Tectonic and Climate History of the Tasmanian Gateway from Deep Sea Cores

A 2004 monograph with 344 pages investigates the tectonic and climatic evolution of the Southern Ocean from the Late Cretaceous to the Neogene. The volume, published by the American Geophysical Union, focuses on the opening of the Tasmanian Gateway and its impact on ocean circulation, sedimentation, and Antarctic glaciation. It incorporates results from deep-sea cores and stratigraphic investigations at high southern latitudes.

Use Cases

• Modeling paleoceanographic circulation changes based on the described tectonic gateway opening.
• Analyzing the relationship between tectonic subsidence and sea-level fluctuations described for the Cretaceous-Eocene period.
• Studying Cenozoic marine biostratigraphic development in the Antarctic-Subantarctic region between Australia and Antarctica.

Strengths

• Published as a 344-page volume in the peer-reviewed Geophysical Monograph Series.
• Focuses on a specific, long-term geological process (33 million years of gateway development) with multi-disciplinary research.
• Incorporates stable isotopic sequences described as rarely available for high southern latitudes.

Limitations

• The dataset appears to be a published book (HTML format), not a structured data table; column-level documentation is absent.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• Last updated metadata is from 2026-06-27, but the underlying publication is from 2004; freshness should be verified.
