Ice distribution in Hornsund fjord, Svalbard from Sentinel-1A/B (2014-2023)

This dataset contains binary maps of ice (1) and open water (0) in Hornsund fjord, Svalbard at 50 m resolution. The maps are based on the Sentinel-1A/B Synthetic Aperture Radar (SAR) archive between 14.10.2014 and 29.06.2023 with an average image frequency of 1.57 days. An algorithm was run on the radar backscatter and incidence angle images to divide fjord into typically 5 discontinuous segments, which were then classified as either ice or open water. A document containing details on the scenes and polarisation channels used, the number of segments and the level of manual editing is provided.

  • Project title: Wave energy delivery to the shores of Hornsund fjord, Svalbard  Project ID: UMO-2021/40/C/ST10/00146  Project description: This study focuses on modelling wave energy delivery to the shores of Hornsund, a ~300 km2 fjord of SW Spitsbergen, Svalbard, through 1) a fjord-scale modelling of wind wave transformation that incorporates the role of sea ice in wave attenuation, and 2) a beach-scale empirical modelling of water level maxima. The overall goal is to understand how changing climate, namely sea ice decline and increasing storminess, impacts Arctic shores, and to predict shoreline water levels at present and in future.  Project homepage:  Project financing institution: National Science Centre, Poland
