Rust tide has spread from East Hampton to Riverhead waterways over the past week, posing a threat to marine life in the Peconic, according to the Gobler Laboratory at Stony Brook University.
Rust tide algae, known as Cochlodinium, is more toxic and more dangerous to marine life than the red tide algae that triggered the historic bunker fish and turtle kills last summer…
“When we have extended summer heat as we have seen this summer, a heavy rust tide often follows,” he said.
He [Christopher Gobler, director of the Gobler Laboratory] added that his lab has identified climate change as a major factor in the frequency of harmful algal blooms in local waterways…
High levels of nitrogen in local waterways is a “second, equally important driving factor,” Gobler says…
