Abstract :

Sea Surface Temperature (SST) Is An Important Oceanographic Parameter That Plays A Major Role In Atmosphere–ocean Interactions And Influences Regional Ocean Dynamics. Variability Of SST In Tropical Regions Is Strongly Affected By Wind-driven Processes Such As Vertical Mixing, Ekman Transport, And Upwelling. The Southern Waters Of Banyuwangi, Located In The Eastern Indian Ocean, Are Influenced By Seasonal Monsoon Systems And Exhibit Complex Oceanographic Conditions. However, Studies Examining SST Variability In This Region By Integrating Surface And Subsurface Parameters Remain Limited. Therefore, This Study Aimed To Analyze The Influence Of Wind Forcing On SST Variability In The Southern Waters Of Banyuwangi Using SST, Surface Wind, And Vertical Density Profile Data. SST Data Were Obtained From The Operational Sea Surface Temperature And Sea Ice Analysis (OSTIA), Wind Data Were Derived From ASCAT Products, And Density Profiles Were Calculated From Temperature And Salinity Datasets. The Analysis Was Conducted Using Spatial–temporal Approaches, Hovmöller Diagrams, And Pearson Correlation Analysis. The Results Showed A Clear Seasonal SST Pattern During 2025, With Warmer Conditions (>29 °C) Occurring During January–May And October–December, While Lower SST Values (~26–27 °C) Occurred During June–September. The Cooling Period Coincided With Increased Wind Intensity During The Southeast Monsoon Season, When Wind Speed Reached Approximately 5–6 M S⁻¹. Density Profiles Showed Upward Displacement Of Isopycnal Layers During June–September, Indicating Shoaling Of Denser Subsurface Waters Toward Shallower Depths. Pearson Correlation Analysis Revealed A Moderately Strong Negative Relationship Between Wind Speed And SST (r = −0.68), Indicating That Stronger Winds Were Associated With Lower SST Conditions. These Findings Suggest That Monsoon-driven Wind Forcing Plays An Important Role In Controlling Seasonal SST Variability In The Southern Waters Of Banyuwangi Through Wind-induced Vertical Ocean Processes.
