Australian Ocean Data Network hosts data from a study of middle to late Eocene calcareous nannofossil assemblages in four sections in the Otway Basin. The dataset compares biostratigraphic events with planktic foraminiferal zones and assesses sedimentation patterns across the basin. The data was last updated on 2026-06-23.
Use Cases
- Correlating biostratigraphic events based on nannofossil appearances and disappearances mentioned in the description
- Assessing diachroneity of marine sedimentation events across the Gambier Embayment and Browns Creek areas
- Comparing local foraminiferal biostratigraphy with tropical planktic foraminiferal zones
- Analyzing sedimentation rates based on thickness variations between fossil appearances
Strengths
- Focuses on a specific geological interval spanning from the middle Eocene to the latest Eocene
- Compares data with a counterpart in New Zealand and tropical planktic foraminiferal zones
- Analyzes four distinct sections within the Otway Basin, providing spatial context
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the Otway Basin study area
