A Map showing the acoustic transect lines and area of focus in the red square plotted over the gridded NASC (m2 nm−2) data. The numbers represent the CTD casts of interest and corresponds to panel C of this figure. CTD casts were conducted from 18/05/2018 to 24/05/2018. B interpolated CTD-derived data plotted along the latitudinal sampling gradient with bathymetry derived from GEBCO (brown shaded areas) and CTD cast number (above each plot) shown for each of the four plots (starting at the top) displaying temperature (°C), salinity, chlorophyll-a (µg L−1) and the corresponding vertical profiles of acoustic measurements of log prey density (individuals per m3) within the area of interest. C CTD transect station locations within the area of interest plotted over 3D bathymetry. The red line represents the reef edge situated along the 50 m contour line of the bathymetry.Logarithms were calculated with basee
