In this work we present a unique set of coincident and collocated high- resolution observations of surface currents and directional properties of surface waves collected from an airborne instrument, the Modular Aerial Sensing System (MASS), collected off the coast of Southern California. High-resolution observations of near surface current profiles and shear are obtained using a new instrument, DoppVis, capable of capturing horizontal spatial current variability down to 128m resolution. This data set provides a unique opportunity to examine how currents at scales ranging from 1-100 km modulate bulk (e.g. significant wave height), directional and spectral properties of surface gravity waves. Such observations are a step toward developing better understanding of the underlying physics of submesoscale processes (e.g. frontogenesis and frontal arrest) and the nature of transitions between mesoscale and submesoscale dynamics.
