Happy New Year 2024 (and sorry for the forum being offline some hours) /DM
Weather report as of 25 minutes ago (21:00 UTC):The wind was blowing at a speed of 6.2 meters per second (13.8 miles per hour) from East/Northeast in Tuktoyaktuk, Canada. The temperature was 15 degrees Celsius (59 degrees Fahrenheit). Air pressure was 1,018 hPa (30.06 inHg). Relative humidity was 54.8%. There were a few clouds at a height of 213 meters (700 feet), a few clouds at a height of 2438 meters (8000 feet) and broken clouds at a height of 6706 meters (22000 feet). The visibility was 24.1 kilometers (15.0 miles).
New Polar Portal with Sea Ice TemperaturesAug_09_2013Just launched this web site of Danish research institutions [-] displays the results of their monitoring efforts in the Arctic. New to me is the above composite of sliding mean temperatures captured by the Metop-A satellite. [hyphen added for clarity (I hope!)]
The Atlas is one of the outcomes of the project “The Northwest Passage and the construction of Inuit pan-Arctic identities” (funded by SSHRC—the Social Sciences and Humanities Research Council), and co-directed by Claudio Aporta (Marine Affairs Program, Dalhousie University), Michael Bravo (Geography, University of Cambridge), and Fraser Taylor (Geomatics and Cartographic Research Centre, Carleton University). This project looks at Inuit occupancy of the Northwest Passage, through a study and documentation of Inuit traditional trails and place names, which have interconnected Inuit groups across the Arctic since time immemorial.The two main research questions for this project are:1. how extensive and significant is the historical Inuit presence along the Northwest Passage? and2. how interconnected Inuit groups were before Europeans arrived?This Atlas focuses on historical written evidence of Inuit presence in most of the Canadian Arctic. It contains a selection of material obtained from hundreds of published and unpublished documents produced by explorers, ethnographers and other visitors who were in contact with Inuit during the early contact period or shortly before Inuit moved to permanent settlements. A very significant proportion of those trails and place names are still used today. The Atlas is a database, and the sources can be found through searches, or clicking on the features on the map. Each document has been given a geographic reference (which in some cases, it occupies the whole Canadian Arctic). Whenever possible Inuit place names and trails encountered in the documents were digitized separately.
Quote from: slow wing on April 17, 2015, 07:05:48 AMThat page is awesome! Thanks, Neven.EDIT: the whole site is awesome actually! You've done a lot of work on it since a few months ago?Thanks, slow wing. I update every few months, usually at the start of the melting season. The SLP patterns page was too much work (I figured Concentration maps is enough work already), which is why I've created the Forecasts page. I now only have to complete updating the Concentration maps page before the month is out, and then it's all set for the 2015 melting season.
That page is awesome! Thanks, Neven.EDIT: the whole site is awesome actually! You've done a lot of work on it since a few months ago?

Hi Neven, ... Is this the BBC scoop you were mentioning? :-)'3D Cryosat' tracks Arctic winter sea icehttp://www.bbc.com/news/science-environment-32348291
Yes, that's the scoop. CryoSat now has maps!
The ADS/vishop site now has a "Sea Ice Forecast" overlay feature. The images don't copy well to show here... go play with it on their page.https://ads.nipr.ac.jp/vishop/vishop-monitor.html?N...
The forecast maps aren't working for me on the Arctic Sea ice Graphs site right now, so I looked elsewhere.

Uploaded on Jul 29, 2011Time-lapse series of coastal bluff erosion along the Arctic Coast at Drew Point, Beaufort Sea, Alaska. Coastal erosion rates exceeding 20 meters per year are being observed along the Arctic Coast, and they are especially high along Alaska's Beaufort Sea coastline. Comparison of aerial photos and LANDSAT imagery suggest accelerating erosion rates over the last 50 years. Arctic sea ice coverage has been declining dramatically over the last few decades and record September minima were observed in 2007. These observations suggest a causal relationship between sea ice decline and coastal change. The timelapse movies presented here show that the relative roles of thermal and wave energy may be significant. The bluffs consist of silt and have high ice-content. The thawing of the ice-rich bluffs by relatively warm seawater undermines coastal bluffs, leading to topple failures of discrete blocks defined by ice-wedge polygons. The fine-grained nature of these materials does not function as a protective barrier for incoming waves, so there is not a strong negative feedback on erosion rates, so that coastal erosion rates in this setting are likely to increase with continued Arctic warming.Research Scientist, Irina Overeem, CSDMS, INSTAARUniv. of Colorado Boulder
And here is a very useful topographic map with glacier names etc.: http://toposvalbard.npolar.no/
Snow-capped mountain in Lambert Land. The name is one of a group of five given by the Place Name Committee for dogs used on the 1906-08 Danmark-Ekspeditionen. They replaced names suggested by John Haller. ‘Misanthropen' was an old and rather miserable dog which did not get on with the other dogs in the team.
After the Norwegian–Danish dispute over the sovereignty of parts of East Greenland was settled at the International Court of Justice in The Hague in 1933, the Place Name Committee for Greenland (Stednavneudvalget) was established, and the place names used on existing published maps of Greenland were systematically reviewed and with few exceptions approved in danicised form.More than 3000 place names were officially approved by the Place Name Committee for use in northern East Greenland up to the end of 1984, after which responsibility passed to the Home-Rule government at Nuuk in Green- land. More than a third of these place names were proposed by members of the expeditions led by the Danish geologist Lauge Koch. The post-war expeditions led by Lauge Koch were almost entirely geological in nature, and the place names given reflect in part geological characteristics of the features named, the animals encountered and events during the expeditions, as well as commemorating the mountains, lakes and other features of the home countries of the participants.
Terry,Those billboards were from the Heartland Institute, I recall, but your point is well taken.
Let there be maps....Modern day explorers from the Arctic nations of Canada, Denmark, Finland, Iceland, Sweden, Norway, Russia, and the United States are setting their sights north to map the seabed and establish sovereign rights to resources in an icy area that just over a decade ago was virtually inaccessible.http://coastguard.dodlive.mil/2016/11/mapping-the-extended-continental-shelf-in-the-arctic/
