Pro Scuba Training Lets You See the Real Picture


Los Angeles, CA – March 27, 2015 - For a researcher studying past civilizations, pro scuba training can open new horizons for first hand, physical examination of remains and artifacts. Flood waters resulting from the thaw of the last ice age now fill basins that once supported the homes of past civilizations. Caves which thousands of years ago may have provided shelter from the elements now often safely keep the remains of long dead people in watery seclusion. Pictures may be worth a thousand words, but seeing something with your own eyes is much more likely to give you the right words.

In the case of Naia, the 12000+ year old remains of a teenage girl found in a cave in the Yucatan Peninsula in 2007, diving scientists were able to see the scope of the cave with their own eyes. They could see how her skeleton lay in relation to animal bones found in the same location. They saw first hand how the chamber most likely filled with brackish water and what that meant for artifact movement. Photos, while great, can never replace first hand experience when putting together the puzzle of events that occurred long ago.
The water in Naia's cave also preserved her remains far better than anyone expected. Although her bones were mineralized, Naia has proved to be the oldest skeleton found in the New World. She is also the most complete and genetically intact example of early American people found. Naia even had teeth unlike other early American remains.

The Naia discovery is a game changer in understanding the migration pattern of and where the first Americans came from. Our Channel Islands has been and continues to be an important contribution to this mystery with thousands of archaeological sites and important discoveries including the Pygmy Mammal  found recently in 1994 and Arlington Springs woman in 1959, both at Santa Rosa Island. 
Collecting Naia's bones correctly in order to avoid contamination was vital to later testing. Scientists on the dive were able to ensure that proper protocols were maintained instead of trusting others to follow procedure. Floret mineral deposits that might have been destroyed by less knowledgeable hands backed up carbon dating of Naia's tooth enamel to find her age. The tooth enamel alone was not solidly conclusive because of potential mineralization. The secondary test of the florets added needed weight to the findings.
Mitochondrial DNA found deep within Naia's molars was also tested proving that her people had descended from the same line as later Native Americans despite differences in cranial structure. This testing gave scientists another link in the chain of proof linking early settlers who crossed the Bering land bridge from Siberia to modern Native Americans. 

These tests were only made possible by SCUBA divers with the expertise needed to perform a very tricky dive involving multiple passage levels. Cave diving is difficult and requires professional training. Knowing how to swim through very deep, dark tunnels and handle extra gear throughout the process are just two reasons that novice divers should never attempt cave exploration. Fatalities still occur each year, but training greatly lessens the risk.
Today's underwater scientists need to have a variety of tools at their disposal that may seem unrelated to their field of study at first glance.
