ELF Communications System Ecological Monitoring Program: Electromagnetic Field Measurements and Engineering Support--1989
Abstract
Ecological studies to examine for possible effects to resident biota from operation of the Navy's ELF Communications System continued in Northern Wisconsin and the Upper Peninsula of Michigan during 1989. Monitoring studies were selected through a peer-reviewed, competitive bidding process in mid-1982, and work on most studies began in late summer of that year. Preliminary activities of the Program consisted of site selection, characterization of critical study aspects, and validation of assumptions made in original proposals. Subsequently, increasing emphasis has been placed on the collection of data for treatment/control and preoperational/operational comparison of biological parameters. All data collection near the Naval Radio Transmitting Facility-Clam Lake, Wisconsin was completed by the end of 1989, while data collection at the Naval Radio Transmitting Facility Republic, Michigan is anticipated to continue through 1991. To date, investigators conclude that the electromagnetic (EM) fields produced by either an intermittently energized or a fully operational ELF transmitting facility have had no measurable effects on exposed biota. This report document EM field values at those study sites still active during 1989, and is comprehensive for the period 1983 through 1989. It also describes other engineering activities performed in support of the biological and ecological studies.
