The U.S. Navy established an ecological monitoring program to determine whether electric and magnetic fields from extremely low frequency (ELF) communications systems influenced plant and animal populations near the transmitting facilities. Although some of the researchers believe that a few biological changes might have occurred, they concluded that the results do not indicate significant adverse ecological effects.
This book evaluates the 11 ecological studies of the Navy's monitoring program and examines the adequacy of experimental design, the data collection and analysis, and the soundness of the conclusions. It also addresses whether the monitoring program was capable of detecting subtle effects due to ELF exposure and examines the biological changes observed by some program researchers, such as enhanced tree growth.
The US Navy has an extremely-low-frequency (ELF) communications system that transmits from the Great Lakes region using electric and magnetic fields (EMFs) to communicate with submarines around the world. This report evaluates the Navy's long-term ecological monitoring of its communications system, with emphasis on review and evaluation of study designs, analyses of data, and interpretations of results of the Navy's program.
