hydrographer
Charts the seas
A hydrographer surveys and maps bodies of water—measuring depths, currents, tides, and shoreline features.
The work supports navigation, coastal engineering, and marine resource management.
The hydrographer charted the harbor's shipping channels.
Most hydrographers work for government agencies or maritime organizations.
