Species List: 24-06-2018, Trench, Inner Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld.

29 species sighted at Trench, Inner Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld, 24-06-2018.

Gary and David on this excursion consisting of 1 x 76 minute and 1 x 71 minute dives in water depths from 13 m to 19 m. 15 m viz, 20 C water temp and moderate surge.

Earlier in the week Sunday looked like the most promising day however the weather forecast kept fluctuating and only looked suitable again late on Saturday. We headed for Old Woman Island with the intention of anchoring in the lee just in case the winds belied the forecast again. Unfortunately the swell was quite powerful (long period) which creates uncomfortable surge in shallow waters so, for this excursion we opted to visit a site we have not searched in almost 6 years. Back in 2012 was our last visit here when we were still operating the inflatable. On that visit we recorded 27 species but the viz at that time was only 5 m. Trench is one of our closest sites to the Mooloolah River entrance but still provides good depths to help mitigate the effects of the swell down below. As it happened the wind did not get above 10 knots except for a short period around midday. Today’s excursion turned up some interesting finds, some in pairs, such as: Crimora edwardsi, Verconia alboannulata, Verconia romeri, Diversidoris crocea and Hypselodoris zephyra. Other finds worth a special mention include Actinocyclus verrucosus together with its egg mass and the elegant coloured and patterned Goniobranchus coi. We concentrated our search on the northern wall that drops in a series of terraces to the sandy gutter - a wonderful variety of substrate. Next time we will swim across the Trench and explore the southern escarpment. Altogether a most rewarding excursion at a long neglected site.

Species List: 22-06-2018, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

10 species sighted at, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 22-06-2018.

A single shore entry dive by Gary and David of 55 minutes. Maximum depth 5.7 m, 20 C water temperature (rounded up) and maximum 8 m viz.

A shorter than usual immersion courtesy of a couple of equipment failures. We probably only covered about 10 lineal metres of river bed but managed nevertheless to sight more species than we sometimes record in dives of three times the duration and ten times the distance covered. The substrate has been significantly altered due to the recent river bed profiling operations.

29 species sighted at Terry’s Delight, Arkwright Shoals, off Point Arkwright, Yaroomba, Sunshine Coast, Qld, 16-06-2018

Gary and David on this excursion consisting of 1 x 84 minute and 1 x 76 minute dives in water depths from 13 m to 17 m. 20 m viz, 22 C water temp and no surge.

The ideal surface and diving conditions persisted so we ventured out on back to back excursions, this time a little further afield up to the Arkwright Shoals. A similar species count eventuated but some different species recorded this time. Ardeadoris carlsoni, Chromodoris magnifica and Dermatobranchus sp. 10 were uncommon finds. The deep crevasses at this site provide an enjoyable substrate to search for our elusive quarry.
