Data was collected on the marine traffic and VHF-FM marine communications channel usage at Mobile, Alabama, during the period of 23-30 January 1978. The marine traffic data was recorded by means of time-lapse photography of a radar display. Recordings were made of the communications on VHF-FM maritime mobile Channels 13 and 16 as received at the site. The daily average of marine traffic, including large, medium, small and anchored vessels, and tugs-in-tow, transiting the main ship channel and Intracoastal Waterway is 95. Approximately 150 hours of communications on VHF-FM Channels 13 and 16 were recorded and monitored to determine channel efficiency (i.e., percentage of valid messages) and utilization. Channel 13 efficiency is 61.35%, utilization 2.46%. Channel 16 efficiency is 43.18%, utilization 5.86%.
