The dive

A tidal inland blue hole with fairly salty surface water and a very shallow halocline (Smart 1984). It is a popular swimming spot with locals, and a university uses the hole for freshwater field classes.

Profile and sections

A tidal inland blue hole with fairly salty surface water and a very shallow halocline (Smart 1984). It is a popular swimming spot with locals, and a university uses the hole for freshwater field classes.

It was explored by Cousteau's team (Wikipedia). A 2020 study describes a 'Little Frenchman' with cave passages to 127 m some ~68 km to the south; which of the two rightly bears the name is unclear.

Depth and profile
~37 m deep and ~12 m across (Southern Adventist University); the tourism site gives -127 m, but that figure probably belongs to the cave passages of another 'Little Frenchman' blue hole further south · very shallow halocline
