The Cohen Lab focuses on climate change and its impact on ocean life. We use large coral skeletons to build records of ocean climate to reveal the frequency and extent of its natural variability and give us a long-term perspective on 20th century warming.
In controlled laboratory manipulation experiments, we investigate the impact of acidification, warming and changing nutrient regimes on corals and other calcifying organisms.
Through our expeditions to coral reefs across the Pacific, tropical Atlantic and central Red Sea, we are tracking the impact of a changing ocean climate on real organisms in the real world. And by combining our data with global and regional climate models, we are predicting the impact of future CO2 emissions on coral reef ecosystems across the global tropics.
