Elliot Peters and I on this single shore entry dive of 124 minutes. Maximum depth 6 m, 25 C water temperature and up to 3 m viz.

Nice cruisey dive finding nudibranchs. Elliots first dive in the river, he was impressed. What was of interest was the number of very small Hypselodoris obscura. In the 3-5 mm range.And yet again Goniobranchus daphne was everywhere.
