The analysis includes comparison with various ecological, philosophical, sociological, ethical, theological, and economic schools of thought. His powerful and influential prose and poetry are sampled and savored with respect to their potential impact on solutions for our current grave existential global environmental crisis. His call for an ecological spiritual awakening is interpreted from both religious and secular points of view. Historical relationships between Catholicism and environmental thought are explored. Application to the field of human ecology is considered.
Structural and Functional Aspects of the Ecology of Submerged Aquatic Macrophyte Communities in the Lower Chesapeake Bay Volume I I: Submarine Light Quantity and Quality in the Lower Chesapeake Bay and Its Potential Role in the Ecology of Submerged Seagrass Communities
The teag^oral spectral light environment of shallow areas of the lower Chesapeake Bay was charact... more The teag^oral spectral light environment of shallow areas of the lower Chesapeake Bay was characterized by cosine collection of downwelllnq diffuse Irradianee at 12 wavelengths between 400 and 700 m. An extensive monthly and site coaawrison of spectral attenuation coef f icients Is presented and coaqxared with previous measurements of the light quality environment of the Chesapeake Bay and other estuaries and marine waters Spectral Irradtanee and attenuation of light In a mangrove creek and Thalassla te a tu d lnu m bed of Laguna de Termlrtos, Campeche, Wexlco and the ir relationships to wind-driven suspension of particulate matter, and dissolved substances from the mangrove swaap Is also discussed, A review of the physics of spectral attenuation in estuaries 1s included. Particular attention was given to the relationship between the occurence of seagrasses (Zostera marina mainly} 1n the Chesapeake Bay and spectral attenuation. Potential losses of photosynthetlcally storable radiati...

Wachapreague field station for physical support; Mike Bender for financial support for one of us (R.v.T.) allowing the completion of the analysis of data and writing of this report; Gene Silberhorn for Wetlands Department boat time; Dennis Clark of NOAA for his helpful suggestions and preliminary analysis of the underwater irradiance at Vaucluse Shores; Nancy White and Carole Knox and the V.I.M.S. Word Processing staff for their tireless retyping of endless revisions of this report. Finally and especially we would like to thank our wives, Melissa van Tine and Beverly Wetzel and our children, Tristan van Tine, Paige and Chris Wetzel for thier support and understanding during many long absences in the field, and many long nights and weekends in the lab, at the computer center and during much time spent scribbling on yellow pads.
