Mineralogical composition; Sediment grain size parameters; Sediment acoustics; Side-scan sonar; Sediment water content, porosity and surface area; Geological sample density; Bathymetry and Elevation

Sidescan sonars; single-beam echosounders

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.) This survey was carried out during 1993 along the Celtic Cable Route from Sennen Cove, Cornwall, UK to Kilmore Quay, Southern Ireland.
