Short summary
Short summary
This study investigates coastal currents over a bank along the southern coast of Korea, focusing on their asymmetric response to alongshore wind stress. Variability is larger in the western region of the bank, driven by enhanced cross-shore sea level gradients associated with Ekman transport over bank topography. The asymmetry remains robust despite offshore currents and changes in wind conditions.

Short summary
This study presents a new method to improve the accuracy of sea level height from the Ieodo Ocean Research Station in the East China Sea. The method helps identify data errors, such as repeated or unusual values, and flags extreme weather events. The analysis found that sea level rise is mostly due to ocean mass changes, with local ground subsidence also playing a role. These high-quality data support research on short- and long-term events, helping coastal monitoring and planning efforts.
