Oceanography – Message in a Bottle 

Oceanography – Message in a Bottle

Many organisms use “living light”, or bioluminescence, to communicate – a common occurrence in ocean organisms! Bioluminescence is the production of light by a living creature. Our student researchers learned how to subculture a declining population of ocean algae called dinoflagellates! These “dinos” show bioluminescence when exposed to a disturbance (such as waves in the ocean, or simply by swirling their bottled culture). The campers will monitor their cultures all week and then get to take them home (care instructions provided)!!

Ask your camper:  Why do the dinos need a light/dark cycle? (to mimic the natural light/dark cycle which allows them to ‘recharge’ during the light period so they can bioluminesce during the dark period).
