Celtic Duet - a joint SACLANTCEN/NRL shallow-water sea trial in Celtic Sea during July 1992: data summary
In July 1992 a joint shallow-water sea trial was conducted in theCeltic Sea by the SACLANT Undersea Research Centre and the US Naval Research Laboratory. The purpose was to obtain monostatic and bistaticreverberation measurements, with supporting transmission loss and environmental measurements. Three sites were chosen: one where small sand waves were deemed to be present, a second where there were large sand ridges, and a third where thin sediment over a chalk bottom was expected. Two ships were used, the NRV Alliance, and the USNS Bartlett. Both ships were equipped with towed arrays and towed projectors. Both ships had vertical arrays and supporting equipment for environmental measurements. A follow-up sea trial obtained additional propagation and geo-acoustic measurements. The report describes the experiments, the ship tracks, and environmental inputs. Some results are shown, including a summary of the waverider analysis carried out at Imperial College in the UK. A few acoustic results are shown, describing checks on the data quality and illustrating representative data for propagation, ambient noise and reverberation.
