The Karakoram Anomaly has been intensively investigated, but the factors that control this anomaly, such as glacier velocity, topography, and mass balance, remain poorly understood. To improve our understanding of balance Glacier, in study, spatiotemporal variability four velocities Hunza Basin range were surveyed using co-registration optically sensed images correlation (COSI-Corr) on Landsat ...

Moraine sequences of mountain glaciers can be used to infer spatial and temporal patterns of climate change across the globe. Alaska is an accessible high-latitude location in the Northern Hemisphere and contains a rich record of alpine glaciation. Here, we highlight the key chronologies from three mountain ranges in Alaska that reveal the timing and spatial extent of Late Pleistocene glaciatio...
Glaciers in China are primarily located in the Tibetan Plateau (TP) and surrounding high mountains. The Chinese Glacier Inventory indicates that there are 46 377 glaciers in western China. Meteorological records indicate that air temperature in western China has risen by 0.28C per decade since 1951, and 1998 was the warmest year; precipitation in the region increased by 5–10% per decade from 19...
Abstract. The length of a glacier is key determinant its geometry and an important parameter in inventories modeling; centerlines are the lines along which main flow glaciers takes place and, thus, crucial inputs for many glaciological applications. In this study, maximum lengths global were extracted using self-designed automatic extraction algorithm based on latest inventory data, digital ele...
The sensitivity of high-elevation lakes to acidic deposition was evaluated in five national parks of the Rocky Mountains based on statistical relations between lake acid-neutralizing capacity concentrations and basin characteristics. Acid-neutralizing capacity (ANC) of 151 lakes sampled during synoptic surveys and basin-characteristic information derived from geographic information system (GIS)...
