Abstract : A long-term program for studying possible effects from the operation of the Navy's ELF Communications System is being conducted on biota and ecosystems components in northwestern Wisconsin and the Upper Peninsula of Michigan. Sixteen general types of organisms from three major ecosystems in the ELF system area are being examined. Formulation of an ELF Ecological Monitoring Program was completed in early 1982 by the Department of the Navy, and studies were initiated in late summer of the same year. Beginning in 1983 and continuing during 1984, major activities of the program consisted of characterization of critical aspects of each study, collection of each study, collection of data to validate assumptions made in proposals, and selection of study sites. 1985 and 1986 activities centered on the operation of full scale studies. This report documents electromagnetic (EM) field measurement at investigator selected study sites from 1982 through 1986, and presents the status of the sites in light of the EM exposure criteria. Other engineering support activities are also described. Keywords: Extremely low frequency; Electromagnetic fields; Environmental studies; Ecology; Communications system.
