Excited that this paper, led by former PhD student Natalia Varela (based on her dissertation), is now out!
We use the occurrence & characteristics of thin, silty turbidites from the Ross Sea to interpret Antarctic Bottom Water outflow since ~3.3 Ma.

A great week in Wellington at the International Sedimentological Congress where I presented my Miocene record of bottom water changes at ODP Site 1123. I enjoyed learning about all of the research being done using sediments from around Aotearoa and connecting with researchers from NZ and overseas.

Great study that provides insight into ocean oxygenation during a past warm climate 🤩
🚨New paper out with @alexauderset.bsky.social! We show that the Arabian Sea oxygen minimum zone (OMZ) was better oxygenated during the warm Miocene Climate Optimum than today, but its path to full deoxygenation was slow and complex.

We’ve wrapped up drilling at Crary Ice Rise with 228m of sediment core. This is an unprecedented record of the history of the West Antarctic Ice Sheet stretching back millions of years. Initial observations indicate the core includes periods of environmental change during past times of warming.
