Short summary
Short summary
The high-resolution autonomous underwater vehicle (AUV) dataset for the South China Sea (SCS) provides 13 491 temperature and salinity profiles and covers 463 d of experiments. To our knowledge, the resolution and length of this dataset are enough to detect the asymmetry, vertical tilt, and temporal evolution of mesoscale eddies (MEs) and the corresponding submesoscale processes. The dataset is expected to improve the accuracy of current and biogeochemistry numerical models. More projects conducting AUV experiments will be promoted in the future.

Short summary
(1) The intensity of the longitudinal estuarine circulation kept increasing as the estuary width continued to decrease.
(2) The changes in water depth were the dominant factor affecting lateral circulation intensity.
(3) The changes in the estuarine circulation were dominated by the changes in the baroclinic pressure gradient force and advection.

Short summary
NIWs (near-inertial waves) have horizontal spatial scales of 10–100 km and slow group velocities, making them to interact strongly with mesoscale eddies. In the northwestern SCS (South China Sea), large portion of eddy propagate westward and may interact with local NIWs. In this study, four moorings were deployed in this area and they captured a vivid case of interaction between a cyclonic eddy and NIWs. Our paper provides direct evidence of strong interaction between eddy and NIWs in the northwestern SCS.
