Abstract:

In this program we are investigating the temporal changes in bottom spectral reflectance for a variety of bottom types including corals, seagrasses, and both silicate and calcite dominated sediments. Spectral bottom reflectance is expected to change due to changing environmental conditions and forcing mechanisms such as wind and waves, tides, subsurface currents, and insolation. Conducting this investigation requires new instruments and methods. Thus one of my objectives is to develop a new type of moored system for measuring the relevant parameters needed to characterize and quantify bottom spectral reflectance. We call this system BSAP, for Benthic Stationary Autonomous Profiler. There are a variety of BSAP s developed for this research, each designed for a specific application and method of deployment. Related to this objective is to develop shallow-water optical models that can be tested with BSAP and with additional shipboard and diver synoptic measurements. Another objective is to measure and model photon propagation in the top layer of sediment and in seagrass canopies
