Julie, Terry, Gary & David on this single shore entry dive of 105 minutes. Maximum depth 5.9 m, 21 C water temperature and 5 m viz.
A good haul for the river with 26 species of which exactly half are aeolids. Trinchesia sp. 17 is an uncommon species that seems to turn up every couple of years - first time in the river though. We also recorded a juvenile dorid that we are unable to match at this stage.
