Whales, Plankton and bioluminescence


Whales, Plankton and bioluminescence

If you spend a night of rising moon on the beaches of Cala Gonone (especially after a day of sirocco) you'll notice one of the most charming events that occurs in the seas with an high concentration of phytoplankton and other microorganisms: the bioluminescence, an optical phenomenon that occurs at the contact with water, observable in calm sea conditions. A night dive in a plankton sea will cause the reaction of the microorganisms, a phosphorescent light which will give you one of the most beautiful baths of your holiday.

The depth of the water and the upwelling, due to the presence of many submarine springs, favour the ion exchange in the most superficial layer of the sea (euphotic zone) for the bacteria development and the consequent development of plankton, where cetaceans go to feed. The whale sightings are becoming more frequent in the Gulf of Orosei and it is not uncommon that you can admire them during one of the daily cruises.

The Blu Best Association will organize for you a day of "whale watching".
You can contact the guides in the Sea Charter section for a day in the Gulf of Orosei.
