The Chilean glacierized area is 23 708 +/- 1185 km(2), including similar to 3200 km(2) of both debris-covered glaciers and rock glaciers. Glacier distribution varies as a result of climatic gradients with latitude and elevation, with 0.8% occurring in the Desert Andes (17 degrees 30'-32 degrees S); 3.6% in the Central Andes (32-36 degrees S), 6.2% in the Lakes District and Palena Province (36-46 degrees S), and 89.3% in Patagonia and Tierra del Fuego (46-56 degrees S). Glacier outlines, across all glacierized regions and size classes, updated to 2015 using Landsat 8 images for 98 complexes indicate a decline in areal extent affecting mostly clean-ice glaciers (-92.3 +/- 4.6 km(2)), whereas debris-covered glaciers and rock glaciers in the Desert and Central Andes appear nearly unchanged in their extent. Glacier attributes estimated from this new inventory provide valuable insights into spatial patterns of glacier shrinkage for assessing future glacier changes in response to climate change.

| This research was supported by Direccion General de Aguas (DGA), Ministry of Public Works, Chile, from where this first national glacier inventory is available. S.U. Nussbaumer and J.L. Garcia acknowledge support from the EPFL Leading House for scientific and bilateral cooperation between Switzerland and Chile. The support in data processing of Rodrigo Saez, Claudio Duran, Andres Ceballos, Camilo Munoz, Miguel Barros, Carlos Mendoza, Tamsin Sepulveda and Jorge Huenante, is greatly appreciated. Comments from Bruce H. Raup, National Snow and Ice Data Center (NSIDC), an anonymous reviewer and the scientific editor, Ian Allison, are greatly appreciated. Mr. Felipe Herrera (R.I.P.), a member of DGA staff who tragically died in 2012, worked in the identification of rock glaciers; this paper is dedicated to his memory. |
