Zooplankton samples were collected during the winter-spring transition in the Antarctic sea ice zone on two research cruises. The data likely contains species abundance counts identified to the lowest taxon possible, collected using a 2-meter umbrella net lowered to 100 meters. Samples were gathered by the Aurora Australis vessel during SIPEX (2007) and SIPEX II (2012) expeditions.
Use Cases
- Analyze seasonal zooplankton community composition based on species identification data
- Study the impact of the winter-spring transition on Antarctic marine life based on the temporal sampling context
- Model zooplankton abundance in sea ice habitats based on the specific geographic and environmental collection method
- Compare interannual variability in plankton populations between the 2007 and 2012 sampling events
Strengths
- Collection method is precisely documented: a 2-meter umbrella net with a 100 um mesh size lowered to 100 m
- Samples were collected during two distinct expeditions (SIPEX 2007 and SIPEX II 2012), providing temporal comparison points
- Species were identified to the lowest taxon possible, suggesting detailed taxonomic resolution
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
