Lucieer, V and Pender, A, An environmental assessment of a proposed marine farming zone west of Wedge Island, South Eastern Tasmania, Institute for Marine and Antarctic Studies, University of Tasmania, Hobart, TAS (2014) [Contract Report]
The initial assessment survey captured twenty sediment grab samples across the zone. In this initial survey one sample contained a live specimen of the native screwshell, Gazameda gunii. This was positively identified by the Tasmanian Museum and Art Gallery Zoology Department and therefore, following the Marine Farm Assessment protocol, a further twenty grab samples were collected across the site. Gazameda gunii was identified in 3 of the additional 20 samples.
An interesting feature within the site was the presence of localised depressions in the sediment on the eastern boundary. These depressions were found at 47 m depth and were on average only 1 m lower than the surrounding seafloor. The sediment composition differed to the surrounding sand as these pockets were comprised of gravel and coarse sand with shell grit.
