Abstract
Two ADCP deployments were undertaken in 2016 and 2020* to characterise the tidal currents at AMETS B. Both depoyments were carried out using Teledyne RDI Workhorse Sentinels (300 & 600 kHz) in self-contained mode with data only available after recovery. The instrument has a number of built-in quality control tests and also provides ancillary data such as Echo Intensity and Error Velocity which can be used by the end-user to further refine data quality. The most uncertain part of the data profile was that near the surface due to strong echo from the “hard” sea surface. In practice, this meant that the velocity data for the top 5-6 % of the water column were discarded during analysis.
Tidal current characterization at the Atlantic Marine Energy Test Site AMETS B is located in United Kingdom.
