Book Description
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 data to validate assumptions made in proposals, and selection of study sites. From 1985 through 1987, activities centered on the operation of full-scale studies. This report documents electromagnetic (EM) field measurements at investigator selected study sites from 1982 through 1987. Other engineering support activities are also described. Keywords: Radiation effects, Electromagnetic radiation, Extremely Low Frequency (ELF), Electromagnetic fields, Environmental studies, Ecology, ELF Communications system, ELF Ecological Monitoring Program.

An Evaluation of the U.S. Navy's Extremely Low Frequency Submarine Communications Ecological Monitoring Program
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309055903
Category : Political Science
Languages : en
Pages : 177
Book Description
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.

ELF (Extremely Low Frequency) Communications System Ecological Monitoring Program: Slime Mold Studies
Author:

Languages : en
Pages : 94
Book Description
We have previously shown that continuous exposure of the slime mold Physarum polycephalum to extremely low frequency (ELF) electromagnetic fields (EMF) simulating those generated by the Navy's ELF communication system (then Project Sanguine) could depress the rate of respiration, and lengthen the mitotic cell cycle. In a series of experiments beginning in 1981 and ending in 1987, we sought to determine whether exposing Physarum to the field environment around the Wisconsin Transmitting Facility (WTF) could induce an altered physiological state. A laboratory component was also included to help verify methodology and to supplement studies performed at the WTF. Initially, the experimental effort was directed to devising methods to maintain axenic Physarum cultures under ambient environmental conditions. This involved using growth chambers that admit the electric field or current density from the surrounding environment; the cultures were returned to the laboratory for analysis. The successful methods placed the organism on an agar bed inside double containment and introduced the samples to be assayed into shaken liquid culture medium upon arrival at the laboratory. Both WTF-generated electromagnetic fields and background strengths were measured with the help of IITRI at study locations near the antenna, at the west ground of the WTF antenna, as well as at control sites.
