What if everything we need to understand the climate emergency is already written in the ocean? Written in the Ocean is a science journalism podcast series about the ocean and its role in the climate emergency. Through conversations with marine scientists, the series explores the carbon cycle of the ocean, the sediment archives that preserve the climate history of our planet, the invisible processes that keep our atmosphere in balance, the dynamics of glaciers and ice sheets, and the pioneering research that is expanding the boundaries of what we know about the deep sea. Each episode is built...

The water, collected during Expedition 501 of the International Ocean Discovery Program, turned out to be far fresher than anyone expected — reaching levels clos...

MARUM's Core Repository 01.06.2026 15:58

What if the answer to the climate crisis has been buried at the bottom of the sea for millions of years? At MARUM, the Center for Marine Environmental Sciences at the University of Bremen, there is a place that holds more than 200 kilometers of material drilled from the ocean floor. More than 350,000 core pieces. Collected over 55 years of scientific expeditions across the Atlantic, the Arctic, th...
