Sea ice and wave breaking patterns during the Terra Nova Bay Polynya event on September 19, 2019, based on very high resolution satellite imagery

Results of the WorldView-2 (WV2) panchromatic image analysis, described in Herman and Bradtke 2023 "Fetch-limited, strongly forced wind waves in waters with frazil and grease ice — spectral modelling and satellite observations in an Antarctic coastal polynya". The image, which cover part of the polynya in Terra Nova Bay, was taken on September 19, 2019 at 21:22 UTC. The spatial resolution of source data is 0.5 m. The zip file contains: “AOI” folder with the analyzed area outline in SHAPEFILE format “whitecaps” folder with breaking wave signatures (polygons) in SHAPEFILE format Sea ice (1) - water (2) mask in GeoTIFF format (0 means NoData) Data are provided in WGS 1984 / UTM Zone 58S projection (EPSG:32758) This work has been financed by Polish National Science Centre projects no. 2018/31/B/ST10/00195 (“Observations and modeling of sea ice interactions with the atmospheric and oceanic boundary layers”) and 2022/47/B/ST10/01129 (“Sea ice, waves and turbulence – from laboratory scale to improved large-scale modelling”), and by the University of Gdansk, Laboratory of Physical Oceanography, DS 531-OA02-D425-23.
