Confounded by flounder in South Australian waters
During a walk through the shallows at Glenelg North beach after 9.30 pm last night, in knee-deep water, Emma and I were delighted to spot a numbers of small (likely juvenile) flounder. The animals were each less than 10 cm in length and sported fine, uniform sandy patterns which allowed them to practically disappear on pale, sandy bottom. When startled by our lights or movement, the animals escaped swiftly, hugging the contours of the sandy ‘dunes’. On settling, they would sometimes shuffle into the…

Nocturnal observations around Glenelg marina and jetty
While this weekend’s scorching hot temperatures kept my wife and I out of the sun for the most part, we couldn’t resist making a late night beach walk down at Glenelg. While the habitats there are highly modified due to breakwater and marina construction, dune removal for coastal development plus stormwater, Patawalonga and treated wastewater inflows, there remains an abundance of life to be observed by anyone with an eye for detail and a nice bright flashlight. Emma and I…

Common Sawshark & Green Sawfish sightings off Glenelg
Sawfish and sawsharks are very rarely sighted by divers in South Australian waters. Diver Alex Suslin had an exciting encounter with a Common Sawshark, Pristiophorus cirratus at the Glenelg Dredge about 9am on 13th November 2014. He described the event as the first sighting of one he’d made in almost 20 years of diving. Alex estimates that he had dived that site approximately 100 times before. “It was heading towards the Dredge at a great rate of knots, but I couldn’t find it there. It…

Oil spills in St. Vincent’s Gulf in 1992
According to a report in The Advertiser earlier this year (1992), there had been a series of three oil spills at Port Stanvac over just a few months. The second spill resulted in a large fire. The third spill came from a rusty pipe on the refinery wharf. 400 litres of diesel caused a slick several hundred metres long and extending up to 1 kilometre out to sea. The refinery said that this spill posed no threat to the shoreline…
