Red tide in Florida and Texas is caused bythe rapid growth of a microscopic algae called Kareniabrevis. When large amounts of this algae are present, it cancause a harmful algal bloom (HAB) that can be seen fromspace..
Subsequently, one may also ask, why do red tides occur and what causes them?
Red tide is a phenomenon caused by algalblooms (Wikipedia definition) during which algae become so numerousthat they discolor coastal waters (hence the name "redtide"). The algal bloom may also deplete oxygen in the watersand/or release toxins that may cause illness in humans andother animals.
Similarly, is the red tide in Florida now? The water can even remain its normal color during abloom. No, it is not a new phenomenon.

Furthermore, what is the cause of red tide in Florida?
Red tides are caused by an accumulation ofa type of microscopic organism called a dinoflagellate, which isfound in lakes, rivers, estuaries and the oceans. The particulardinoflagellate that causes Florida's red tide blooms isKarenia brevis.
Is red tide caused by humans?
It is a natural phenomenon, but the exact causeor combination of factors that result in a red tide outbreakare not necessarily known. Coastal water pollution produced byhumans and systematic increase in seawater temperature havealso been implicated as contributing factors in redtides.
