Replication Data for: On the variation of ocean surface gravity wave characteristics with wind speed and direction: A case study from offshore Svalbard, Norway

A dataset containing re-sampled data used to optain the results presented in the paper 'On the variation of ocean surface gravity wave characteristics with wind speed and direction: A case study from offshore Svalbard, Norway' publised in 2025. It contains processed strain data in strain unit, converted from the time-differentiated phase measured by an OptoDAS interrogator through a dark fiber in a submarine telecommunication cable. This fiber is trenched into soft sediments at 0-2 m below the seafloor from Longyearbyen to Ny-Ålesund in Svalbard, Norway. The raw data used in the analysis acquired from 2022-08-05 to 2023-09-17, and converted to strain data. To reduce file sizes, we resampled the raw data with a sample rate of 25 Hz, and are archived accordingly. As we have analysed a full year of data only a subset is archieved, but it is enough to recreate the major findings in the paper. The processed data are stored as structured arrays in MATLAB file format and as a matrix in csv files. This data set has no exact positioning data of the fiber optic cable, because they are proprietary to SIKT. However, an approximate cable position can be extracted from https://www.norgeskart.no/ and changing the base layer to 'Nautical charts overview'. Moreover, the distance of each recording channel along the cable from the shore (the fiber enters the fjord at roughly 4.2 km) is given in this data set.
