This map of sediment thickness was calculated as a difference between depth to bedrock and depth to the sea floor (bathymetry). The thickest sediment is shown in green while the thinnest is blue. A cross-section was constructed along the pale yellow line and is displayed below the map. The cross-section shows that the bay floor has an irregular bedrock base that has been covered by as much as 90 meters (295 feet) of sediment.
