  1. Summary of the best-fit model for the acoustic presence of humpback whales at stations G3/G4, including SIC, SAM, and month as smooth terms, as well as ONI as a categorical predictor (n = 2629 days of recordings). Note that the factor levels of ONI as a categorical predictor are listed under the parametric coefficients. Segment headings are highlighted in bold.
