Abstract:

The U.S. Navy has been conducting a long-term monitoring program to examine flora, fauna, and their ecological relationships for possible effects from electromagnetic fields produced by its Extremely Low Frequency ELF communications System. Physiological, developmental, behavioral, and ecological variables for dominant biota in upland, wetland, and riverine habitats near the ELF System have been examined since 1982. Monitoring studies use a split-plot or blocked design to examine differences in space and time. Observations have been made during preoperational, intermittent-use, and full-operational use periods near ELF transmitters located-in Michigan and Wisconsin. Data collection for studies located near the Naval Radio Transmitting Facility NRTF-Clam Lake, Wisconsin, was completed, as scheduled, during 1989. Investigators concluded that there were no effects from intermittent or full operations of the transmitter in Wisconsin. Data collection for studies located near the NRTF- Republic, Michigan, progressed during 1992 and are to continue during 1993. Final results and conclusions for Michigan studies are expected after all data have been analyzed in 1994.
