where is the gulkana glacier located Leave a comment

The typical minimum winter under-ice discharge is about 0.04 m3/s, which is about three to four times the average contribution from the combined geothermal melt of the bed of the glacier and melting caused by the loss of potential energy from ice motion. These data constitute the longest continuous set of mass-balance data in North America (Josberger and others, 2007) which are used to understand glacier dynamics and hydrology, and understand the glacier's response to climate change. This is one of the essential reference glaciers, with observations and mass balance measurements taken every year for more than 50 years. Gulkana Glacier is located in the Alaska Range (continental climate) and Wolverine Glacier is located in the Kenai Mountains (maritime climate). Overview College Glacier is a relatively short, receding, and thinning glacier in the Eastern Alaska Range near the Richardson Highway. View from southwest of the glacier (August, 2013). Daily average temperatures range from a low of -35°C to a high of 16°C. In the future, runoff volumes from Interior Alaska glaciers, such as the Gulkana, are likely to be altered much more strongly by climate change compared to glaciers located in coastal, maritime environments. Orange symbols represent far-field weather stations used to fill … Gulkana Glacier is a glacier that flows from the ice fields of the south flank of the eastern Alaska Range. Direct field measurements are combined with weather data and imagery analyses to calculate the seasonal and annual mass balance of each glacier. 37°44′48″N 119°16′58″W. The glacier, looming 1300 meters in elevation, is located along the south flank of the eastern Alaska Range. Subscribe to our blog's rss feed, or find us on Github.
