Changes in Surface Characteristics of Glaciers in Jotunheimen
Hovedinnhold
Project description
Background:
Glaciers such as Storbreen, Hellstugubreen, and Gråsubreen in the Jotunheimen region exhibit dynamic surface features, including crevasse patterns and supraglacial drainage channels. High-resolution orthophotos from 1997, 2009, and 2019, along with laser scanning data from 2009 and 2019, offer an opportunity to study temporal changes in these features.
Research Questions:
- What are the temporal changes in crevasse patterns and supraglacial drainage systems on these glaciers?
- How can these changes be quantified using available remote sensing data?What do these changes indicate about the glaciers’ response to climatic and environmental factors?
Work Plan:
- Compile and process orthophotos and laser scanning datasets for the specified years.
- Develop and apply methodologies to quantify changes in surface features over time.
- Compare and contrast changes across the three glaciers to identify common patterns or unique behaviours.
