Wind wave and water level dataset for Hornsund, Svalbard (2013-2021)

Abstract

Underwater pressure sensors were deployed near-continuously at various locations of the nearshore (8-23m depth) Hornsund fjord, Svalbard, between July 2013 and February 2021. Raw pressure measurements at 1Hz were used to derive mean water levels, wave spectra and bulk wave parameters for 1024s bursts at hourly intervals. The procedure included subtracting atmospheric pressure, depth calculation, fast Fourier transform, correction for the decrease of the wave orbital motion with depth and adding a high-frequency tail. The dataset adds to the sparse in situ measurements of wind waves and water levels in the Arctic, and it can be used, for example, for analysing seasonal wind wave conditions and inter-annual trends and calibrating/validating wave models. The dataset is stored in the PANGAEA repository (10.1594/PANGAEA.954020; Swirad et al., 2023).
