Description 
Summary

The data set comprises Burial Assessments Charts, each consisting of four boxes containing, for a 1km wide corridor: i) detailed bathymetry ii) results of sidescan sonar showing seabed sediments iii) a section showing the sub-bottom profile along the proposed route iv) an indication of the sediment thicknesses within the corridor, not always available v) tensions experienced by the Burial Assessment Tool vi) penetration achieved by the Burial Assessment Tool vii) any other relevant data (such as steep seabed slopes, bedforms seen during the survey, etc.) These surveys were carried out during 1991 along the Atlantic Provinces Cable System in the region of Cabot Strait between Newfoundland and Nova Scotia, the Bay of Fundy between Nova Scotia and New Brunswick, and the Northumberland Strait between Prince Edward Island and Nova Scotia/New Brunswick. These are all in the region of the Canadian Atlantic Maritime Provinces.
