The First- and Second Island Arc Turbulent Eddy Regional Exchange - ARCTERX
Abstract
We propose an ocean sensing and synthesis program to address goals of the ONR Department Research Initiative (DRI) - Island Arc Turb ulent Eddy Regional Exchange (ARCTERX). The area of study, the Western Pacific between the 1st and 2nd island chains, is a region synoptically characterized by four major current systems (Kuroshio Current, Mindanao Current, North Equatorial Current, and North E quatorial Counter Current) and is known for strong meso and submesoscale variability. A complex submesoscale cascade is the result of a variety of processes including flow-topography interactions, typhoon and monsoon forcing, and instabilities of the major curren t systems that generate filaments, fronts, and eddies. Our proposed efforts will build off previous work in the region and will rel y on the deployment of persistent autonomous sampling platforms and the development of advanced autonomy behaviors to collect upper ocean physical oceanographic data in submesoscale features of interest, with objectives of increasing predictability. The proposed autonomous systems for use in this program include USVs (Liquid Robotics SV3 Wave Glider), UUVs (REMUS 600), and air-deployable expe ndable directional wave drifters (Scripps GPS-based Miniature Wave Buoy). Our effort will build off experience in both ONRs AUMA a nd FLEAT DRI programs. As in previous DRIs, we anticipate close collaboration with other observational groups, and numerical model ing teams to address issues of downscaling-model fidelity, parameterizations, and assimilation. Partnerships with operational Navy including NAVO, UUVRON, CTF75 (Guam), NSW, and INDOPACOM will be fostered.This abstract is publicly releasable.
