Carnarvon Shelf species level infauna data
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.

Data log for Carnavon Shelf infauna: Sediment samples were taken using a Smith McIntyre grab. Sediment was washed on a half millimetre sieve and the retained material was preserved in ethanol. Preserved material was examined under a dissecting microscope and the animals were identified and enumerated. 20/8/10: Output from Biotally generated. Opened in PRIMER as abundance data with samples as columns. Data check function used to identify: duplicate samples (none) duplicate variables (many) all zero samples (none) all zero variables (none) negative values (none) missing values (none) Duplicate variables seem to be a problem for outputting large data sets from the Biotally database. The duplicates were checked against each other and against the data as it resides in Biotally. When it was confirmed that each duplicate was the same as others with the same name, and that they all mirrored the information originally input, the duplicate variables were selected and deleted. 23/8/10: Afternoon in the lab checking reference specimens and image library. Compound microscope examination of the material allowed the following coalescences to be made in the infauna data: Apseudomorpha_sp1 (a mislabelling) into Apseudomorpha_sp5. Gnathiidae_sp2 into Gnathiidae_sp1 (false split due to sexual dimorphism). Lovenia_elongatus into Heart_urchin. 27/8/10: Day in the lab verifying counts and identifications on the following samples: 003GR01 009GR02 012GR01 015GR01 021Gr01 030GR02 045GR01 074GR02 076GR01 078GR01 080GR01 098GR02 100GR01 177GR02 The identifications and counts were consistent between the original data and the check. No ammendments were made. 13/9/10: Haliophasma removed from data in PRIMER: count coalesced into Anthuridea_sp15. Periclemines removed from data after examination of the single specimen saw it coalesced into Caridea_sp1. 15/9/10: Misskeys: Tanaidacea_sp5_C136 in sample 022GR02 identified as a miskey. After checking the specimen its count was moved into Tanaidacea_sp1 where it belonged and the erroneous taxon was removed from the data. Ophiuroidea_sp3 was not found in 085GR01, but was a specimen of Ophiuroidea_sp13. Count was moved, taxon was removed. Ostracoda_sp8 did not occur in 083GR02. Identified as and count moved to Ostracoda_CS17 and erroneous taxon was removed. Ostracoda_sp9 did not occur in 095GR02. No specimen found in sample vial. Taxon removed from data. Count not reallocated. Anthuridae_sp10 was a miskey for Anthuridea_sp10 in sample 030GR02 (yes, they are spelt differently) and a similar problem occurred for Anthuridae_sp11 and Anthuridea_sp11 in sample 117GR03. In each case, the count was moved and the erroneous taxon was removed. 15/9/10: OTU level data set sent to Hideyasu and Piers Dunstan for checking. 15/9/10: Family level aggregate data set generated using taxa sheet: OTU to Family. Functional level aggregate data set generated using taxa sheet: OTU to function. 20/9/10: Sand descriptions from sampling log added as factors to PRIMER data set.
