ELF (Extremely Low Frequency) Communications System Ecological Monitoring Program: Measurements of ELF Electromagnetic Fields for Site Selection and Characterization - 1983.

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 ELF system areas are being examined. Formulation of an ELF Ecological Monitoring Program was completed in early 1982 by the Department of the Navy. Monitoring studies were conducted through a peer-reviewed, competitive bidding process in mid-1982, and studies were initiated in late summer. Major activities of the program during 1983 consisted of characterization of critical aspects of each study, collection of data to validate assumption made in proposals, and selection of study sites. Measurements of electromagnetic fields at the investigator-selected sites are documented, and the acceptability and status of the sites in light of the electromagnetic exposure criteria are discussed.
