Approach:
These indicators will serve to form the backbone of ecosystem, regional and national-level water quality, habitat assessment and living resources monitoring and modeling efforts. From ecosystem structure and process perspectives, these indicators will be utilized to calibrate and ground truth aircraft and satellite remote sensing of estuarine and coastal resources. Specifically, plant photopigment-based bioindicators will be coupled to high resolution remote sensing spectral analysis of plant community structure, function, physiological and ecological health. These phytoplankton, marsh and seagrass proxies will be linked with metrics of trophic structure to provide indicators of living resources status.
Expected Results:
We will: 1) enhance the rich archive of existing data for these systems with remotely sensed and time-series information on key variables; 2) exploit detailed knowledge of the four well-studied systems to synthesize this archive and develop candidate indicators; and 3) utilize these indicators to gauge ecosystem health and unambiguously detect trends resulting from both natural variability and anthropogenic stresses in multiple estuaries. The present lack of established, regional and national bio-indicators, despite extensive monitoring at thousands of sites nationwide and specific community efforts to develop bio-indicators, is testimony to the magnitude and complexity of the task ahead. We feel that prior efforts toward this ambitious goal have shown that the most promising avenue to success must link theoretical constructs and empirical relationships. We operate on the premise that, "An indicator is a sign or signal that relays a complex message, potentially from numerous sources, in a simplified and useful manner. An ecological indicator is... a measure, an index of measures, or a model that characterizes one or several critical components of ecosystem structure and function.. With a foundation of diagnostic research, an ecological indicator may also be used to identify major ecosystem stress (Jackson et al., 1999)." As it is likely that different types of coastal systems differ in their response to anthropogenic or naturally-induced stresses, we require a framework for assessing status and predicting responses for each of the major system types. The challenge and expected product is to develop concise and accurate representations of ecosystem function and health based on key variables, to detect trends in this health, and to use these indicators to predict the effects of human actions vs. natural variability across a variety of systems, both regionally and nationally.
