Wave recorders; current profilers

This dataset contains wave spectra, wave statistics and current data collected by surface and subsurface moorings across three sites in the Bristol Channel between March 2010 and April 2011. A Datawell Mk.III directional Waverider buoy was moored at one site collecting wave spectra and statistics data while Nortek Acoustic Wave and Current meters (AWAC) were moored at the seabed in trawl resistant frames at two sites. The AWACs collected wave data from the surface and current data through the water column split into 2 m bins. TRIAXYS directional wave sensors with onboard Nortek Aquadopp current profilers were also deployed at the two sites. Like the AWAC moorings, the TRIAXYS moorings collected wave data from the surface and current data through the water column split into 1 m bins. The data were collected as part of the environmental impact assessment of the proposed Atlantic Array offshore wind farm. GEMS Survey Ltd were contracted to conduct the data collection and provided the data to The Crown Estate as the landowner of the UK seabed out to 12 nautical miles. The data and associated metadata reports are held at the British Oceanographic Data Centre, as a MEDIN Data Archiving Centre.
