High-Resolution Hydrographic Surveys Near the Shelfbreak in the East China Sea: Joint Studies with National Taiwan University

Abstract

For this project, we jointly planned and executed a major field program in the East China Sea northeast of Taiwan. We along with our Taiwanese collaborators performed high-resolution hydrographic surveys over the outer continental shelf and upper continental slope during August/September 2009. The field work was in close collaboration with numerical modelers from MIT who were assimilating the high-resolution hydrographic data into their model and producing ocean circulation forecasts including uncertainty forecasts. During the field experiment, we measured a major fresh water pulse from the runoff from Typhoon Morakot, which caused the most typhoon-related rainfall over Taiwan in 50 years. Our results show strong alongshelf gradients of freshwater at the shelfbreak associated with this freshwater pulse. Our data has been used by the modelers to verify the uncertainty forecasts and the predicted error distribution compares very well with the actual error distribution.
