The objective of this project is to obtain unique, collocated observations of the ocean currents and waves to augment ongoing intensive oceanographic research. The project will enable the collection of ocean current observations over the full water column from two acoustic Doppler current profilers (ADCP), an acoustic Doppler velocimeter (ADV) at about mid-water depth, and surface observations from oceanographic HF radar, all from within a in small spatial area, for a few weeks to a month. These observations will provide insight into the dynamics of nearshore flows adjacent to an SBC-LTER kelp forest research site, while also improving the understanding of the sub-grid scale variability in HF radar observations. The observations will also potentially inform the understanding of unresolved turbulent velocity fluctuations, as well as improve estimates of the turbulent heat flux.
