Noctiluca bloom in Chuckanut Bay may be a first


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.
