New England Shelfbreak Front "PRIMER" Experiment: Acoustic Results
Abstract
LONG-TERM GOALS. Our goal is to understand the propagation of low-frequency sound (10-1000 Hz) from the continental slope to the continental shelf including the effects of the ocean processes and bathymetric features that are associated with the shelfbreak. This understanding is key to achieving accurate sonar prediction in a shelf-slope littoral environment. SCIENTIFIC OBJECTIVES. The acoustic objectives of the Shelfbreak PRIMER field study, which took place in a shelf-slope region south of New England, are: (1) To determine the effects of seasonal and mesoscale variability of the shelf-break frontal thermal structure on the transmission of sound from the slope to the shelf. (2) To relate the temporal and spatial variability of the acoustic propagation with the ocean variability in the frontal zone. (3) To obtain tomographic maps of the frontal region for use in the characterization of the ocean variability.
