A Remote sensing approach for monitoring debris-covered glaciers in the high altitude Karakoram Himalayas
Debris-covered glaciers, unlike other types of glaciers, are difficult to map using visible and infrared imagery. Moreover, high altitude glaciers are difficult to map using fieldwork data due to the inaccessibility. In this study, supraglacial debris cover is mapped using Landsat TM and ETM+ images acquired from 1990 to 2010 and a digital elevation model (DEM) which is derived from Shuttle Rad...
متن کاملEstimating the volume of glaciers in the Himalayan–Karakoram region using different methods
Ice volume estimates are crucial for assessing water reserves stored in glaciers. Due to its large glacier coverage, such estimates are of particular interest for the Himalayan–Karakoram (HK) region. In this study, different existing methodologies are used to estimate the ice reserves: three area–volume relations, one slope-dependent volume estimation method, and two ice-thickness distribution ...
متن کاملObservations on rock glaciers in the Himalayas and Karakoram Mountains of northern Pakistan and India
Rock glaciers are abundant in the Lahul and Garhwal Himalayas of northern India and the Karakoram Mountains of northern Pakistan. They exhibit morainic and protalus forms and are restricted altitudinally and climatically to sites above approximately 4000 m asl. and regions where annual precipitation is less than 1000 mm. In these areas, morainic rock glaciers are large, usually )1 km long, )100...
متن کاملSlight mass gain of Karakoram glaciers in the early twenty-first century
Assessments of the state of health of Hindu-Kush–Karakoram– Himalaya glaciers and their contribution to regional hydrology and global sea-level rise suffer from a severe lack of observations1. The globally averaged mass balance of glaciers and ice caps is negative1–3. An anomalous gain of mass has been suggested for the Karakoram glaciers2,4–6, but was not confirmed by recent estimates of mass ...
