TITUSVILLE, FLA. -- Scientists are monitoring Florida's Indian River Lagoon for what some are calling the worst algae bloom in history.
The water is brown and cloudy, and at first appearance, looks more like storm run-off than a rich estuary that supports sea life such as manatees and sea turtles.
Officials with the Florida Fish and Wildlife Commission said the "brown tide" is actually a massive algae bloom. Millions of the tiny organisms are turning the water cloudy almost muddy.
The algae bloom is also killing sea grass on the floor of the lagoon.
Scientists and marine biologists have expressed concern that the algae blooms could result in massive fish kills as well as the loss of other wildlife.
The algae blooms were first reported in the Indian River Lagoon more than a year ago.
