Husson University chemistry professor Ray Kennard (pictured at left) and archaeological conservator Molly Carlson recently conducted air sampling and analysis to help museum staff learn about chemical changes in the St. Mary hull section during its 40 years in the museum (the hull exterior is partly visible in the upper left of this photo) .
Kennard and Carlson diagnosed “shipwreck disease,” a common condition that causes deterioration due to the chemical effects of iron and wood that have been buried underwater. With this knowledge, museum staff can better plan for the St. Mary’s continued preservation, in part through the new air handling and ventilation system that is currently being planned for installation next year.
