Manuhangi

Manuhangi, a small oval-shaped atoll, is located approximately 100 km to the south-southwest of Hao.
The atoll encloses almost the lagoon. Though there is a narrow passage on the south of the atoll, its depth is considerably shallow. Therefore, the quantity of seawater by the tide is not clear. As a result, the concentration of salt of its waters seems to be a high level.
