... surveys are insensitive in detecting irregular topography Water depths between tracklines are not measured so bathymetric contour maps are a result of interpolation between the tracklines. Therefore, any seabed roughness between tracklines can only be qualitatively inferred from other data...

... seismic survey is repeated at specified time intervals, following the same grid of tracklines, using the same seismic systems and a precise navigation system. Time-lapse surveys have been used successfully to monitor the active mudflow about 6 miles upslope from Shell Offshore Inc.' s Cognac Platform...

...-looking sonar images against a cartographic base and display the results in one of 7 standard map projections. Images from adjacent, overlapping tracklines are then computer mosaicked to provide a regional or synoptic display of the seafloor terrain. Introduction Side-looking sonar records or images...

... systems and covering over 6,400 kID of trackline have been examined to identify geologic conditions at or below the seafloor that might affectpetroleum operations. Of the total trackline distance, 865 km were collected in June 1980 aboard the Geological Survey's ship R/V S.P. LEE. The remainder were...
