A total of 15 OpenMetBuoys (OMBs) were deployed in the marginal ice zone northwest of Svalbard (array of 14 buoys) and on the fast ice off Greenland (one buoy) as part of RV Polarstern expedition PS131 (ATWAICE) in July - August 2022. The OMBs, also referred to as wave buoys, reported GPS position and wave spectra from 20-minute inertial motion averages at hourly intervals via the iridium satellite network. From these, significant wave height and peak wave period can be calculated. Two of the buoys ceased transmission within days of the deployment, while all other buoys recorded data for several weeks/months. The buoys were deployed on ice floes of various dimensions ranging from 15 m to as large as ~2km. The attached .zip archive contains a netcdf file incorporating all buoy data, several python scripts to read and process the data, as well as selected preliminary data quicklooks. The buoys were build and deployed as a collaboration between the Alfred-Wegener-Institute, the University of Tokyo, and the ... : A corresponding Github repository to process the data provided here has been set up at https://github.com/jerabaul29/2022_07_OMB_Svalbard_AWI_UTokyo_deployment.We acknowledge the AWI procurement and logistics for their administrative support in getting these buoys built. We thank the captain, crew, chief scientist and scientific staff of RV Polarstern expedition PS131 for their great field support. ...
