Kinetic energy at the seabed due to waves - Celtic, North Sea (mean of annual 90th percentile)
Under a specific contract for the EUSeaMap project (ABPMer, 2010), energy layers were produced for the North and Celtic seas. Energy layers are built using data from National Oceanographic Centre (NOC) wave (ProWAM at a resolution of 12.5km) and current models (the CS20, CS3 and NEA models at resolutions of 1.8km, 10km and 35km respectively). A high resolution (~300m) bespoke wave model based on the DHI Spectral Wave model was used to augment the coastal areas where the ProWAM model resolution was inadequate. Wave and current data were combined to produce the input energy layer for the EUSeaMap model. Wave data (wave base derived from peak wave periods) were also used to define the boundary between the circalittoral and deep circalittoral biological zones.The kinetic energy due to wave action at the seabed has been expressed here as KE = › ?wUwp2, where Uwpis the peak value of water particle velocity on the seabed during the passage of the wave. The value of Uwphas been predicted using linear wave theory.A series of some 24 bespoke wave models which cover the full extent of the UK coastline, including Northern Europe and Ireland have been constructed using MIKE21-SW to support production of the KE outputs. Wave height exceedance probabilities were calculated based on the average 5-years of ProWAM data for years 2000 to 2005, these wave parameters were used to calibrate the local wave models and provide information in the open coastal sections of the data layer's extent.
