The Mooring Component of a Distributed Network of Internal Wave Resolving Arrays to Assess HYCOM Fie
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 redeployable to multiple locations. Each array comprises nine current- and pr,essure-sensor equipped inverted echo sounders (CPIESs) and a densely instrumented central mooring. The CPIES antenna allows for the,detection and separation of low-mode internal waves propagating from multiple directions, while the mooring will measure velocity an,d vertical displacement signals of the first five vertical modes. Five modes are represented in global 1/25 HYCOM tide simulations,(e.g., Buijsman et al., 2020), which provide boundary conditions to regional models used by the Navy. These observations and model f,orecasts can also be leveraged to address acoustic environmental challenges investigated by Task Force Ocean (TFO).This abstract is,publicly releasable.
