Brief description

The Vlaming Sub-basin Marine Survey GA-0334 was undertaken in March and April 2012 as part of the Commonwealth Government's National CO2 Infrastructure Plan (NCIP). The purpose was to acquire geophysical and biophysical data to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions.

This dataset contains identifications of animals collected from 32 Van Veen grabs deployed during GA-0334. Sediment was elutriated for ~ 5 minutes over a 500um sieve. Retained sediments and animals were then preserved in 70% ethanol for later laboratory sorting and identification (see `lineage'). During sorting, all worms were separated and sent to Infaunal Data Pty Ltd (Lynda Avery) for identification to species or operational taxonomic unit (OTU). Lynda Avery completed identifications on 17 April 2013, and specimens were lodged at the Museum of Victoria. All other taxa were identified to morphospecies at GA by an ecologist.

Gray shading indicates taxa identified to species level by Lynda Avery (Refer to GeoCat # 76463 for raw data of species identifications by taxonomist); all other taxa were identified to morphospecies. Data is presented here exactly as delivered by the taxonomist/ecologist, and Geoscience Australia is unable to verify the accuracy of the taxonomic identifications. Stations are named XXGRYY where XX indicates the station number, GR indicates Van Veen grabs, and YY indicates the sequence of grabs deployed (i.e. the YYth grab on the entire survey). H indicates heavy fraction animals and HS indicates animals found on a sponge. The dataset is current as of November 2014, but will be updated as taxonomic experts contribute.

See GA Record 2013/09 for further details on survey methods and specimen acquisition.

Statement: Samples were sorted under a dissecting microscope (6 - 25 x) and identified in the following manner:

* Polychaete and nematode worms were counted at each station. Due to the high number of fragments, worms were only counted if the head was observed. Lynda Avery completed species level identifications on 17 April 2013, and specimens were lodged at the Museum of Victoria.
* All other phyla (arthropods, bryozoans, sponges, cnidarians, echinoderms and molluscs) were identified to morphospecies by a single observer.

All specimens will be sent to museums for curation and potential further identification to named species. Echinoderms will be sent to Museum of Victoria, molluscs and worms to Museum and Art Gallery of the Northern Territory, and all other phyla to the Australia Museum, as per previous taxonomic collections from surveys GA-322 and GA-325.
