Description

Abstract:

Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave generated currents. Data and samples were acquired using the Australian Institute of Marine Science (AIMS) Research Vessel Solander. Bathymetric mapping, sampling and video transects were completed in three survey areas that extended seaward from Ningaloo Reef to the shelf edge, including: Mandu Creek (80 sq km); Point Cloates (281 sq km), and; Gnaraloo (321 sq km). Additional bathymetric mapping (but no sampling or video) was completed between Mandu creek and Point Cloates, covering 277 sq km and north of Mandu Creek, covering 79 sq km. Two oceanographic moorings were deployed in the Point Cloates survey area. The survey also mapped and sampled an area to the northeast of the Muiron Islands covering 52 sq km. Sample diversity indices calculated in PRIMER (version 6) using the species level data from Carnarvon_infauna(26_Oct_2010).xls

Data quality

Lineage:

Species level data was imported into PRIMER (v6). The diversity analysis was run to calculate: S = species richness N = abundance d = Margalefs index J = Piellous evenness H = Shannon Weiner

Positional accuracy:

Positions were recorded from the same GPS as was used for the multibeam mapping.

Attribute accuracy:

This is a derived data from the species data (Carnarvon_infauna(26_Oct_2010).xls). The attribute accuracy is directly depended on the attribute accuracy of the species data.

Logical Consistency:

The material was treated in a consistent fashion. Samples were sorted by Matthew McArthur, Nathan Whitta and Emma Mathes. All specimens were sorted and all material identified my Matthew McArthur.

Completeness:

Unsorted samples reside in the flammable goods store at Geoscience Australia.
