A 2004 monograph volume analyzes the tectonic opening of the Tasmanian Gateway from the Eocene/Oligocene boundary onward, impacting ocean circulation and climate over 33 million years. The volume includes research on rift phases, gateway deepening, and Cenozoic marine biostratigraphy in the Southern Ocean between Australia and Antarctica. It was published as Geophysical Monograph Series Volume 151 by the Australian Ocean Data Network.
Use Cases
- Modeling paleocean circulation changes based on gateway opening history
- Analyzing Antarctic glacial development based on stable isotopic sequences
- Investigating tectonic and sea-level interplay from Cretaceous to Eocene sediments
- Studying Cenozoic marine biogeographic development in the Antarctic-Subantarctic region
Strengths
- 344-page monograph volume providing a consolidated research resource
- Focus on a key geological transition (Tasmanian Gateway opening) over a 33-million-year period
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
