RECONNAISSANCE DATA The portrayal of the seafloor on this chart is based on two types of reconnaissance data:
1) Single depth measurements taken at 2 Kilometre intervals.  The shape of the seafloor between the depths is unknown.
2) Depths from ships' tracks.  In this case the accuracy is uncertain and no information about depths on either side of the track is available.
