Sediment Data for Tasman Peninsula, Tasmania

Geoscience Australia carried out marine surveys in south-east Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island.


Seabed sediment samples were collected by TAFI in August 2010 in a targeted area to the east of Tasman Peninsula. Samples were collected at 25 stations using a Van Veen grab, from which a 50 - 100 g sub-sample was taken and submitted to Geoscience Australia for analysis.

Statement

In the laboratory, samples were used for grain size analysis and measurement of carbonate content on separate splits. Grain size measurement was undertaken by wet sieving to determine mud (less than 63 microns), sand (63-2000 microns) and gravel (greater than2000 microns) fractions as percentage of dry weight. A separate sub-sample (~1g) was used for laser diffraction measurement of the mud and sand fractions using a Malvern Mastersizer 2000, with results expressed as percentage of the total particle volume based on an average of three measurements on each sample. Summary statistics include arithmetic mean, mode, standard deviation, skewness and kurtosis. Carbonate content was measured on the bulk fraction only by acid digestion and measurement of resultant pressure, following Muller and Gastner (1979). Sediment data for Tasman Peninsula are a first generation product derived from the physical samples. No transformation of the data has been undertaken.
