Abstract
A series of seismic and acoustic experiments were carried out at the Spinnaker Array site in April 1997 to determine geoacoustic properties of the ocean bottom and sea ice. Knowledge of these properties is required for reliable acoustic propagation modeling and matched-field processing. The experiments included an ice hammer seismic survey, ocean-bottom seismic refraction and interface wave surveys, and a seafloor reflectivity study. Three different sensor systems were used to measure propagation in the water column, ocean bottom, and ice cover due to impulsive sources deployed in each of these three media. The experiment, together with preliminary and proposed analysis methods, are briefly described in this report.
