[AOS12-08] A Tale of Sea Level Dynamics in the Arabian Gulf
キーワード：Sea Level, Satellite Altimetry, Seasonality, Arabian Gulf
The Arabian Gulf region has one of the busiest shipping lanes and plays a very important role in transporting oil. Furthermore, major settlements along coastal areas of the Arabian Gulf are vulnerable to sea level rise. So, studying sea level variability can not only assist in understanding the local ocean dynamics but also provide valuable insight that can assist in the planning and management of coastal infrastructure. In this research, I use all the available satellite altimetry data (1993 to 2023). I evaluate the sea level variability along the entire profile that covers both the Arabian and Oman Gulf and delineate both seasonal and trend components. The data shows there is an out-of-phase relationship between the Arabian and Oman Gulfs with a phase lag of six months which seems to be driven by wind velocity reversal. Furthermore, it is found that like the first-order Fourier series, simple sine functions can also model the seasonal component of sea level in this region.
