Description

Diving into the freezing, iceberg-filled waters of Greenland is by itself an adventure, but Museum Curator John Sparks and Research Associate David Gruber recently embarked on an ambitious expedition to find biofluorescent fish in the regions remote waters. Biofluorescence, the ability to convert blue light into green, red, or yellow light, is well documented in tropical fish who live in regions where theres even daylight year-round. But in Greenland, where days can be incredibly long or incredibly short, researchers were interested in seeing first-hand how long periods of darkness affected local fishes ability to biofluoresce. What they found surprised them.#Greenland #ScubaDiving #IceDiving #Biofluorescence #Ocean #Exploration #ScienceThe Constantine S.
