Short summary
We present the first results from scientific drilling at Darwin Crater, a 816 000-year-old meteorite impact crater in Tasmania. The aim was to recover lacustrine sediments in the crater to reconstruct paleoclimate and bridge a time gap in understanding climate change in mid-latitude Australia. The multi-proxy dataset provides clear signatures of alternating glacial and interglacial lithologies, promising for investigating the role of the Southern Hemisphere westerly winds in Pleistocene climate.
