In some places, this can be hundreds of metres deep on the sea bed. Studying what species are present in the different layers can provide insights into past climate. “Sometimes you have tropical species, sometimes sub-tropical,” van Sebille. “To interpret that data you need to have a baseline, you need to know what's at the surface of the ocean right now.”
