General patterns of bioluminescence potential in surface waters indicate there is an increased signal in near shore waters. While present regional and coastal models are able to show this coastal enhancement, the model grids are not scaled to the physical dynamics governing the transition zone from the near shore to the shoreline. In addition, few measurements of bioluminescence have been made in this transition region because of limitations in both platforms and sensors. This is despite the stated need in a recent report (National Research Council 2003). The report highlights bioluminescence as an environmental variable that often influences planning and execution of naval missions, and, in general, the need for more understanding of littoral processes. The objective of this proposal is to better characterize bioluminescence in the transition zone from the near shore to very shallow water (VSW) environments. Measurements of bioluminescence and other parameters will be made in conjunction with other ONR sponsored physical oceanographers and near shore modelers to provide a basis for a global understanding of how bioluminescent organisms respond in these turbulent and high sheer environments. Specifically this project will:
- Focus measurements in the transition zones from the near shore to VSW
environments (including the surf zone) in conjunction with other physical
measurements.
- Relate cross-shore and along-shore measurements to the shoreline types and
shoreline morphologies, including entrances to ports and harbors over a range of
relevant time scales (i.e. tidal).
- Elucidate differential responses between autotrophic and heterotrophic organisms
to turbulent and high sheer environments.
