These are the data used in the analysis and creation of figures in S. Wahlgren, L.C. Biddle, J. Thomson and S. Swart: Direct observations of wave-sea ice interactions in the Antarctic Marginal Ice Zone [Submitted]. Preprint: https://doi.org/10.22541/essoar.168201718.84053333/v1 Abstract: Wave energy propagating into the Antarctic marginal ice zone affects the quality and extent of the sea ice, and wave propagation is therefore an important factor for understanding and predicting changes in sea ice cover. Sea ice is notoriously hard to model and in-situ observations of wave activity in the Antarctic marginal ice zone are scarce, due to the extreme conditions of the region. Here, we provide new in-situ data from two drifting Surface Wave Instrument Float with Tracking (SWIFT) buoys deployed in the Weddell Sea in the austral winter and spring in 2019. The buoy location ranges from open water to more than 200 km into the sea ice. We estimate the attenuation of swell with wave periods 8-18 s, and find an ... : This work was supported by the following grants: Wallenberg Academy Fellowship (WAF 2015.0186), Swedish Research Council (VR 2019-04400 and VR 2020-04281). ...
