A knowledge-based geographic information system (KBGIS) approach which requires development of a rule base for both GIS processing and for the geological engineering application has been implemented. The rule bases are implemented in the Goldworks expert system development shell interfaced to the Earth Resources Data Analysis System (ERDAS) raster-based GIS...
Riverine C, N, Si and P transport to the coastal ocean: An overview
David H. Peterson, Stephen W. Hager, Laurence E. Schemel, Daniel R. Cayan
1988, Book chapter, Coastal-offshore ecosystem interactions, Volume 22 of the series Lecture notes on coastal and estuarine studies
Terrestrial ecosystems cycle and recyle inorganic nutrients including a feedback to atmospheric dry deposition and precipitation (cf. Lewis et al., 1985). Each year, however, a small fraction per unit area of the atmosphere/plant/soil flux leaks from these land-based cycles via precipitation/runoff (Meybeck, 1982). These losses are, in general, unpreventable. Moreover,...

Comparisons were based on fish at ages 2–8 recovered with bottom trawls, with gill nets, and...
Relationships of phytomacrofauna to surface area in naturally occurring macrophyte stands
Charles L. Brown, Thomas P. Poe, John R. P. French III, Donald W. Schloesser
1988, Journal of the North American Benthological Society (7) 129-139
Most studies of the relationships between freshwater macrophytes and phytomacrofauna, or the macroinvertebrates associated with the macrophytes, have been based on individual plant collections or samples from monotypic plant stands. We describe the phytomacrofauna assemblages within naturally occurring, taxonomically mixed stands, and consider how macrophyte surface area and plant...
