Spatial Coherence of Nonlinear, Nonstationary, Non-Gaussian Ocean Waves on a One-Mile Scale from Scanning Altimeter Radar

Abstract

The lack of good ocean surface data on the one-mile or more scale is a major stumbling block for proper evaluation of proposed Mobile Offshore Base (MOB) conceptual designs (Fig. 1). A general model and associated software for stationary, linear, statistical, directional wave systems has been available for some time. If that model can appropriately be used for design of marine mega-structures, then there is no problem in proceeding with conceptual MOB designs and their evaluations. However, it is believed that storm waves might be locally stationary, but on a larger area scale might be nonstationary with patches of clusters of high waves, giving local variances inconsistent with stationary, linear, statistical, directional wave systems. There is a strong need for more knowledge concerning nonlinearity and coherence of storm waves on the mega-structure scale.
