Researchers have compiled a global database to predict rare “milky seas,” a bioluminescent phenomenon where ocean waters glow brightly at night. Using satellite data and historical records, the tool identifies environmental conditions triggering these events, previously shrouded in mystery. The database aids maritime navigation and ecological studies, offering insights into plankton behavior and climate interactions. Early predictions could help scientists study these events in real-time, enhancing understanding of marine ecosystems. The initiative bridges gaps between oceanography and climate science, fostering new discoveries.
