‘It can kill you in seconds’: the deadly algae on Brittany’s beaches

For decades, potentially lethal green algae have amassed in shallow bays on Brittany’s beautiful north-western coast. Environmentalists say the blossoming of unusually large amounts of green algae are linked to nitrates in fertilisers and waste from the region’s intensive pig, poultry and dairy farming.

Tracking Sargassum’s ocean path could help predict coastal inundation events

New research explores how the Sargassum might grow while it is meandering along the currents, not just where it floats, combining both ocean physics and seaweed biology for the first time to understand the distribution patterns. Knowing could eventually help predict its arrival and impact on beaches around the world

Scientists testing new solution to fight Florida’s toxic red tide

The state of Florida is at war with a toxic red tide. A tide that is killing marine life along the Sunshine State’s southwest coast and creating a stench. Scientists at Mote Marine Laboratory in Sarasota are working on a new weapon that they call an “Ozone Treatment System.

What is a red tide?

Harmful algal blooms pop up nearly every summer, turning coastal waters red and creating problems for marine life and humans.

Seaweed farming and its surprising benefits

Increasing numbers of fishermen, scientists, and foodies in the country are starting to look at seaweed as a promising source of food, jobs and help cleaning ocean waters.
