North Sea

This region is a significant one for research into mapping and modeling. The amount of data available is huge, but there are significant conflicts between the many mapping syntheses that have been released over time. This compilation is a consensus built primarily from public point data, but also employing published grid/polygon maps.

The comprehensive gridded and pointwise data are available on request. The work was prompted by an investigation of spatial variabilities for seabed mesoscale roughness and drag relevant to tidal modelling (see bibliography).
