James E. Cloern, Brian E. Cole, J.M. Caffrey, A.D. Jassby
1996, Report, 1994 Annual Report: San Francisco Estuary Regional Monitoring Program for Trace Substances
One of the central problems in regional monitoring is choosing a station array that accurately reflects the distribution of values for the entire region of interest. For time-consuming or expensive measurements, an additional goal is to make the number of sampling locations and times as small as possible. These problems...
The developing framework of marine ecotoxicology: Pollutants as a variable in marine ecosystems?
Samuel N. Luoma
1996, Journal of Experimental Marine Biology and Ecology (200) 29-55
Marine ecosystems include a subset in which at least some interrelated geochemical, biochemical, physiological, population and community characteristics are changed by pollutants. Moderate contamination is relatively widespread in coastal and estuarine ecosystems, so the subset of ecosystems with at least some processes affected could be relatively large. Pollutant influences have...
