Noctiluca scintillans Red Tide in Bouzas

Today, August 29, we were informed at the Oceanographic Center of Vigo about the observation of a red tide on the beach of O Adro, in Bouzas (Vigo). It looked like, and it was, Noctiluca scintillans, a heterotrophic dinoflagellate that usually forms red tides on our coasts during this season of the year. The pictures were taken between 9: 30-9: 45 in the morning, while the tide was going down, under calm and sunny weather. In this link you can see an underwater video. As you will see, the cells were concentrated in a thin surface sheet. The values ​​of salinity in the red spot of Noctiluca were very low, between 12-15.
