Quality-controlled bottom pressure dataset to analyse for continental shelf waves: Contribution to WP1 OI (Deliverable D1.6)

In this deliverable, we present the first version of a compilation of historical moored timeseries of pressure within 50 m of the seabed that have been deployed over the past 50 years over Antarctic continental shelves and slopes. We further compare the type of records contained within our compilation with state-of-the-art pressure time series typically observed by higher-sensitivity sensors directly seated on the seabed and demonstrate how this new dataset can be used to evaluate related satellite products in polar settings. The standardized data collection of near-seabed pressure records we present is restricted to the region south of 60°S (Figure 1) and is freely accessible from SEANOE (https://www.seanoe.org/data/00983/109453/ ), and we hope to complement it with additional records and maintain it in the future. We refer to this data compilation as the OCEAN ICE near-seabed pressure compilation herein. Though beyond the scope of this data release report, this dataset provides an opportunity for a systematic study on pan-Antarctic ocean wave dynamics.
