Changes of glacier facies on Hornsund glaciers (Svalbard) during the decade 2007–2017

Abstract: Firn area of studied glaciers between 2012 and 2017 decreased from 24% to 41%  Max. loss of 14% of firn contribution to glacier area was recorded on Hansbreen  Hornsund's local climatic conditions shape east-to-west gradient of firn area loss  The Internal Reflection Power is recommended for glacier zones distinction by GPR  Results of analysis of modern SAR data are promising for distinguishing firn and SI Highlights (for review)

“…It includes all 79 available snow profiles collected on Hansbreen in 1989-2021. These were performed: to calibrate mass balance measurements and modelling; 19,[25][26][27][28][29][30][31] to estimate the snow cover depth using indirect methods, such as ground-penetrating radar (GPR) [32][33][34] and remote sensing [35][36][37] ; to determine the evolution of the seasonal snow cover 17,18,[38][39][40] ; and to calculate concentration and fluxes of pollutants deposited in the snowpack 23,[41][42][43][44] .…”

“…and outflows of cold and fresh water from the fjords (Figure 1; Bensi et al 2019). Along the western Spitsbergen coast, there are four major fjords, Hornsund, Bellsund, Isfjorden, and Kongsfjorden (Figure 1), that are characterized by the presence of tidewater glaciers in the inner part (e.g., Strzelecki et al 2018;Halbach et al 2019;Barzycka et al 2020;Szeligowska et al 2021). Also, Storfjorden, which is occupied by glacier systems, strongly impacts the oceanography of Svalbard (Skogseth et al 2008).…”

“…Some successful studies on glacier zone detection and monitoring in polar regions have been carried out, using analysis of sigma0 and comparison to terrestrial data (e.g., [21][22][23][24][25]). These studies are limited to only a few glaciers and to a single-or dual-pol SAR mode of C-band SAR data.…”

“…These studies are limited to only a few glaciers and to a single-or dual-pol SAR mode of C-band SAR data. Barzycka et al [25], in a study of changes in glacier zones on Hornsund glaciers (Spitsbergen, Svalbard), recognized limitations in the K-means unsupervised classification of sigma0 of both single-and dual-polarization SAR images in distinguishing glacier zones. The limitations are related to the thickness of glacier facies, heterogeneity of the ice body, and the local character of a structure.…”
