Mesoscale — Small Scale Oceanic Variability Effects on Underwater Acoustic Signal PropagationRange (CDR) estimates. These profile measurements are usually tasked to one ship or aircraft and support centre, which then provides regular reports, disseminated throughout the force. Rapid Environmental Assessment (REA) methodologies have been developed towards the optimization of the ADR and CDR

Intra- and Inter-Regional Geoacoustic Variability in the Littoral to investigate geoacoustic variability within a region and variability between two regions, extensive geoacoustic and acoustic measurements were conducted in two areas in the Italian littoral. While it is not surprising that significant geoacoustic and acoustic variability is observed in each regio

Acoustic and , Techniques for Measuring the Spatial Variability of Seabed Geoacoustic Parameters in g acoustic interaction with the seabed is particularly important in shallower water environments as the propagation typically involves extensive interaction with the sea surface and seabed. DRDC Atlantic is developing acoustic and . techniques for seabed classification and measuring geoacoustic para

Measurements of Bottom Variability During Swat New Jersey Shelf Experimentsw Water Acoustic Technology (SWAT) experiments at the New Jersey Shelf. Chirp sonar (2–12 kHz) data were used to invert bottom geoacoustic properties with sub-meter resolution. Sediment properties such as density, porosity and sound-speed profiles are inverted from coherent acoustic returns at sever
