Doglioni, Francesca; Ivanov, Vladimir; Kanzow, Torsten; Rabe, Benjamin; Ricker, Robert (2021): Steric height and bottom pressure water equivalent derived from mooring data at the Laptev Sea continental slope [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.931875

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 Laptev Sea continental slope. Data were collected between September 2013 and August 2015 in the framework of the project Nansen and Amundsen Basins Observations System II (NABOS-II moorings M1_4 and M1_6, Polyakov et al., 2019). Temperature and salinity were linearly interpolated between the shallowest sensor (26 m) and the deepest sensor (700 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.
