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

The offshore Tasmanian area, focusing on the Tasmanian Gateway between Australia and Antarctica. This dataset likely contains research interpretations on the tectonic opening of the gateway, its impact on ocean circulation, sediments, and global climate over the last 33 million years. It is a 344-page hardbound monograph from the Geophysical Monograph Series, published in 2004 by the American Geophysical Union.

Use Cases

• Modeling paleoceanographic circulation changes based on the described history of the Tasmanian Gateway opening.
• Analyzing the interplay of tectonics, subsidence, and sea level fluctuations during the breakup of East Gondwana.
• Investigating Antarctic glacial development and global climate change based on stable isotopic sequences from high southern latitudes.
• Studying Cenozoic marine biostratigraphic and biogeographic development in the Antarctic-Subantarctic region.

Strengths

• Focuses on a key geological transition point (Tasmanian Gateway) over a 33-million-year span.
• Presents research from a 344-page monograph published in a recognized scientific series (Geophysical Monograph Series, Volume 151).
• Covers multiple geological phases: rifts, gateway deepening, and post-separation changes.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2026-04-10 17:00:43.161644; freshness should be verified as the core research is from 2004.
