What is an algal bloom?

Algae are naturally occurring plant-link organisms that contribute to wildlife. But when they bloom disproportionately to their ecosystem, they can take away food sources from other organisms.

The algae also can produce a strong odor that smells like rotting plants and toxins that can make animals and people sick.

When blue-green algae is ingested, it can cause rashes, diarrhea, vomiting and even liver problems. Gastrointestinal effects usually begin within 3 to 5 hours after exposure, according to the Centers for Disease Control and Prevention.

These blooms typically happen in the summer or early fall, according to the Florida Department of Health.

Where is the sargassum seaweed blob?

As of February, the swath of seaweed, which reached a record size in December, was still far off the coasts of Florida and the Caribbean.

The University of South Florida monitors, researches and forecasts sargassum blooms in order to eventually be able to predict when it might pile up on beaches.

The most recent report issued Friday showed there is a total of 9 million metric tons of sargassum in the Atlantic, though the researchers predict it won't hit the southeast coast of Florida until late April or May.
