What is a red tide?

    Red tide, also known as algae bloom, is a phenomenon where large amounts of algae gather and cause discoloration in the water. Red tide can result from certain movements in the currents, though oftentimes it’s caused by nutrient loading, which stems from human actions.

    Most species of algae are not harmful, but under certain environmental conditions, some algae, like Karenia brevis, produce toxins, called brevetoxins, that kill millions of fish and other marine organisms. Red tides occur throughout the world, affecting marine ecosystems in Scandinavia, Japan, the Caribbean, and the South Pacific. People who swim among brevetoxins or inhale them may experience irritation of the eyes, nose, and throat, as well as coughing, wheezing, and shortness of breath. Scientists prefer the term “harmful algae blooms” (HABs).
