Short summary
Today, the waters north of Iceland are characterized by high productivity that supports a diverse food web. However, it is not known how this may change and impact Iceland's economy with future climate change. Therefore, we explored how the local productivity has changed in the past 8000 years through fossil and biogeochemical indicators preserved in Icelandic marine mud. We show that this productivity relies on the mixing of Atlantic and Arctic waters, which migrate north under warming.
