In 1976, the National Park Service initiated a study to determine whether increased boat traffic or boating activities were having an adverse impact on humpback whales inhabiting Glacier Bay National Monument during the summer months. In 1978, the whales entered the Bay as usual, but left sooner than expected. The scientists conducting the whale studies believed that the early departure of the whales was precipitated by increased boat traffic in the Bay and, in 1979, the Park Service, in consultation with the cruise ship industry, developed and implemented operational guidelines for vessel course and speed in designated areas, where it was felt that vessel interactions with incoming whales could cause the most disturbance.
