ABSTRACT
The article presents a study on icefield-wide volume change rate and glacier speed estimates for the Cordillera Darwin Icefield (CDI) in Southern Chile. It says that velocities are measured from radar and optical imagery and the study used digital elevation models (DEMs) and weighted linear regression. Results showed that the CDI lost mass at an average rate of 3.9±0.3 Gtyr(-1) and the equivalent to a sea level rise (SLR) of 0.01±0.001 millimeter Gtyr(-1).
