Zooplankton distribution and abundance during the BROKE-West survey
Samples were collected at trawl stations (approximately every second CTD station), as well as opportunistically when something interesting was spotted on the Echosounder. The samples were collected with an RMT-1 plankton net and preserved in Steedman's solution. Upon returning to Australia, the...

| Summary: | Samples were collected at trawl stations (approximately every second CTD station), as well as opportunistically when something interesting was spotted on the Echosounder. The samples were collected with an RMT-1 plankton net and preserved in Steedman's solution. Upon returning to Australia, the samples were passed onto Kerrie Swadling, who split them with a Folsom plankton splitter and counted between 400 and 1300 animals. Every organism was identified to the lowest possible taxon - in the case of copepods, usually to species and stage level. Other taxa are to species wherever possible. All the animals were counted and the results are expressed as abundance per 1000 cubic m. The data in the spreadsheet represent a species x site matrix.\n\nThe excel spreadsheet entitled 'List of major samples and activities BROKE West.xls' is a summary of the sort of samples that were collected at each station, and the purpose for which they were collected.\n\nMore detailed notes about the collection of the samples are presented in the Quality field.\n\nFurther information about the Trawl stations can be found in the parent BROKE-West metadata record.\n\nThis work was completed as part of ASAC projects 2655 and 2679 (ASAC_2655, ASAC_2679).\n\nThe fields in these excel spreadsheets are:\n\nStation Number\nSpecies\nDate\nLatitude\nLongitude\nTrawl Type\nFormalin - whether the samples were fixed in formalin\nIGR - whether the instantaneous growth rate experiment was performed\nGenetics - preserved in ethanol, samples retained for genetic experiments\nFrozen - samples frozen at -85 degrees C for chemical analysis\nPOP - samples analysed for Persistent Organic Pollutants\nDensity Contrast - whether the density contrast of the krill were measured\nIsotopes - samples retained for isotope analysis\nFrozen DG - digestive gland samples were frozen\nEthanol (Squid) - ethanol fixed squid were retained\nFrozen (Fish) - frozen fish samples were retained\nFormalin (Fish) - formalin fixed fish samples were retained\nEthanol (Fish) - ethanol ... |
