Ice type maps for Hornsund, Svalbard, 10.2002-8.2025

The dataset contains 4123 maps of ice type distribution in Hornsund fjord at 50 m resolution for the period of 2002-10-30 to 2025-08-31. The maps are based on binary maps available in the PANGAEA repository: https://doi.org/10.1594/PANGAEA.986427 (Papin et al., 2025a; Envisat ASAR 2002-2012), https://doi.org/10.1594/PANGAEA.969031 (Swirad et al., 2024; RADARSAT-2 2012-2016), https://doi.org/10.1594/PANGAEA.963167 (Swirad et al., 2023; Sentinel-1A/B 2014-2023), https://doi.org/10.1594/PANGAEA.987853 (Papin et al., 2025b; Sentinel-1A 2023-2025). When two images occurred on the same day, RADARSAT-2 was prioritised over Envisat ASAR and Sentinel-1 because of its lower noise floor. The pixel values of the ice type maps indicate: 0 = open water, 1 = drift ice, 2 = landfast ice, 3 = glacier ice, 7 = uncertain, 8 = masked, 9 = landmask. Note that from 2023-07-01 spatial extent and cell alignment changed.

Project
  • Project title: HIRLOMAP: High resolution and local sea ice product generation for arctic operations Project ID: 4000146036/24/I-DT-bgh Project description: To address the Arctic operations priority area within the ESA’s SUP Initiative we established the project HIRLOMAP. Our focus is towards (a) tactical product delivery (sea ice maps, short-term forecasts of ice conditions, simulations of ice dynamics) for detailed local analysis in the vicinity of a vessel or offshore structure to support immediate operations or operation planning, (b) extending detection capabilities to smaller icebergs and more detailed ice type / open water separation for route planning, (c) providing local charts of fast and fjord ice conditions to local communities for evaluations of the safety of on-ice travels, and (d) monitoring of coastal sea ice for research on coastal erosion and flooding. The required product coverage is tens of kilometers with the highest possible spatial resolution between 5 and 50 meters. For the project we use data from SAR, optical and thermal satellite sensors.
