Response of Particulate Optical Properties to Coastal Mixing Processes
Abstract
Spatial and temporal variability in particulate and dissolved material is a major source of optical variability in the upper ocean. This research program is aimed at developing a better understanding of the relationships between upper ocean optical properties and particulate and dissolved seawater constituents, and to determine how physical processes influence these relationships. We are refining individual particle measurement methods and developing approaches to use individual particle results for interpretation of both inherent and apparent bulk optical properties. The work comprises a combination of instrument development and field studies in coastal waters of the eastern U.S. continental shelf. Results to date emphasize the importance of particles, especially phytoplankton, in determining vertical and temporal optical variability on the continental shelf. Physical processes have been found to contribute to optical variability most often indirectly through their effect on phytoplankton distributions, but major storms can have more direct and immediate effects due to advection and resuspension.
