This dataset contains physical oceanographic data, comprising acoustic doppler current profiler (ADCP) and waverider measurements. The ADCP data were collected using a Teledyne RDI Workhorse Sentinel-600 ADCP mounted on a seabed frame at the European Marine Energy Centre (EMEC) full scale tidal test site at Fall of Warness, Orkney - UK. No structures were present around the instrument at the time of the deployment. Data were collected over a two week period between February and March 2005, with a sampling resolution of 20 minutes. Data were processed by the originator using the company’s in-house Integrated Metocean Processing, Analysis and Quality Control Tool (IMPAQCT) software. Data comprise current speed profile (with on average 40-50 bins), current direction profile (vertical bins), echo amplitude (four beams), percentage good pressure and beam solution, pitch, roll, heading, and water temperature. The waverider data were collected using a Datawell Waverider buoy moored at the southern part of the full-scale wave test site at Billia Croo, Orkney. Data were collected over a one year period in 2017, with a sampling resolution of 30 minutes. Data were processed using the Datawell W@ves21 software. Data comprise wave spectral parameters, including significant wave height, spectra peak period, wave direction at the peak frequency, directional spread at the peak frequency, zero-upcrossing period (from spectra), and mean period (T01). Data were collected by the EMEC as part of research focusing on wave and tidal power development.
