Thank you Mr. Asher for debunking the old submarine
at the North Pole myths. The subs used their SONAR to find a natural weak spot in the existing ice before they surfaced. There was ice at the pole when they surfaced. Now, thanks to polar amplified global warming there will be no ice at the North Pole.

Jason Mick (Blog) - June 30, 2008 Obviously Jason (and you) need to catch up on a wee bit of history where a nuclear submarine surfaced at the North Pole some time back around 1959 http://www.strangecosmos.com/content/item/131289.html HMS Sovereign took part in Operation Brisk during 1976. The submarine surfaced at the geographical North Pole as part of the exercise on 20th October 1976. Or just recently http://www.athropolis.com/news/submarines.htm. My advice is for you to use Google Obviously you (and the other skeptics here) need to catch up on a wee bit of oceanographic terminology. *The image of the Skate in 1959 clearly shows multi-year ice in the background (and very thick multi-year ice from the looks of it (with a huge pressure ridge in the distance)). *The image of the three subs from 1987 and the one from 1976 that someone else linked to on the John-daly.com website are similar, showing boats in leads. *All "subs at the N. Pole" images are of them surfacing in a refrozen lead, which is what they do. *They find a lead, or a recently frozen one and punch through it since they can't penetrate multi-year ice. *They do not show submarines surfacing at the north pole in open water. Open water to an arctic oceanographer is very different from leads in pack ice. *The explanation on John-Daly.com is about what you would expect, and is laughable when he explains "see those leads of open water?" *"Leads of open water" is an oxymoron to an oceanographer since you can't have leads in open water. *Open water is ice free. *Leads occur in pack ice. * If the N. Pole becomes open water (i.e., ice free, not leads in pack ice) this year, that is fairly different and should give you pause for a moment. *Unless of course, you are like John Daly and don't understand how dumb it is to say "leads of open water" or not recognize what that Skate image and the others really show. *My advice to you is to learn the difference because it is not semantic. * I know you are scared of climate change because like a lot of things you see it as taking away your core liberty of consumerism. *But that fear doesn't give you free reign to talk nonsense. * -- Bill Asher |

Roger: It is by no means certain the pole will be ice free, at least this year. However, if you google around you can find trends in multi-year ice coverage from IceSat (I think the string is something like "icesat multi- year trend" and it will dig out a powerpoint from the IceSat technical lead (no pun intended) at JPL). The decline in surface area coverage of multi-year ice is more remarkable than an ice-free pole, since a lot of the multi-year ice is grounded against Greenland and its areal extent is not so susceptable to variability. Here's an example: http://nsidc.org/images/arcticseaice...04_Figure6.png As an aside, one of the other things that can happen with multi-year sea ice is that the top part melts, forming a shallow lake. But since the ice is several meters thick there is still an underlying ice sheet. Some of the "leads" in the 1987 image in John-Daly.com (the one with the three subs) look to me like surface melt, not actual leads. But it's hard to tell from a single image taken at a slant. -- Bill Asher |
