As part of the NSF-funded Processes driving Exchange at Cape Hatteras (PEACH) Project, 5 current- and pressure-sensor equipped inverted echo sounders (CPIESs) were deployed along the continental slope spanning the “separation location” where the Gulf Stream veers away from the boundary and crosses isobaths as it passes over the Deep Western Boundary Current and flows into the ocean interior. The CPIESs were deployed on AR15 and were successfully recovered 19-months later on AR33. The acoustic travel time records from these bottom-moored instruments document variability at scales that cannot be resolved by satellite altimetry and help us understand processes that drive Gulf Stream variability.
