This dataset has been created as a comparative dataset for assessment of satellite-derived sea level anomaly in the publication Doglioni et al. (2022). The dataset includes two time series, one of steric height and another of bottom pressure equivalent height, respectively computed from moored temperature and salinity data and ocean bottom pressure records at the Arctic Cape shelf break. Data were collected between October 2015 and July 2018 in the framework of the project Changing Arctic Transpolar System (CATS mooring AK3). Temperature and salinity were linearly interpolated between the shallowest sensor (50 m) and the deepest sensor (1448 m) onto a regular pressure grid with vertical spacing of 2 m. Constant extrapolation was performed above the shallowest sensor and no extrapolation was performed below the deepest sensor. Temperature and salinity vertical profiles were converted into density profiles using the Matlab sw_dens routine (Fofonoff & Millard, 1983). Bottom pressure records are detided using the Matlab routine t_tide (Pawlowicz et al., 2002) and instrumental drifts were removed. Steric height and bottom pressure equivalent height time series were averaged into monthly time steps.
