I am deeply saddened to hear this news. As many have said, Marcia was a wonderful voice of reason. When she responded to questions, or entered into discussions, invariably she would take the time to clarify an issue thoughtfully and with knowledgable insight. Although Marcia and I did not cross paths, I very much enjoyed reading all of her entries.
In a greater sense, I think we are all sort of members of a family. A family which is bound together through a common love for adventure and diving. We have all lost a friend, and a member of our family.
May the Almighty embrace Marcia, and may He provide peace to all the members of her family.
