a, b Intensity and AoP images captured at 14:00 local time for different sites and water depths. c, d Intensity and AoP images captured at 17:00 local time for different sites and water depths. Note that in the intensity images, the sky is clearly visible in high-visibility waters at a shallow depth (4th column). However, it is not visible in low-visibility waters (1st column) or at greater depths (5th column)
