The CPIES Component of a Distributed Network of Internal Wave Resolving Arrays to Assess HYCOM Field

Abstract

Through the Defense University Research Instrumentation Program (DURIP), we propose to obtain in-situ instrumentation that will coll,ect high-frequency internal wave measurements in the deep ocean near the shelves for skill-testing and comparison with the global HY,brid Coordinate Ocean Model (HYCOM). This DURIP proposal and a companion Scripps Institution of Oceanography-led DURIP will instrume,nt three internal-wave resolving (IWR) arrays that are re-deployable to multiple locations. Each array comprises nine current- and p,ressure-sensor equipped inverted echo sounders (CPIESs) and a densely instrumented central mooring with a surface buoy. The CPIES an,tenna allows for the detection and separation of low-mode internal waves propagating from multiple directions, while the mooring wil,l measure velocity and vertical displacement signals of the first five vertical modes. Five modes are represented in global 1/25 HY,COM tide simulations (e.g., Buijsman et al., 2020), which provide boundary conditions to regional models used by the Navy. These obs,ervations and model forecasts can also be leveraged to address acoustic environmental challenges investigated by Task Force Ocean.
