Validation at sea Measurement examples in high-transparency waters
Validation contents
Verify the measurement limit in high-transparency waters
Inspection result
Acquire the data on both the water surface and the bottom of the ocean securely
Offshore 400m, deepest about 9m
Validation at sea Surface scan verification
Validation contents
Acquire the topography data of the beach to shoreline shape, and the shape of the sand bar developed parallel to shoreline.
Inspection result
Confirm the seafloor topography (existence of sandbar) in the area where the wave of the sea surface is disturbed.
Sea area: The deepest water depth of about 6 m, the underwater reef, the three-dimensional shape of the curved bar are visualized.
Land area: The step topography is visualized – like the river meandering (as the estuary is obstructed), riverbeds, and shorelines.
Validation at sea Micro-topographical validation in rocky or tongue-shaped sandbars (tombolo).
Inspection result
Confirm the seafloor topography (bathymetry) of the waters developed and formed by tombolo.
Confirm the tombolo offshore 150m offshore.
Confirm the seafloor topography of an area where reefs have developed.
Visualize micro-topography of the rock reef in shallow and complex water areas where it is currently difficult to measure from a ship using existing methods.
Current status of target
Confirm the seafloor topography of an area where reefs have developed.
