The following data was taken by the Early Warning System (EWS) team of the New England Aquarium (NEA) from 12/05/96 through 02/05/97. The Sighting Number reflects all EWS sightings listed in consecutive order so sightings in which "Rat" was not sighted are not included. The sea state is in the Beaufort Scale (see below table) and the Site Distance is in nautical miles. The latitude and longitude are recored in decimal equivalents of degrees and minutes.

The position data received is sometimes in decimal fractions of a whole degree, such as 30.50N degrees. To obtain the degree and minutes equivalent, multiply the decimal fraction times 60 minutes/degree, such as .50 x 60 = 30 minutes. In the case of 30.50 degrees, this equals 30 degrees and 30 minutes.
