Since 1990, Yahtse Glacier in southern Alaska has advanced at an average rate of ∼100m year−1 despite a negativemass balance, widespread thinning in its accumulation area, and a low accumulation-area ratio. To better understand the interannual and seasonal changes at Yahtse and the processes driving these changes, we construct velocity and ice surface elevation time series spanning the years 19...

Wedel Jarlsberg Land in Svalbard is a region with varied periglacial landscape. In the mountains and valleys, climate polar permafrost. During summer, near-surface ground layer thaws. The Werenskiold Glacier, together its end moraine, are located central part of this area. rate morphological changes observed within moraine varies time space, depends on environmental conditions. This study inves...

We measured in situ cosmogenic 10Be in 16 bedrock and 14 boulder samples collected along a 40-km transect outside of and normal to the modern ice margin near Sikuijuitsoq Fjord in central-west Greenland (69 N). We use these data to understand better the efficiency of glacial erosion and to infer the timing, pattern, and rate of ice loss after the last glaciation. In general, the ages of paired ...

Comparative study was carried out on the production of protease using isolate from moraine. The isolates were screened on gelatin plates for gelatin hydrolyses by the different isolates. Among the all tested isolate No. 7 EHN produced the highest activity. while under the fermentation conditions after 3 days the maximum yield of protease was 277 U/ml. The protease production from marine isolate...

This paper describes the development and implementation of a Bayes network based system for distinguishing terrestrial rocks from meteorites from onboard the mobile robotic rover Nomad. Equipped with a color camera and spectrometer, Nomad autonomously made the first robotic identification of a meteorite, in January 2000 at the Elephant Moraine, Antarctica. This paper discusses rock classificati...

To investigate causes of tree species distributions across soil resources in northern Michigan, we conducted a seedling transplant experiment with five species showing different site affinities: Acer saccharum Marsh. (sugar maple), Prunus serotina Ehrh. (black cherry), and Fraxinus americana L. (white ash), which are associated with high-fertility mesic moraine; Quercus rubra L. (red oak), asso...
