Abstract
A number of ADCP deployments were undertaken from 2016 to 2020 to characterise the tidal currents at AMETS A. All depoyments were carried out using Teledyne RDI Workhorse Sentinels (300 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 A is located in United Kingdom.
