We applied photogrammetric methods with aerial when glaciers undergo changes in extent and volume. As photography from 11 different years between 1946 and 2005 glaciers and ice caps (GIC; all glaciers outside of the Antarc- to assess changes in area and volume of 33 glaciers in the tic and Greenland ice sheets) lose volume, sea level rises Cariboo Mountains of British Columbia for the latter half of (Radic´ and Hock, 2011). The largest GIC contributions to the 20th century. These are used to identify changes in extent sea level rise include the Canadian Arctic Archipelago and and elevation primarily for the periods 1952–1985, 1985– Gulf of Alaska regions (Gardner et al., 2011; Berthier et al., 2005, and 1952–2005. All glaciers receded during the pe- 2010), but recent work demonstrates that, collectively, small riod 1952–2005; area retreat averaged −0.19 ± 0.05 % a−1. glaciers (< 1 km2/ contribute a significant amount to total From 1952 to 1985, nine glaciers advanced; following GIC volume (Bahr and Radic,´ 2012).
