Jervis Bay Infaunal species level dataNote: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703016176 Title: Jervis Bay Infaunal species level data CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments (for textural and biogeochemical analysis) 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 Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG. Sample/species matrix of infaunal taxa derived from Van Veen grab samples taken on the HMS Kimbla surveys GA0312 and GA0315 in Jervis Bay. ANZLIC search words:

Access constraints: This material is released under the Creative Commons Attribution 3.0 Australia Licence Free Data DownloadData qualityLineage: Sediment samples were taken from the HMS Kimbla using a Van Veen grab. Returned sediments were washed on a half millimetre sieve. Retained material was preserved in ethanol. Preserved material was sorted under a dissecting microscope and the animals were identified and enumerated. Log of edits carried out on Jervis Bay infaunal data (winter) 1) Data was recorded using the beta test version of Biotally while processing the samples. No data sheets were generated. Daily backups were made to an external hard drive and stored separate to the laptop housing the software. Positional accuracy: Positions were recorded from the same GPS as was used for the multibeam mapping. Attribute accuracy: The names applied to the taxa are mostly nominal. There is scope for the names to be updated as museum taxonomists make identifications and write descriptions. 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: All available samples were processed.
