These ocean dead zones are primarily caused by microbes and bacteria that feed on the algae when it dies. Red tides are caused by a specific type of dinoflagellate, Karenia brevis (K. brevis). Red tide is a naturally occurring, higher than normal concentration of microscopic, single celled, photosynthetic algae. And they can have a serious impact on human health. Red tides are conditions when a dinoflagellate population increases to such huge numbers that it discolors the water. This is non-toxic, but it leads to a lack of oxygen and an increase in ammonia in the water.

The toxins can be suspended in the air near beaches and cause human respiratory illness. Because a red tide is when there is an overgrowth of algae, the causes for algae blooms can vary and depend on a number of factors, which can combine and overlap.

Red tide is a phenomenon caused by algal blooms (Wikipedia definition) during which algae become so numerous that they discolor coastal waters (hence the name "red tide").
