Crimson tide has dual meaning. The Crimson tide is what it's called when a perticular type of sea weed dies and all comes up on shore (the sea weed is a deep red) this happens along the gulf coast, including Alabama.
The red tide is a phenomenon that occurs when dinoflagellates (algae from the pyrrophyte group) reproduce excessively in the ocean. These algae release toxins that affect the nervous system and can cause death in the marine animals that ingest them and in humans that eat contaminated animals.
