Argentina established the Naval Hydrography Service on 25 January 1879 to improve maritime navigation. The service mapped coastlines, measured depths, and documented sea conditions. Its work supported shipping routes and naval operations. Detailed charts created by the agency became essential for safe travel in Argentine waters. The service also collaborated with scientific institutions to study tides and marine geology. Over time, it developed into a central authority for nautical cartography. Its founding marked a major advance in maritime science.
