Comparison SLA from satellite (orange line) and tide gauge (blue line) 3.2. General condition From 1993-2021, the entire Banda Sea area showed a rising sea level trend (Figure 3). The trend of sea level rise (SLR) in the Banda Sea ranges from 3.8-5.2 mm/yr, with the highest rate near the Lesser Sunda Island (southwestern Banda Sea) and in the northeastern Banda Sea, while the average SLR is 4.36 mm/yr (Figure 3b). This number is slight higher than global mean sea level rise from satellite data (3.3 mm/yr) . In general, Figure 3b shows a strong interannual and annual (seasonal) SLA variability. Regional SLA changes are influenced by global ocean climate events such as ENSO and IOD as stated by , . Hydrodynamic conditions in the Banda Sea are also strongly influenced by seasonal variability . In addition, on the intraseasonal time scale (Madden-Julian Oscillation MJO) also has a role in upper-sea atmosphere dynamics in the Banda Sea and significantly influences local ocean climate variability in that region .
