A GoPro Hero 10 actually :) for this one. You can see all the camera details in EXIF, just below the photo in the flickr link.

*Edit - since it was menthioned in one of the other comments, the camera was inside a 50/50 dome, which allowed the equal seperation of the water and the surface. Don't get me started on preparing that thing for "salt water" work, as in frame droplets were a real hassle during the photo shoot.
