- Abstract:
- A pilot study yielded strong evidence for restructuring of the hydrography in the Australo-Antarctic Gateway and the Tasman Sea immediately following the Mi-1 event of the earliest Miocene. We propose to improve the resolution for stable isotopes, carbonate content and sortable silt. Reduced sample spacing for low-sedimentation Sites 1170-1172 will provide sufficient detail to firmly establish trends, and inter-site differences. Closer sampling at Site 1168 will allow astronomical dating of the observed changes. Comparison with isotopic and Sortable Silt data from Sites 1090 (S. Atlantic) and 1124 (SW Pacific) will be used to establish the relationship between opening of the AAG, SW Pacific and Drake Passage. Moderate resolution benthic foram assemblage work will constrain deep hydrographic changes inferred for the AAG.
