NASA's PACE satellite captured spectacular imagery of the Black Sea showing enormous turquoise-colored areas caused by a massive phytoplankton bloom. These microscopic marine organisms contain pigments that can dramatically change the color of seawater when their concentrations become extremely high.
Phytoplankton are responsible for producing roughly half of Earth's oxygen through photosynthesis, making them fundamental to the global carbon cycle and marine food chain. However, unusually large blooms can also consume oxygen when they decay, potentially creating dead zones that threaten fish and other marine organisms.
NASA's PACE mission uses advanced ocean-color instruments to monitor these biological changes across the world's oceans from orbit.
