So on a windy, sunny day in July, Hansen and an assistant visited experimental plots they had established in a high Arctic valley on the Advent fjord outside Longyearbyen.
A message in a bottle, buried 54 years ago under a rock cairn in a remote Arctic valley on Canada's northernmost island, could well be the last written words from a promising young glaciologist and explorer from Pasadena.
To demonstrate the value of historical glacier surfaces produced using oblique archive imagery, the reconstructed glacier surface topography is used to investigate evidence of a potential former surge front at the high-Arctic valley glacier, Austre Lovénbreen — a glacier identified to have potentially exhibited surge-type behaviour during the Neoglacial.
The study area was located in the high arctic Zackenberg valley in Northeast Greenland (74°30'N, 21°0'W).
The country has also acquired the paraphernalia of a tech cluster, such as a celebratory blog (Arctic Startup) and a valley-related name (Arctic Valley).
Almost all of Greenland's high-arctic landforms and biodiversity are represented in the valley, including moraines, scree slopes, rock glaciers, gently sloping rock faces, river beds, alluvial fans, a raised delta, beach terraces, permanent and perennial snow beds and glaciers, several types of ponds and lakes, fens, heath and barren lands, together with most known species of plants and animals.
The climate is high arctic, and the study area is mountainous with deep valleys and fjords.
This paper illustrates the usefulness of the vulnerability framework through three case studies: the tropical southern Yucatan, the arid Yaqui Valley of northwest Mexico, and the pan-Arctic.
Because Sakha, particularly the Lena valley, served as the main pathway to the arctic coast and, beyond that, America, during Paleolithic times [ 5], an understanding of its settlement history is important to elucidate the colonization of Northeast Eurasia as well as the peopling of the Americas.
One of the most recent snowy winters was 2008 09, when in the last two weeks of December cold temperatures from an arctic front that had just seeped its way into the lower mainland and the Fraser valley collided with moist air from the pacific; almost 100 cm of snow fell in Coquitlam, resulting in an extreme snow cover (over 50cms) for Christmas and resulted major traffic and flight issues.
Three regional changes, if accompanied by vegetation redistribution, represent biome shifts: complete loss of climate conditions for arctic tundra in northern Yukon; emergence of climate conditions supporting grasslands in southern Yukon valleys; reduction in climates supporting alpine tundra in favor of boreal forests types across the mountains of central and northern Yukon.
