Geoscience Australia Data provides research on the tectonic opening of the Tasmanian Gateway and its impact on ocean circulation and climate over the last 33 million years. The volume includes 344 pages of analysis from the Cenozoic era, covering topics from rift history to marine biostratigraphy. It was published in 2004 as part of the Geophysical Monograph Series.
Use Cases
- Modeling paleoceanographic circulation changes based on the described history of the Tasmanian Gateway opening.
- Analyzing climate change impacts based on stable isotopic sequences from high southern latitudes.
- Investigating tectonic and sedimentary interplay from the Latest Cretaceous to Eocene as described in the volume.
- Studying Cenozoic marine biogeographic development in the Antarctic-Subantarctic region.
Strengths
- Research is based on a 344-page monograph volume providing detailed geological interpretations.
- Covers a long temporal scope, including the Cenozoic era and events over the last 33 million years.
- Focuses on a key geological region, the Tasmanian Gateway between Australia and Antarctica.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic/temporal bias inherent to data_gov_au.
