Follow-up on the Schooners Lemael & Booya

I had previously written a series of articles regarding a number of sailing ships, but two in particular – the Booya and the Lemael. The series started with “Cyclone Tracy Shipwrecks” in our April 2005 newsletter (No.320). This was followed by “More About the Booya” in our July 2005 newsletter (No.323). The third article was titled “The Wreck of the Schooner Lemael” and it was published in our June 2007 newsletter (No.344). The final one in the series (until now)…

What Is CIGESMED for Divers?

In November 2013, I hosted Vasilis Gerovasileiou from Greece during his visit to South Australia. We only managed one dive together though. We managed a dive at Rapid Bay jetty on16th November 2013. Vasilis had only brought a 5mm wetsuit with him for his dives in Australia. This suit probably served him well for dives in WA & Queensland, but it didn’t work out so well for his dive in SA. The water temperature at Rapid Bay in November was…

MLSSA replaced the SA Museum Underwater Research Group

Our Society celebrated its 40th anniversary this year. Next year we can celebrate our 60th! That’s if we take the word of our Patron & Life Member, Dr Scoresby Shepherd. He says that MLSSA, formerly MARIA (SA Branch), followed on from the SA Museum Underwater Research Group. The Museum URG was established in 1957. It was part of many international URGs which commenced in France in 1945 (meaning that we indirectly reached our 70th anniversary last year). The first URG was established…

Follow-up re Sea urchin barrens and mini-barrens

Further to my article titled “Sea urchin barrens and mini-barrens” (http://wp.me/p4BvtZ-pZ ), Society member, David Muirhead commented, “Magazine Bay looks so nice Steve. I can see why you dived that day rather than sat on the beach reading a magazine (or waiting for one to explode)!” David then added, “PS: the only barrens or minis I’d seen in my early diving days were in Fiji and those were uncommon, but here in SA it is only in the last few…

Victorian marine worm I.D.

Early April 2016, we received an email message with the subject heading “Possible new species”. The message read (in part), “I was just went down Shoreham Beach with my family for a walk through the reef and stumbled across a strange creature. We were able to get a good quality video of it and thought I could send to you. We have previously sighted it three years ago at Mushroom Reef but wasn’t able to get it to any professionals….

The naming of the Bluefin Leatherjacket, Thamnaconus degeni

David Muirhead took this photo of a male Bluefin Leatherjacket, Thamnaconus degeni, at the Noarlunga Tyre Reef: – Photo of a male Bluefin Leatherjacket, Thamnaconus degeni (Taken by David Muirhead at the Noarlunga Tyre Reef) The leatherjacket was named by a Mr C Tate Regan in 1902 (or 1903).
