Description
Zooplankton were collected during the winter-spring transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. As part of the collections sea ice cores were collected to describe the ice habitat during the period of zooplankton collections. Ice cores were taken with a 20 cm diameter SIPRE corer and sectioned in the field with an ice core. Temperature was measured in the section using a spike thermometer and slivers of each section were melted without filtered water to record salinity. The remainders of each section were melted at 4oC in filtered seawater and the melted water was used to measure chlorophyll a concentration, and meiofauna species and abundance. Meiofauna were counted and identified using a Leica M12 microscope: to species in most cases and down to stage during 2012.
Quality: No problems encountered with data collection. Australian Antarctic Data Centre note - 2018-07-03: The original datasheet was reformatted to fit IPT Biodiversity.AQ standard. The new datasheet "IceCoreMeiofaunaSIPEX_I_II.csv" provides the dataset ID, event Id (Cruiser), sampling protocol, verbatim depth, event remarks, event date, verbatim latitude and longitude that were converted to decimal latitude and longitude (also provided), continent, country, occurrence, basis of record, life stage, and organism count. The taxonomical organisation is provided to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species). Some corroborating information from this dataset have been included - https://data.aad.gov.au/metadata/records/AAS_4140_Environmentaldata
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 2,442 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
