The navigation polyline shapefile shows the track followed by the Canadian Coast Guard ship Frederick G. Creed in the 1998 survey of the Hudson Shelf Valley. The shapefile can be used to identify line spacing, trackline orientation, and the location of data collection. The attributes record the latitude, longitude, date, and time at the start of each line. The tracklines run approximately parallel to the axis of the valley.
