Spatial and Diel Variability in Photosynthetic and Photoprotective Pigments in Shallow Benthic Communities
Abstract
Our overall goal is to understand how photosynthetic and photoprotective pigments in benthic plants (primarily benthic microalgae) affect the optical properties (primarily spectral reflectance and fluorescence) of shallow benthic environments. The information gained will be used for the development and testing of rapid scanning optical techniques for detecting and assessing changes and specific disturbances in benthic communities. Our main objective is to determine the spatial and temporal (particularly diel) variation in a variety of photosynthetic and photoprotective pigments and examine how these pigments affect the spectral reflectance and fluorescence at the sediment surface. An understanding of these relationships is needed in order to refine algorithms used for processing data collected with various multispectral and hyperspectral imaging instruments used for identification and characterization of both living and manmade objects in shallow benthic environments.
