Abstract : This was a DURIP project to acquire a suite of inverted echo sounders (lESs) equipped with pressure and current sensors (CPIESs). CPIESs are moored instruments that measure the round-trip acoustic travel time between the seafloor and the sea surface; bottom pressure and temperature; and near-bottom horizontal currents hourly for up to 5 years. Using an array of CPIESs- particularly when leveraged with other remote sensing and in situ observations- allows for investigations of ocean physics at a range of spatial and temporal scales. The goals of this project were to enhance the pool of pressure-sensor equipped lESs available at the Woods Hole Oceanographic Institution (WHOI); to foster partnerships between WHOI, other US groups, and international collaborators; to promote data analysis methods that combine CPIESs measurements with other in situ and remote sensing observations; and to promote developments of the CPIESs and related technologies. CPIESs obtained through this program are presently deployed in the equatorial North Pacific as part of the Flow Encountering Abrupt Topography (FLEAT) Department Research Initiative (DRI).
