Southern Ocean data contains krill larvae counts per cubic meter for three species: Euphausia crystallorophias, Euphausia superba, and Thysanoessa macrura. Measurements were collected at multiple oceanographic stations during the 2005-2006 BROKE-West research voyage. The dataset was produced by the Australian Antarctic Data Centre (AU_AADC) as part of ASAC projects 2655 and 2679, with data published in 2006.
Use Cases
- Model krill species distribution (Euphausia superba, Euphausia crystallorophias, Thysanoessa macrura) based on sampling station locations.
- Analyze larval abundance (counts per cubic meter) to estimate population density and recruitment success.
- Compare relative abundance metrics between the three krill species across the surveyed stations.
- Correlate krill larvae data with concurrent oceanographic measurements from the BROKE-West voyage.
Strengths
- Data for Euphausia superba is peer-reviewed, published in a 2006 scientific paper by Kawaguchi et al.
- Covers three distinct Antarctic krill species, allowing for comparative analysis.
Limitations
- Sample size (number of stations or rows) is unknown, limiting statistical power assessment.
- Data for two species (Euphausia crystallorophias, Thysanoessa macrura) are unpublished, pending future paper.
