Data were collected with a Silixa iDAS, using 10 m gauge length, 2 m spatial resolution, and 1000 Hz sample rate.\n\nProvided here are the DAS-recorded time series for the rapid refreeze event described in Baker & Abbott (2022) (see link below). This covers a date range of 2021-11-10 15:00 UTC to 2021-11-11 17:00 UTC. Data have been decimated to 100 Hz and 20 m (i.e., every 10th channel for 1831 channels, total), as used in Baker & Abbott (2022). Data have been extracted from raw format into 1-hour long .sac* files and organized into directories by channel number, spanning channels 100 to 18400. Time series units are nano-strainrate (nm/m/s).\n\nFor distribution, data have been compressed into .zip files containing all time series files for 100 channels.\n\n\n*For information on the Seismic Analysis Code (SAC) file format:\nhttps://seiscode.iris.washington.edu/projects/sac\n", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2022GL099880", "description": "We present results from a multi-seasonal acquisition of DAS data on a seafloor cable in the Beaufort Sea, Alaska.", "format": "HTML", "mediaType": "text/html", "title": "Rapid Refreezing of a Marginal Ice Zone Across a Seafloor Distributed Acoustic Sensor"}, {"@type": "dcat:Distribution", "accessURL": "https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105243", "description": "We demonstrate a novel method for persistent observation of wave-ice interactions using distributed acoustic sensing (DAS) along existing seafloor fiber optic telecommunications cables.
