| Summary: | This data set is used to conduct research as presented in a manuscript entitled "Observation of atmospheric and oceanic dynamics using ocean-bottom distributed acoustic sensing" by Taweesintananon et al. in 2022, which is submitted for peer reviews and publications in a journal. It contains processed strain data in nanostrain unit measured by OptoDAS interrogator through a dark fiber in a submarine telecommunication cable, which was trenched into soft sediments at 0--2 m below the seafloor from Longyearbyen to Ny-Ålesund in Svalbard, Norway. The raw data was acquired from 2020-06-23 to 2020-08-04, and converted to strain data in nanostrain unit. To reduce file sizes, we resampled the raw data with 80% antialiasing filter from 1.55 to 20 ms. This processed data then have a Nyquist frequency of 25 Hz, and are archived accordingly. The processed data are stored as structured arrays in MATLAB file format. This data set has no exact positioning data of the fiber optic cable, because they are proprietary to ... |
