Model performance evaluation with (A) Area Under the Curve (AUC) and True Skill Statistic (TSS) scores, with the selected models highlighted by bold circles; (B) specificity and sensitivity scores; and (C) contributions of environmental predictors. Models are color-coded by algorithm. 'Salinity_ltmax refers to the long-term maximum salinity, 'temp_mean' to the mean bottom temperature, and 'o2_ltmin' to the long-term minimum oxygen level.
