AAS_4600_Cetacean_acoustic_presence

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 product contains acoustic presence and absences of cetacean species derived from the acoustic recordings made from sonobuoys deployed during the TEMPO voyage. The information in this data product is a spreadsheet containing one row for each sonobuoy deployed, and one column for each type of vocalisation that was detected.

    Acoustic data were converted into a spectrogram, and these were manually inspected (visually and aurally) by an expert familiar with many different types of commonly detected sounds from cetaceans. Presence and absence of all sounds of each type were given a single score for each sonobuoy.

    Scores in each cell correspond to analyst's certainty of the presence of that species. Scores range from 0-4 indicating:
    4: Analyst certain that call type was present
    3: Analyst believed calls quite likely present (with reasonable certainty)
    2: Analyst thought calls could possibly have been present (but some uncertainty)
    1: Analyst thought calls may have been present (but not very certain)
    0: Call type was not detected by analyst
    blank: Analyst did not inspect for this call type

    Purpose

    This data product was produced to provide a synoptic overview of cetacean species (top predators) that were acoustically detected during the 2021 TEMPO voyage. It is intended to complement other work done on the TEMPO voyage to understand the distribution of top predators in the vicinity of krill.

    Quality

    Data quality are good. Sonobuoys that failed or had data quality issues are noted in the column 'Failure'. Issues with data quality for these sonobouys are described in the notes where appropriate.
