To See the Oceans Glow

Scanning Electron Microscopy of dinoflagellates from

You may have heard of a red tide before…If not let me remind you it generally occurs  when there has been an a exponential growth in the number of dinoflagellates in the water column often referred to as a ‘bloom.’ The water often turns a golden or red color under these conditions, it also creates a  condition where other organisms are unable to survive due to nutrient depletion (sometimes including oxygen).

Despite these inhospitable conditions other types of these organisms  produce a bioluminescent display that is spectacular.  When disturbed these unicellular creatures light up in the ocean waters. This makes boating under evening conditions  remarkable. I hope to one day witness this this oceanic beauty.
