ELF (Extremely Low Frequency) PVS (Propagation Validation System) Field Strength Measurements, March 1977.
Abstract
From September 1976 to December 1978, extremely low frequency (ELF) field-strength and effective-noise measurements were taken aboard operational submarines. The results of measurements taken in Connecticut and aboard two submarines during March 1977 are discussed. Particular attention is focused on simultaneous Connecticut and North-Atlantic area measurements where nighttime propagation anomalies occurred 2 to 4 hr apart. A prime candidate for the cause of these anomalies is a moving nocturnal sporadic E-layer. (Author)
