Available in PDF, EPUB and Kindle. Book excerpt: The Fort Greely area in the interior of Alaska is especially interesting because it has such a wide variety of snow types. It contains the low density snow, consisting mostly of depth hoar, which is typical of wind sheltered valleys. It also has hard windpacked snow in unforested places because of the prevalence of strong winds from Isabell Pass in the Alaska Range. The snow structure evolves through the winter in different ways, depending on exposure to wind and to temperature gradients in the snow. The effect of snow structure on vehicle traffic is extremely variable from place to place. This is documented by measurements of density, temperature, and ram hardness together with 21 photographs and 9 line drawings.
Download or read book A Winter Environmental Data Survey of the Drainage Basin of the Upper Susitna River Alaska written by Michael A. Bilello and published by . This book was released on 1980 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic data on the winter climate and measurements on all available snow and ice cover conditions were compiled for an area in and around the Upper Susitna River Basin of Alaska. The 10 years of tabulated data (from September 1964 to May 1974) for 16 locations include average monthly values of air temperature, precipitation amounts (including total snowfall), and maximum depth of snow on the ground. Ice thickness measurements and other related winter surface conditions on rivers in the basin are included in the report. Detailed observations on physical properties of the snow cover and the rate at which soil thaws in the spring are also provided for selected stations near the area under study. (Author).

Rahilly and published by . This book was released on 2014 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaska is a natural laboratory for the study of how active volcanism interacts with underlying seasonal snow, perennial snow, and glacial ice cover. While over half of the historically active volcanoes in Alaska have some degree of perennial snow or glacial ice, all Alaskan volcanoes have a covering of seasonal snow for a period of time throughout the year. Previous research has centered on how volcanic deposits erode away the underlying snow/ice cover during an eruption, producing volcanic mudflows called lahars. Less emphasis has been placed on how variations in the snow/ice cover substrate effect the efficiency of meltwater generation during a volcanic eruption. Glacial ice, perennial snow, and seasonal snow can all contribute significantly to meltwater, and therefore the variations in the types of snow/ice cover present at Alaskan volcanoes must be analyzed. By examining the changing spatial extent of seasonal snow present at a volcano during multiple Alaskan summers, the approximate boundaries of perennial snow and ice can be mapped as the snow/ice cover consistently present at the end of each ablation season. In this study, two methods of snow/ice cover mapping for Redoubt and Pavlof volcanoes are analyzed for efficiency and accuracy. Identification of the best method allows for mapping of the snow/ice cover consistently present during each Alaskan summer month over at least two different years. These maps can serve as approximations for the snow/ice cover likely to be present at both volcanoes during each summer month. Volcanic deposits produced during the 2009 Redoubt and 2013 Pavlof eruptions are spatially linked to these snow/ice cover maps so that future research can focus on the interaction between deposits and type of snow/ice substrate. Additional observations and conclusions are made regarding how the visible snow/ice cover varies during and after each eruption.

Download or read book The Seasonal Snow Cover of Arctic Alaska written by Carl S. Benson and published by Washington, D.C. : Arctic Institute of North America. This book was released on 1969 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The snow cover of Arctic Alaska includes two distinct types which are separated by the Brooks Range. On the Arctic Slope the snow has a wind-swept, continuous surface which resembles that of the Greenland or Antarctic Ice Sheets. The snow of Interior Alaska, between the Brooks and Alaska Ranges, lies in heavily forested land with patches of smooth continuous snow cover occurring on lakes and swamps and on hilltops above timberline. It is possible to differentiate between Arctic and Pacific source areas for snow deposited on the Arctic Slope. The heavy isotopes of hydrogen and oxygen are more abundant in precipitation from the Pacific. The electrical conductance of melt waters derived from Pacific snowfall is also higher than that from Arctic storms. More investigations are needed, but present information suggests that Arctic sources make up nearly half of the precipitation on the Arctic Slope. This is an important factor in considerations on the origin and maintenance of the Pleistocene North American Ice Sheet. (Author).
