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

A 344-page geophysical monograph from 2004 synthesizes research on the opening of the Tasmanian Gateway. It addresses the tectonic history from the Late Cretaceous and its impact on ocean circulation, sedimentation, and global climate over the last 33 million years. The volume is published by the American Geophysical Union and incorporates results from deep-sea cores collected offshore Tasmania.

Use Cases

• Modeling past ocean circulation changes based on the described history of the Tasmanian Gateway opening.
• Studying Antarctic glacial development linked to tectonic events described in the volume.
• Conducting biostratigraphic correlation using Cenozoic marine fossil records from the Antarctic-Subantarctic region.
• Analyzing the interplay of tectonics, subsidence, and sea level during the breakup of East Gondwana as discussed.

Strengths

• Volume is 344 pages, providing substantial textual analysis.
• Focuses on a specific, high-latitude geological region (Tasmanian Gateway) over a defined 33-million-year period.
• Published as part of the authoritative Geophysical Monograph Series (Volume 151).

Limitations

• The primary data format is HTML, suggesting the dataset may be a document rather than structured data tables.
• Row count and column definitions are unknown, limiting suitability assessment for quantitative analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
