ALPINE-TYPE MOUNTAINS

geomorphological and sedimentological evidence of alpine glaciers in the zagros mountains, dinevar, iran

the altitude to which the past glaciers had been extended during the last glacial period in dinevar basin, western iran, can be estimated based on glacier-geomorpic evidence such as cirques, u-shaped valleys, and the moraines in lowlands. this study estimates the elevation of snowline during this period for the basin as the objective of the research. topographic and geologic maps, landsat image...

Aortic Dissection Type A in Alpine Skiers

PATIENTS AND METHODS 140 patients with aortic dissection type A were admitted for cardiac surgery. Seventy-seven patients experienced their dissection in the winter season (from November to April). We analyzed cases of ascending aortic dissection associated with alpine skiing. RESULTS In 17 patients we found skiing-related aortic dissections. Skiers were taller (180 (172-200) cm versus 175 (1...

Melting Alpine Glaciers in the Rocky Mountains: Impacts on Ecosystems, Agriculture, and Economics

Seasonal changes in an alpine soil bacterial community in the colorado rocky mountains.

The period when the snowpack melts in late spring is a dynamic time for alpine ecosystems. The large winter microbial community begins to turn over rapidly, releasing nutrients to plants. Past studies have shown that the soil microbial community in alpine dry meadows of the Colorado Rocky Mountains changes in biomass, function, broad-level structure, and fungal diversity between winter and earl...

Alpine Glacier Change in the Eastern Altun Mountains of Northwest China during 1972-2010

Accurately mapping and monitoring glacier changes over decades is important for providing information to support sustainable use of water resource in arid regions of northwest China. Since 1970, glaciers in the Eastern Altun Mountains showed remarkable recession. Further study is indispensable to indicate the extent and amplitude of glacial change at basin and individual glacier scale. In this ...
