The IVAR system (Intensity Vector Autonomous Recorder) is a bottom deployed system developed for first-use in the Sediment Characterization Experiment (SCE17), conducted on the New England Mud Patch [40°28’ N, 70°35’ W] in spring 2017. IVAR continuously and coherently records four channels of acoustic data, three from a tri-axial accelerometer embedded in a neutrally buoyant sphere (diameter 10 cm) and one from an omnidirectional hydrophone positioned 10 cm above the centroid of the sphere positioned 1.2 m above the seafloor. Despite operations being significantly impacted by two Gale-force storms, IVAR obtained 72 h of data over 2 deployments that included low frequency signals from a towed source (J-15) deployed from the R/V Endeavor and broad band SUS charges deployed from R/V Neil Armstrong. Interesting features of the intensity (Umov) vector field emerge in both bandwidth regimes, but here we focus on measurements of the 100 + SUS charges. The measured Umov vector for each SUS charge is first compared with the known source bearing, and is followed by an analysis of precursor arrivals and dispersive water-borne arrivals in the context of the received vector field. The source locations provide complementary information on range and azimuth dependence of the sediment properties.
