5/8/2023 0 Comments Glims glacial map![]() The observed area and the elevation changes indicate that the Echaurren Norte Glacier may disappear in the coming years if negative mass balance rates prevail. a −1 during an unprecedented drought in Central Andes of Chile. Highly negative mass change rates were found from 2010 onwards, with −1.20 ± 0.09 m w.e. It ensures that inventories carried out in different places by different people are comparable. The Global Land Ice Measurements from Space (GLIMS) programme defines guidelines and rules for conducting glacier inventories 3-10. These estimates agree with the results obtained with the glaciological method during the same time span. Glacier inventories are a specific technique for mapping glacier extent, volume and characteristics. a −1 was detected for the period 2000–2009. Within this overall downwasting trend, a positive mass balance of 0.54 ± 0.40 m w.e. The results indicated a mean cumulative glacier wide mass loss of −40.64 ± 5.19 m w.e. Map of Washington showing areas with alpine glaciers. The geodetic mass balances were calculated by differencing digital elevation models derived from several sources. Click inside the rectangular inset areas in the map to open more detailed maps of the alpine glaciers. Over this period, this glacier lost 65% of its original area and disaggregated into two ice bodies in the late 1990s. In this study, we calculated glacier area changes using satellite images and historical aerial photographs, as well as geodetic mass balances for different periods between 19 for the Echaurren Norte Glacier in the Central Andes of Chile. About three-quarters of the Earth’s fresh water is held in ice sheets and mountain glaciers, so recognizing glacial changes is crucial to monitoring water supplies. A number of different layers in this interface can be viewed and spatially queried including: GLIMS Glacier Outlines, other glacier databases such as the World Glacier Inventory, Regional Coordinator Locations, and others. ![]() The data has been obtained by the direct glaciological method since 1975. The GLIMS Glacier Viewer is an interactive map which gives a view of data in the GLIMS Glacier Database. The Echaurren Norte Glacier is a reference glacier for the World Glacier Monitoring Service (WGMS) network and has the longest time series of glacier mass balance data in the Southern Hemisphere.
