Abstract:
Mesoscale eddies are the most striking feature in the global upper ocean with notable effects on the climate and marine ecosystem. However, acquiring three-dimensional structure of mesoscale eddies remains challenging as their scale is still beyond the resolution capacity of the current generation of global operational ocean observation system. In this study, we conducted an eddy-oriented survey targeting a cyclonic eddy in the Kuroshio Extension during September 2024. Compared to traditional ship-based observations, our survey is synchronized with the newly launched Surface Water and Ocean Topography (SWOT) mission, and complements shipboard measurements with those from 7 autonomous underwater gliders and 20 surface drifters, capturing the eddy's three-dimensional structure with spatially high-resolution and wide coverage. The resulting dataset holds significant value for facilitating the calibration and scientific utilization of the SWOT mission, estimating the eddy transport, and validating eddy-resolving ocean forecasting systems.
