Understanding, enjoying and caring for our oceans
In December 1875, a submarine communication cable ran from Normanville to Kingscote on Kangaroo Island. Society member and local resident, David Muirhead sent us the following details and photographs concerning the cable: – The spot where the communication cable to Kangaroo Island ran into the sea at Normanville (Taken by […]
I’ve always been flummoxed by the trend whereby divers who live in Adelaide continually revisit a handful of the state’s innumerable shore diving locations. While the popularity of Rapid Bay jetty, the rocky reefs of Second Valley, the soft coral encrusted columns of the Port Hughes jetty and the built […]
I took this ‘one off’ shot of a clear jelly during my dive at Moonta Bay jetty in June 2017. While the photograph is enigmatic, my observations were sufficient for me to pursue a positive identification of the species. It turned out to be a comb jelly, and my interest […]
A small group of Society members were able to stay at the Moonta Bay Beach Villas over the weekend recently, thanks to the kindness of Peter Anastassiadis. We were supposed to be a bigger group, but half of the group cancelled out at the last minute due to cold or […]
David Muirhead says that the Normanville jetty is “a pretty poor excuse for a jetty”. “I have, however, found some surprisingly good photographic subjects on the piles at high tide, which is all the more titillating given the entire jetty can be above the water mark,” he says. (The present […]
I love to see “my wheels” when I dive at Second Valley jetty. It’s great when I come across them during my dives there. I’m talking about large cartwheels and ‘truck sets’ that are in the bay between the jetty and ‘boat shed island’. I described these wheels in my […]
We held a dive at the Port Hughes jetty on 2nd January. We were doing a dive that had been postponed from the previous month.We had heard that many juvenile Southern Gulf Pipefish, Stigmatopora narinosa were being seen at the jetty at the time. The divers on the day consisted of Peter Gower, Chris […]
We dived at Rapid Bay jetty (for the third time in five weeks) in early December. Our dives all comprised a mixture of Society members and one or two ‘ring ins’. Each dive was completely different to the other two. This latest dive, on 5th December, consisted of some five […]
In my recent article “My Love Of Jetties, Some Of My Jetty Work, Granite Island Jetties & A List Of S.A. Jetties Built During the 1800s Or Early 1900s” I wrote about the Granite Island Causeway and the Victoria Pier there at Victor Harbor. Some of those details included: “The […]
I am a research associate at the California Academy of Sciences where I study the evolutionary relationships among seahorse, seadragons, and pipefish in the family Syngnathidae. I employ DNA sequencing, morphological characters, and underwater photography to gain a better understanding of these relationships which are largely unresolved in this family, […]
