Learn about the single-celled coastal algae that create this glowing phenomenon when they’re disturbed. N. scintillans populations can exhibit high concentrations due to high concentrations of the plankton on which they feed, which are likely due to environmental conditions such as well-mixed, nutrient-rich waters, seasonal circulation, and runoff from agricultural pollution.
