"Manuel Iturralde, research director of Cuba's Natural History Museum, has joined Canadian exploration company Advanced Digital Communications (ADC) in efforts to solve the mystery of the smooth, geometrically shaped, granite-like rocks. They are laid out in structures resembling pyramids, roads and other structures at more than 600 meters deep (2,000 feet) in a 20 km-square (7-3/4 mile-square) area."

MSNBC: ADC plans to take a specially designed robot to the site in a few months to take samples of the rocks and the sediment they are embedded in to try to date them and seek signs they may have once been on dry land. They will also be searching for any sign of human life such as drawings, sculptures or artifacts. ''To drill samples from these structures is not easy because they look like granite. And to drill granite at a depth of 600 meters is very difficult,'' Zelitsky said.

Electric Warrior: It appears that the videotape is being analyzed by the Marine Archaeology and Anthropology Center of the Cuban Academy of Sciences. The experts' work is centered around the inscriptions found on the stones, which were undoubtedly made by humans. It has been proven that the stones were cut and dressed to fit one another and form larger structures.

Very little is known about the inscriptions, except that they are numerous and are found practically throughout the underwater site. Symbols and drawings of unknown significance have also been found.
