Svalbard is a scientifically important location to study as it is a particularly temperature-sensitive glaciated region and has a range of different glaciological and climatic environments. Previous research indicates that the area is rapidly responding to climate change and increasing air and water temperatures, which could have global ramifications including flooding and restricted access to freshwater resources.
Our research will make a significant contribution to geographical knowledge by improving understanding of Svalbard glaciers and their response to changes in global climate. This research project aims to tie together a range of scientific focuses to better understand the geomorphological processes taking place in high arctic glaciers. Although this research is specific to Longyearbreen glacier, Svalbard, the concepts identified and findings discovered may be applicable to other, less accessible, high artic glaciers.
Research was conducted over a total of 22 days, using a variety of field techniques such as, GPS mapping, water chemistry analysis and hydrology measurements. Despite the decline in Longyearbreen glacier elevation, the rate of thinning under high debris thickness has reduced from previous years. Discharge of the proglacial stream of Longyearbreen glacier increased over the study period whereas melt rates remained relatively consistent, most likely due to the release of previously stored meltwater. Suspended sediment present in the proglacial system increased throughout the study period alongside a gradual increase in discharge and cross-sectional area.
Through understanding the processes of the Longyearbreen glacial system, we can better understand how the system, and other relatable systems, may evolve in the future.
