Streaks of red tide - a toxic algal bloom that threatens marine life - were clearly visible in Noyac Bay during a flyover on Thursday.
Aerial photographer Jeff Cully captured images of red tide lining the shore at Long Beach.
Red tide has appeared in Long Island waters every summer since 2004, Chris Gobler, Ph.D., told Patch earlier this month, when the algal bloom made its first showing of the year.
