view of formation they are basically the same. But they have differences in many external respects. `'mikkanarxi 23:07, 13 November 2006 (UTC)

text: Right now unfortunately I don't have time to sit and put these ice issues in order. `'mikkanarxi 23:09, 13 November 2006 (UTC)

text: As a final stroke, I apologize for possibly appearing as a layman asshole to you, since you surely know things here. But we laymen have a bit different perspective. `'mikkanarxi 23:27, 13 November 2006 (UTC)
thread_title:  Merge proposal 

message: I removed the animation of sea ice fluctuation around a year. 
REASON: it contained at least one severe error. It was not just a bit inaccurate, but coarsely. The animation shows the whole of Norwegian Sea freezing, which simply does not happen. Even during the coldest years of the so-called Little Ice Age the limit of sea ice was around 72 deg North latitude in Barents Sea, and the middle and eastern portions of Norwegian Sea, thus including the coast of Norway, were ice free year-round. 
I assume the animation depicts such an ice situation that has most recently happened approximately 10 000 years ago, during the last Ice Age proper. Greetings from Finland (that is near Norway). 80.221.61.8 19:12, 29 May 2006 (UTC)

message: The folk etymology given for fast ice as ice that has fastened to land is questionable. Fastland is Swedish for a large land mass, as opposed to a skerry or other small island; modern Swedish lies much closer to Old English (or Old Norse) than does modern English. Swedish fast has other uses and it's nearest equivalent might be the English phrase, hard and fast. — Robert Greer (talk) 20:47, 28 August 2008 (UTC)
thread_title:  fast ice 

message: Seems incorrect to have ice floes redirect to this article if it implies seawater (salinity). It occurs regularly during the winter months in the fresh water of the Great Lakes...see Spectacle Reef Light. The word "seawater" is at odds with "freshwater" and these forms of ice apply to both. Drift ice can also be freshwater.⋙–Berean–Hunter—► ((⊕)) 23:28, 30 October 2008 (UTC)

thread_title:  references getting stale 

message: I took out:
: The subtle climatic effects of the 11-year sunspot cycle can be detected in the ice extent data, as well as longer term solar output cycles like the 88-year Gleisberg cycle (see Solar Variation)which was at it's coolest point in 1986.  Because there were no satellites in orbit earlier than 1978, any conclusions regarding long-term trends must take into account natural cycles in solar energy output which may have been at their lowest points at the beginning of satellite reconnaissance technology.  At the warmest part of the 11-year sunspot climate cycles, like the winter of 2005-2006, sea ice is observed to reach a winter maximum extent that is smaller than in the years before or after.  Because first-year sea ice is more prone to melting during the following summer season, there is often a one- or two-year lag observed in the corresponding minimum summer sea ice before the cooling half of the climate cycle can be detected as greater ice extents in the summer seasons.
I don't think it is true; there are no refs; and I couldn't see anything relevant in the solar variation article. Also, it doesn't belong under "monitoring"; it is really talking about long term trends William M. Connolley (talk) 17:22, 11 July 2010 (UTC)

message: The data shown is the sea ice extent graph is quite wrong. I'm not sure where it came from but here is the actual sea ice extent and it is nothing like that presented on this page. http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg I suggest if there is no a suitable clean graph for use (suggestions anyone) that it should be deleted in the interests of accuracy.

replies: text:  That's a different picture, indeed. I'm not quite sure of your point. BTW, the pic in the article is ice volume, not area or extent William M. Connolley (talk) 07:33, 18 April 2013 (UTC)
replies: text: Sorry I though the point was clear. The existing graph is dominated by a hindcast from an unproven computer model (which is not in the given reference so I don't know where it came from anyway so it violated WP:VER). The red measured data covers year or so. Now it is accepted that ice area is most important in terms of radiative balance (an idea I'm sure you know well) so area is the measure of interest for the article and the graph I linked shows the historical data from a reputable source. I'd say this is more valuable than an unproven computer model (unproven because it seems to fit only a few years and quite poorly)... So, do you agree with the value/benefit of putting up actual data? MarkC (talk) 21:14, 18 April 2013 (UTC)
thread_title:  Sea ice extent graph wrong- new one? 

message: I think this article should make clear in writing or with maps the regions which are especially prone to sea ice.  All the text mentions is the Arctic and Southern seas.  Having lived in Estonia and Finland I remember that sea ice occurs every winter and ice breakers have to be used to carve shipping channels.  This made me wonder how much of the Baltic sea freezes and how much of other seas freeze and how often.  It would be nice if this article went into more detail about these things.--XANIA - ЗAНИAWikipedia talk |  Wikibooks talk 12:06, 5 September 2014 (UTC)

message: Is it possible to have - and thus to develop - a kist of classifications of polar and sea ice, which would show the kinds of knowledge and analyses of that ice?
We see:
:"Another classification used by scientists to describe sea ice is based on age, that is, on its development stages. These stages are: new ice, nilas, young ice, first-year and old."
That could be a start... MaynardClark (talk) 19:39, 22 November 2016 (UTC)

message: The section on Monitoring and Observations states:
"The volume of ice hit an all-time low in September 2012, when the ice was determined to cover only 24% of the Arctic Ocean, offsetting the previous low of 29% in 2007. Future predictions cast that summer sea ice might disappear altogether as soon as 2020.[12] "
The reference used dates back to 2012. It is now 2018. Is arctic summer sea ice still predicted to disappear by 2020?
