Descriptor Spanish: Floraciones de Algas Nocivas
Descriptor proliferación de algas nocivas
Entry term(s) marea roja
Scope note: Proliferación de algas en donde producen potentes toxinas que puede determinar una gran mortandad de peces, pájaros, mamíferos e, incluso, provocar enfermedades en los seres humanos. La proliferación de algas también puede causar una disminución de oxígeno en el agua, como consecuencia de la muerte y descomposición de especies de algas no tóxicas.

Scope note: An algal bloom where the algae produce powerful toxins that can kill fish, birds, and mammals, and ultimately cause illness in humans. The harmful bloom can also cause oxygen depletion in the water due to the death and decomposition of non-toxic algae species.

Concept UI M0006483
Scope note A colloquial term for a harmful algal bloom in which DINOFLAGELLATES accumulate rapidly forming dense patches and often discolor the water (but not always red). Some red tides are associated with the build up of natural toxins and some with the depletion of dissolved oxygen. They are unrelated to EARTH TIDES.
