Capt. Jonah Martinez and the crew of the M/V Capitana continue to define dispersal patterns within the debris field of the 1715 Corrigan's Wreck, as the 2017 field season gets under way. New diver Ryan Johnson finds 6 musket balls his first time on the 1715 sites. But he didn't stop there. They finished up the day with more musket balls, Olive Jar body sherds, and encrusted artifacts.
