Marine Traffic Data for the Port of Boston.
Abstract
Data was recorded on marine traffic in the Port of Boston and on VHF-FM marine communications channel usage in the Port of Boston during the period 13 to 20 September 1976. The marine traffic data was recorded by means of time lapse photography of the display of a radar whose antenna was located at the north-eastern corner of Commonwealth Pier 6, which is at 42 deg 21 min 6 sec North, 71 deg 2 min 14 sec West. The radar recordings were analyzed to compile statistics on marine traffic in the area. The maximum number of simultaneous movements observed at this site was 30. This was observed on Sunday, 19 September 1976. Recordings were made of communications on VHF-FM maritime mobile channel 13 and 16 as received at the same site. These recordings were analyzed to compile statistics on communications activity. Channel 13 had about a 3 percent daily utilization rate, while channel 16 had an 8 percent rate. (Author)
