The Washington Department of Ecology has reported a noctiluca bloom in Chuckanut Bay.
The department says they first became aware of the bloom after a citizen scientist sent in photos taken Tuesday.
Oceanographer Christopher Krembs says this bloom may be a first for the region. Over the last 10 years, Krembs says he has not documented a noctiluca bloom in Chuckanut Bay.
Noctiluca is not harmful to humans but it can be an indicator of excess nutrients and possible changes to the food web, oceanographer Juila Bos says.
According to the Department of Ecology, noctiluca blooms occur in the spring and summer when the Puget Sound fills with fresh water from melting snow fueling local rivers.
