Importance of Blue Holes





Blue holes pose significant historical importance because their geologic formations and oxygen void water preserve much from the past. These caves formed in a time when sea levels were much lower but as sea levels raised the caves became flooded with seawater. Because this seawater lost oxygen and has unique chemistry the skeletal remains of many ancient organisms have been preserved in these caves and remain undiscovered. Extinct species, however, are not the only species that are of interest in the caves. Blue holes boast unique biodiversity of microbial and multicellular life. Studying these organisms is important because of the unique harsh conditions they survive in which can show us more about life on earth and beyond. In addition, the geologic formations of the blue holes can be studied to better understand past climate change as well as sea level rise. This information could prove invaluable as global warming and sea level rise continue to be critical issues in today’s world. Blue holes are like time capsules from the past that lack in any significant study and we hope to be the ones to unlock their secrets.
