ANZIC Forum 2022 Talk: Deep-sea hiatuses track the vigour of Cenozoic ocean bottom currents

By Adriana Dutkiewicz Abstract: Scientific ocean drilling data collected over half a century have generated a treasure trove of data to map deep sea currents.  We have compiled data from more than 200 drill sites to map the continuity of the deep sea sedimentary record and to understand how global warming– or cooling – is … Read more…

When the Earth warms, the ocean speeds up

Sixty-six million years of geological data suggests that heating makes ocean currents stronger. By Ellen McPhiddian, Cosmos Ocean currents play a big role in floods, droughts, and other large-scale weather patterns. We know that ocean circulation will be affected by global warming – but figuring out exactly how it will be affected is much more difficult. Will there be … Read more…

Geology: Deep-sea hiatuses track the vigor of Cenozoic ocean bottom currents

The deep-sea stratigraphic record is full of gaps. These hiatuses track changes in ocean circulation and chemistry, but determining their timing and causes has been limited by sparse data and incomplete knowledge of ocean gateway evolution in earlier studies. We combine a significantly expanded, age-calibrated deep-sea stratigraphic database with a global tectonic and paleo–water depth … Read more…

PhD scholarship in Deep-Sea Sediments and Paleoclimate

This PhD project with Dr. Adriana Dutkiewicz in the Univ. of Sydney EarthByte Group is aimed at reconstructing the evolution of the deep-sea carbon reservoir and its impact on the long-term global carbon cycle as part of an ARC-funded Future Fellowship. It includes a stipend allowance of $28,854 per annum for three years (with an … Read more…
