Last week, our colleagues Sara Hardardottir (HAFRO, Iceland) and Sofia Ribeiro (GEUS, Denmark) published a new study on using ancient DNA of a specific sea ice algae to reconstruct past climate change in the Arctic. A few years ago, Sara and Sofia came to our lab in Bergen to further develop this DNA-based method that detects the sea ice dinoflagellate Polarella glacialis (see pictures) in marine sediments. We hinted in… Read More »Reconstructing sea ice history with Polarella
