Red Tide, also referred to as Harmful Algal Blooming (HAB), occurs when phytoplankton that contains reddish pigments, “blooms” or grows very rapidly and becomes visible from the surface of the water. These blooms can be harmless, or can contain toxins that can cause the death of sea creatures. This phenomenon can also cause adverse reactions in the human body, through skin and respiratory irritation or through food poisoning (if an affected shellfish is ingested). Red Tide (which has no association with real tides) can be problematic for costal economies if seafood production is shut down, or if beaches are not available for use by tourists. I decided to study Red Tides after viewing dead fish that had washed up onto the beach and hearing the annoying coughs of my fellow travelers during my recent vacation in southern Florida.
