  • Confidence in the 90th percentile Kinetic energy due to waves at the seabed in the Celtic Sea, Channel and Bay of Biscay. Values are on a range from 1 (Low confidence) to 3 (High confidence). The confidence assessment considered factors such as: • Quality of training data and methods used to construct the model. • Temporal resolution. • Spatial resolution Detailed information on the confidence assessment in Populus J. et al 2017.

  • 90th percentile Kinetic energy due to waves at the seabed in the Celtic Sea, Channel and Bay of Biscay - Created using the Homere French hindcast archive.HOMERE is a sea-states hindcast database, based on WAVEWATCH III model (version 4.11) on a unstructured grid covering the English Channel and Bay of Biscay (NGUG) over 1994-2016 period (23 years). For the purpose of EMODnet Seabed Habitat broadscale habitat map product, values were integrated over period 2010-2015. Values are averages of annual percentiles 90th. The spatial resolution of the dataset is 0.001 decimal degrees (100m), but the spatial resolution of the original datasets varies, from 300m is coastal waters to several kilometers in offshore areas. The kinetic energy were calculated using the formula 0.5*m*ubr*ubr*, where m is the water density constant value (taken as 1027 kg.m-3) and ubr is the WAVEWATCH III model variable (rms of bottom velocity amplitudes) Created by the EMODnet Seabed Habitats project consortium using the HOMERE hindcast archive (Accensi Mickael, Maisondieu Christophe (2015).
