Eddies and the Kuroshio between Luzon and Northeastern Taiwan: Integration of In Situ Observations and Remote Sensing Data
Abstract
This is a proposal to examine the mean and time-varying transport and velocity structure of the Kuroshio east of Taiwan and to assess the effect of mesoscale eddies on the circulation here. The analysis will be conducted using in situ data from shipboard measurements and from 2-year long records collected with moorings comprising six pressure sensor equipped inverted echo sounders (PIESs) and three acoustic current Doppler profilers (ADCPs). These in situ data were obtained through a recently completed field program, carried out as a joint U.S.-Taiwanese collaboration through the Observations of Kuroshio Transports and Variability (OKTV) Program, which is sponsored by the Taiwanese National Science Council (NSC), and the ONR-sponsored Origins of the Kuroshio and Mindanao Currents (OKMC) DRI. In addition to processing and analyzing the in situ data from the moorings, the efforts described in this proposal will focus on integration of the observations with (1) other data sets collected through the OKMC and OKTV programs, (2) historical data from the western North Pacific, and (3) concurrent remote sensing data. The objective of the data analysis proposed here is to understand how variability in the Kuroshio east of Taiwan is related to upstream variability east of Luzon and at the North Equatorial Current bifurcation. Furthermore, the proposed analysis will examine how westward-propagating mesoscale eddies, generated in the North Pacific Ocean interior, shape Kuroshio variability when they arrive along Taiwan. The long-term goal of the completed field program east of Taiwan and the analysis proposed here is to improve understanding and predictability of the regional circulation in the western North Pacific.
