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

by

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…

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

by

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…
