Red Tide Causes Big Stink Along Local Beaches

For the last two weeks, an algae bloom has dazzled crowds and lit up waves in Southern California. But now, scientists say it’s turning deadly for some fish, and they want to know why.

Changing the (Red) Tide: Experts to Discuss Cause, Impacts of Algal Blooms

“I didn’t know what was happening — the water, usually clear and blue, was brownish red and murky.” Emily Pomeroy, a program manager with Save Our Shores, recalled a visit to Monterey’s Del Monte Beach in the summer months of 2019. “I’d heard of red tides before … but I had never seen one in person,” she said. These periods of discolored water that Pomeroy had stumbled upon can be called a “red tide” though in reality they are better known as a “harmful algal bloom.” They occur when water temperatures and nutrient levels rise, Pomeroy learned, and often lead to devastating consequences for marine life and those who depend on it.
