Largely unexplored, and considered among the most hazardous places to dive, the flooded caves, or “blue holes” of the Bahamas, are a potential treasure trove of scientific knowledge. Recently, National Geographic Emerging Explorer Kenny Broad, a diver and advocate for freshwater conservation, led a scientific expedition to these dangerous but fascinating blues holes, making discoveries with implications for fields as diverse as microbiology, archaeology, and even astrophysics.
