Mounds of brown, tangled blobs of seaweed, also known as Sargassum, is mixing with plastic and creating a bacteria-laden concoction.

Mounds of brown, tangled blobs of seaweed, also known as sargassum, have been spotted this Spring Break all throughout beaches in South Florida.

TAMPA, Fla. - A record-breaking mass of smelly seaweed stretching from West Africa to the Gulf of Mexico has been identified using satellite imagery. The seaweed bloom, called the great Atlantic Sargassum belt, is the largest ever of its kind, according to a new study. Researchers at the University of Southern Florida used satellite imagery to determine that the giant floating mass of seaweed is a whopping 8,850 kilometers (5,000 miles) long. Scientists first noticed that seaweed was spreading rapidly across the Atlantic and growing in mass in 2011. The seaweed explosion is also indicative of bigger problems, Wang said.
