Korean Support for the NRL Component of the US-Korea Collaboration on Mixing Processes in the Southwestern Japan/East Sea

Abstract

The proposed effort provided for Korean support of the US Naval Research Laboratory (NRL) component of a US-Korea collaboration on mixing processes in the southwestern Japan/East Sea (MJES). It complemented a previous NICOP grant (N62909-20-1-2049) to support the Korean component of the scientific collaboration. The overall goal of MJES is to evaluate how small-scale processes impact on the Japan/East Sea (JES) mixing and circulation. Three oceanographic surveys were completed, and this report summarizes how the support was achieved with acquisition of data during the cruises. The overall goal of US NRL's MJES is to study the effect of small scales and submesoscales on the overall circulation and water-mass transformation in the JES. The NRL group intended to achieve the goal by conducting a field observational program designed to measure short-term and long-term turbulent and submesoscale fluxes, bottom frictional drag, pressure (or form) drag associated with the major ocean current, East Korea Warm Current (EKWC), and associated background flow conditions and variability in the southwestern JES EEZ waters. The proposed study area encompasses the southeastern Korean shelf/slope at the southern end of the EKWC, and the downstream area behind Tsushima Island (TI) in the northern Korea Strait, where flow instabilities from mesoscale eddies are generated and the Tsushima Warm Current splits. The objective of the NICOP project is for providing the necessary research vessel platform to achieve the NRL's MJES project goal. Three oceanographic surveys were conducted during the period of 2021 and 2022 using two research vessels.
