The survey was completed in 14 days with 8 flight days. The survey was based out of Bangor International Airport in Maine, and covered the Gulf of Maine and Massachusetts Bay area. A total of 42.2 hr were flown, covering over 4,600 mi of trackline. The survey covered the area of the 1991 harbor porpoise shipboard survey in order to get an indication of the fall distribution of harbor porpoise, and surveyed Massachusetts Bay primarily to determine distribution and density of pilot whales during the time of mass strandings on Cape Cod.
