Abstract:

LONG-TERM GOALS. Our long-term goals are 1 to determine how changes in particle size distribution, composition and concentration on the shelf affect inherent optical properties attenuation, absorption and scattering and 2 correlate these measurements with hydrographic measurements including wave and current shear stress as measured by others to determine the forcing functions and biological processes that cause the temporal and spatial variations in optical properties on the shelf. OBJECTIVES. 1. Determine the relationship between inherent optical and particle characteristics composition, mass concentration, and size distribution for the area studied during the Coastal Mixing and Optics CMO Advanced Research Initiative ARI. 2. Determine how the above relationships vary between periods of high stratification late summer and low stratification early spring conditions. 3. Determine the significance of the presence of large aggregates on the inherent optical properties.
