Marine and fisheries research

As ocean temperatures rise and circulation patterns shift, the fish populations that billions of people depend on for food are moving, shrinking, or reorganizing in ways that outpace our ability to manage them. Researchers working at the intersection of climate science and marine ecology track how warming disrupts trophic cascades—the chain reactions that ripple through food webs when key species decline—and what those disruptions mean for the productivity of fisheries at a global scale. One pressing open question is how to build management frameworks that can account for ecosystems in flux rather than assuming the stable baselines of the past. Tools like otolith chemistry, which reads the chemical signatures locked in fish ear bones to reconstruct life histories, are helping scientists piece together how individual populations have already responded to environmental change, informing predictions about what comes next.
