Metadata details
SIPEX_II_Microzooplankton
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
This data set includes abundance and distribution of sea ice and water column micro-invertebrates.
Data was collected form 8 stations over the course of the SIPEX 2 voyage. The data for this project consists of 2 separate collection regimes:
1. Ice cores - a number of ice were taken at stations 1-6, using a 15cm corer, they were sectioned and dissolved in filtered seawater before being fixed in formalin. At Station 6 sufficient biomass was present in the bottom 10cm of some cores to allow microscopic separation of copepod species, which were then frozen for stable isotope analysis (SIA).
2. Lazer optical plankton counter (LOPC) was deployed at stations 2 to 7 either from ice holes (IH) or from the trawl Deck (TD) to depths of 60m or 100m. These deployments were made throughout the day where possible and were accompanied by a 100um plankton net . Each deployment consisted of 2 drops for both the LOPC and the net. Collected plankton were filtered onto 50um mesh and backwashed into vials before being fixed in 5% formalin.
All LOPC files .bin will require LOPC program manufactured by ODIM Rolls Royce Nova Scotia.
These files are read to format .dat which maybe opened as a .txt file
