Goose-beaked whale acoustic presence from detection of echolocation clicks on single hydrophones at each monitoring site during periods when tracking arrays recorded. Black dots represent percent effort in weeks with less than 100% recording efforts, and gray shading represents periods with no recording effort. Site letter is indicated on each time series. Diagonal black lines across the x-axis indicate a gap in recording effort for 2019.
