There was a slight but not significant decrease in precipitation. RM 2J91BX7 Aerial view of Churchill barrier No.2 which links Lamb Holm and Glimps Holm, Orkney islands, Scotland.

GLIMS AERIAL PHOTOS SERIES

Annual air temperature showed a significant upward trend in the last 30 years, with larger temperature increases at lower elevations. RM D6FMT8 The Churchill Barriers are a series of four causeways in the Orkney Islands, Scotland, with a total length of 1.5 miles (2.3 km) RF KJ734M Churchill Barriers, Orkney, Scotland, United Kingdom. The outlines of the identified glaciers were transferred to work maps and later digitized and compiled onto a 1:500,000 scale final map. Canada’s Department of Energy, Mining and Resources used 1:30,000 to 1:60,000 scale aerial photos to identify perennial snow and ice. This is necessary because for the inventory to be included in WGI/WGMS/GLIMS. The first Canadian glacier inventory was carried out between 19. Results include (1) an estimated glacierized area of 569.6 ± 21 km2 in 2003, (2) an overall loss in glacierized area of 22.4% from 1970 to 2003, (3) an average rise in glacier terminus elevations by 113 m and an average rise in the median elevation of glaciers by 66 m, showing a shift of ice to higher elevations, especially on the eastern side of the Cordillera, and (4) an increase in the number of glaciers, which indicates disintegration of ice bodies. Within the framework of the program Global Land Ice Measurements from Space (GLIMS) a glacier inventory of the Peninsula Muñoz Gamero in the southernmost Andes of Chile (53°S) has been generated using aerial photopgrahy and Landsat Thematic Mapper imagery. The aerial photographs were used because they have a better resolution. We examined changes in glacier area on the eastern and western side of the Cordillera in relation to topographic and climate variables (temperature and precipitation).

We derived new glacier outlines from the 2003 SPOT images, and ingested them in the Global Land and Ice Measurements from Space (GLIMS) glacier database.

A sample image of Alaskan glaciers from the GLIMS glacier viewer application. Abstract We present spatial patterns of glacier fluctuations from the Cordillera Blanca, Peru, (glacier area, terminus elevations, median elevations and hypsography) at decadal timescales derived from 1970 aerial photography, 2003 SPOT5 satellite data, Geographic Information Systems (GIS) and statistical analyses. These additional sources include other satellite observations, such as observations from Satellite Pour l’Observation de la Terre (SPOT) and EMI+, as well as maps, aerial photographs, and historical observations dating back to 1850.
