What’s the big deal about sedimentary ancient DNA? By Ana Gomes, Research Fellow, NORCE/Bjerknes Centre for Climate Research and Joline Lalime, Sea2SchoolAU Most people don’t get excited about mud – but for us, there is nothing more satisfying than a long, continuous, and well-preserved sediment core. What looks like ordinary mud is actually a layered

New model correction improves predictions of Antarctic ice shelf melt Accurately predicting how Antarctic ice shelves melt is critical for understanding future sea-level rise and global climate change. A recent study led by ACEAS PhD researcher Claire Yung from the Australian National University introduces a correction to ocean models that could significantly improve these predictions.
