All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    Description

    Zooplankton were collected during the winter-spring transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. The umbrella net was 2 metres long, 28 cm2 mouth area and mesh size of 100 um. The net was lowered through holes drilled through the pack ice and lowered to 100 m. It was pulled slowly by hand to the surface, closed and brought back through the ice hole. The contents were preserved in 5% buffered formaldehyde and examined under a Leica M12 in the laboratory. Species were identified to the lowest taxon possible.

    Purpose

    Data were used to describe the distribution and abundance of key zooplankton during the winter-spring transition in the pack ice of the Indian Ocean sector. The paper by Wallis et al. (2015) describes the differences and similarities between the data in the 2 years and makes inferences about the role of sea ice thickness in driving zooplankton during that season.

    Quality

    There were no problems encountered with this dataset.

    Australian Antarctic Data Centre Note - 2018-07-04:
    The original datasheet was reformatted to fit IPT Biodiversity.AQ standard. The new datasheet "ZooplanktonSIPEX_I_II.csv" provides the dataset ID, event ID (cruise and station), sampling protocol, verbatim latitude and verbatim longitude that were converted to decimal latitude and longitude (also provided), continent, country, occurrence, basis of record, organism quantity (Abundance in individual per m3), sex and life stage. The taxonomical organisation is provided to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species).
