Long-term mass loss from the accumulation zone of the Llewellyn Glacier, SE Alaska

Satellite-derived velocity data products and mass loss estimates can be problematic when applied to slow-moving systems with smaller magnitude changes such as the accumulation zone of the Llewellyn Glacier of the Juneau Icefield. As a result, inter-annual variability may be systematically over or un...

Description
Summary:Satellite-derived velocity data products and mass loss estimates can be problematic when applied to slow-moving systems with smaller magnitude changes such as the accumulation zone of the Llewellyn Glacier of the Juneau Icefield. As a result, inter-annual variability may be systematically over or under predicted. Ground survey data has the potential to provide a long term, higher resolution record of slow but significant changes in the accumulation zones of glaciers. Here we compare satellitebased velocity data with GPS data collected in a 2010 ground survey across the Llewellyn Glacier.
