While seismic ships study subterranean strata, hydrographic survey vessels focus directly on measuring ocean depth, seafloor
contours, and coastal topography. Utilizing multi-beam echo sounders and precise satellite positioning systems, these vessels
sweep wide swaths of the seabed to collect highly detailed bathymetric data.

The resulting measurements are critical for creating accurate nautical charts, identifying submerged navigational hazards, and
supporting dredging projects in busy commercial shipping lanes and ports.
