Sampling strategy: Samples from trawls or sledges are sieved on the trawl deck then sorted in the wet lab per taxonomic group. Sorting may vary from high taxonomic levels (order, family) to specific ones according to expertise on board. For some taxa, sampling includes: up to 10 voucher specimens with a unique batch number; photos; tissue samples in 80% ethanol for DNA analysis (Barcoding and Phylogeny); 30 samples minimum for population genetics (for abundant species); sampling for isotopic measures; fish chromosomes preparations; primary fish cell lines and cryopreservation of fish tissues for permanent cell lines The database was intended to contain information about stations, events, gear, all material collected and associated samples listed above. currently only contains information on material collected and samples. Data was recorded on log sheets then transcribed into an Oracle database called cabo. Tailor made user interace for entering data. No export functionality. SQL database dump has been provided but there was no-one on the voyage to elaborate on the structure, this was promised post voyage along with some simple data exports to match the log sheets, so we have access to the data without the unfriendly database.
