She, Rolland, Wasser and their other colleagues have only had such an opportunity once, and it was not one they expected or would have hoped for. In the days following 9/11, both plane and ship traffic were disrupted. Rolland and her colleagues happened to be studying right whales that month in the Bay of Fundy, which lies northeast of the coast of Maine. “After September 11, we decided to continue our work despite what had happened,” she says. They took acoustic recordings of the bay, collected whale poop, and perused ship traffic logs.
