An experiment to study radio propagation in the Arctic maritime environment was undertaken in Canada in 1982. Five UHF radio paths between pairs of elevated points were selected along a 300 km east-west line which parallels a potentially important navigation route through the Arctic islands. Two VHF paths, each between an elevated site and a point near sea level were also chosen to simulate communications with a ship. Partial results from the summer-to-winter transition season show that propagation between the elevated points is highly reliable, but that propagation along the slanted paths appears to be strongly affected by radio-wave ducting.
