Seasonal trend decomposition using Loess for sharks detected at Olowalu. Panels from top to bottom show the original time-series data of shark detections (Data – number of individuals detected), the long-term underlying trend indicating an initial increase during the shark tagging phase followed by a gradual decline (Trend), the seasonal component highlighting consistent cyclical variation in shark presence after removing the overall trend (Seasonal), and the residual variability (Remainder).
