Variability of Irradiance in the Wave Boundary Layer
Abstract
Our primary goal is improve our understanding of the role of surface waves, bubble clouds, and near surface oceanic processes on the spatial distribution of oceanic irradiance. The objectives are to: 1. Measure the variance in the oceanic light field. 2. Associate the variance in the light field with surface waves and variance in the inherent optical properties and physical properties. We are using an autonomous underwater vehicle (AUV) to make spatial measurements of physical (near surface T, C, turbulence levels), and optical (a, c, bb, Ed) fields from sensors mounted on OSU's AUV. We are working with Satlantic to also incorporate a radiance camera within the AUV. By measuring the irradiance field at high frequency we will be able to provide the optical measurements needed to evaluate models of surface effects on the irradiance field (e.g., Zaneveld et al. 2001). The optical measurements will be combined with physical measurements to improve physical models associated with surface mixing.
