Mineralogy data collected from the CEAMARC-CASO voyage of the Aurora Australis during the 2007-2008 summer season. The data consist of a large number of images, plus documents detailing analysis methods and file descriptions.

Mineralogy sampling method:
(numbers in brackets refer to image below)
Individual bags containing the samples taken during the CEAMARC 2007/08 voyage (1) were emptied in to a sorting tray and slightly defrosted to enable the biota to be separated and sorted in to like biota (2). Taxonomic samples were selected to represent different species. The taxonomy sample was moved onto the bench and allocated a STD barcode, a photo was taken (3) and the image number, barcode and 'identification' of the biota was recorded. From the taxonomy sample a small (larger than 0.05g) sample of the individual was dissected, weighed (4) and bagged separately, this sub-sample became the 'mineralogy sample' that were sent to Damien Gore at Macquarie University on 21/05/2009 for mineralogy analysis by Damien Gore and Peter Johnston.
Samples were tracked using the Sample Tracking Database (located \aad.gov.au\files\HIRP\new-shared-hirp\30 Samples tracking + LIMS (Lab Inf Management Sys)\Sample Tracking Database\HIRP STD Working). The key barcodes are:
The nally bin's containing the CEAMARC samples are located in reefer 1 (-20 C) (barcode 11919). The original CEAMARC samples (parent container) are in nally bins 14762 and 14759. The taxonomy samples are in a nally barcoded as 70469 (contains 10 bags). The mineralogy samples are in a nally bin barcoded 70472 (contains three bags) and are currently at Macquarie University for mineralogy analysis.
Data was entered during the lab process into the spreadsheet file - Sub sampling taxonomy and mineralogy.xls the details of the spreadsheets contents;
The list below describes each column in the 'Taxonomy and Mineralogy', 'bamboo coral' and 'other analyses' sheets from the excel file - Sub sampling taxonomy and mineralogy.xls (location described in G:\CEAMARC\CEAMARC MINERALOGY FILE DESCRIPTIONS.doc)
Date sampled
Date that the taxonomic samples were dissected to obtain the mineralogy samples
Parent barcode
STD barcode for the nally bin that the samples are located in
Site barcode
STD barcode for the CEAMARC site and deployment
CEAMARC site number
CEAMARC voyage sample site number
CEAMARC event number
The CEAMARC voyage event number is the sampling devices deployment number, related to CEAMARC site number
Taxonomy bag barcode
STD barcode for the bag that contains the taxonomy samples
Image number
The image number of the taxonomy sample in it's entirety before dissected to obtain the mineralogy sample. Image contains the label from the initial sample and the sub sample barcode (for taxonomy)
Sub sample barcode (for taxonomy)
The STD barcode allocated to the taxonomy sample
Analyses label for mineralogy
The number (identical to sub sample barcode number) that identifies the mineralogy sample and links it back to the taxonomic sample.
Analysis sample weight
The weight in grams of the dissected part that is the mineralogy sample.
Mineralogy bag barcode
STD barcode for the bag that contains the mineralogy samples
Identification
Biota sample identification eg. Gorgonian, bryozoan, ophiuroids
Mineralogy sample size
Relative size of sample sent off for mineralogy analysis; small sample, medium sample or large sample.
Taxonomy sample size
Relative size of sample small sample; medium sample or large sample (suitable for further analysis).
The 'KRILL' sheet in the above excel file has the following columns;
Date sub sampled

Image number
The image number of the taxonomy sample in it's entirety before dissected to obtain the mineralogy sample. Image contains the label from the initial sample and the sub sample barcode (for taxonomy)
Sub sample barcode (for taxonomy)
The STD barcode allocated to the taxonomy sample
Analyses label for mineralogy
The number (identical to sub sample barcode number) that identifies the mineralogy sample and links it back to the taxonomic sample.
Analysis sample weight
The weight in grams of the dissected part that is the mineralogy sample.
Mineralogy bag barcode
STD barcode for the bag that contains the mineralogy samples
Identification
Biota sample identification eg. Gorgonian, bryozoan, ophiuroids
Mineralogy sample size
Relative size of sample sent off for mineralogy analysis; small sample, medium sample or large sample.
Taxonomy sample size
Relative size of sample small sample; medium sample or large sample (suitable for further analysis).
Voyage
The ANARE Voyage number and year is expressed as V4 02/03
Station
Station number that the samples were obtained from
Date
Date that the samples were taken during the voyage
Time
Time that the samples were taken during the voyage
Location
