Harmful Algal Bloom Forecasts

Texas Satellite Imagery


Composite 8-days of satellite imagery up to 09-17-2023

showing location of algae bloom which may include algae besides K. brevis


Water samples from 09-10-2023 to 09-17-2023 detected Karenia brevis, red tide, along the coast at levels that pose a respiratory irritation risk in Brazoria and Galveston counties.


The image was derived from Copernicus Sentinel-3 satellite data from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and was processed by NOAA, National Centers for Coastal Ocean Science. NOTE: Image quality will vary with clouds and satellite position (OLCI satellite background information). Cell count data were provided by several contributors.
