Abstract Bed shear stress (in N.m-2) is a measure of the friction of water on the seabed due to the M2 tide. Used as layer for habitat.

Lineage Bed shear stress was estimated using a 2D hydrodynamic model of the north-west European shelf. This model, developed at the POL, is used to predict the mean M2 tidal curennt on the bottom at a spatial resolution of 1/8° longitude by 1/12° latitude (about 8 km cell size). Bed stress was calculated using a quadratic expression where stress depends on the predicted maximum ellipse current and on an appropriate bed friction coefficient (here, value 0.0025). Bed shear stress was provided as a regular
