Sitatbeesaman says: April 27, 2012 at 2:02 am My paying job involves me teaching MAST (Maths and Science teaching) in a leading UK teaching university, but for my own pleasure I also study history. To the point where after my Science degree I carried on and took another in History. As part of this interest I must confess I love pouring over old maps and one of the cartographers that caught my eye recently was August Heinrich Peterman. I love the comments he, or his collaborators, added to his maps.For example his map of the Arctic in 1852 reproduced here:http://www.lindahall.org/events_exhib/exhibit/exhibits/ice/39_img1.shtml(courtesy of the Linden Hall Library)Note at the top of Baffin Bay around Parry Island it says "Open sailing ice March 1851."Or between the Laptev and Kara Seas it says "Open water March and April."There are more of these notes, pointing out open sea and no ice, dotted around the map.Of course it could all be a set up by that well know skeptical institution the British Admiralty of the 1850s. Or it could be more historical evidence that the Arctic ice was not as thick and extensive as certain people would like us all to believe. But I'm sure they have a model somewhere that can explain it away.
SitatA paper published today in Geophysical Research Letters finds that Arctic sea ice extent is controlled by low-level winds which regulate the flow of ice through the Fram Strait.
