So sorry to hear of Mary Ann's passing. Mary Ann was a real bright spot in everyone's day that had the pleasure of working with her at Prudhoe Bay. She was always so busy in the lab but always made the time to say something nice when you dropped off some mystery sample. It has been years since I have worked with her but it was always a pleasure when I happen to bump into her at Costco or somewhere in Anchorage. My heart goes out to her family and close friends. ~ Ben Ball, Anchorage, Alaska
