Metadata details

ASAC_40_BROKE

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).

    chemtaxres.xls contains concentrations of Chlorophyll a (micro g.L-1) for each depth at each station, allocated by CHEMTAX software between 8 algal groups:
    Table contains data for:
    CTD, lat, long, depth, and the amount of Chlorophyll a allocated by CHEMTAX software between the following algal groups:
    Prasinophytes, Dinoflagellates, Cryptophytes, Hapto3s, Hapto4s, Chlorophytes, Cyanobacteria, Diatoms

    chemtaxintegres.xls contains the total concentration of chlorophyll a at each station (mg.m-2), integrated to 150m depth, as allocated by CHEMTAX software between 8 algal groups. Data include CTD, lat, long, and integrated Chl a in the following groups: Prasinophytes, Dinoflagellates, Cryptophytes, Hapto3s, Hapto4s, Chlorophytes, Cyanobacteria, Diatoms, as well as the percentage contribution by each group.
