Hydrographic and Geophysical Survey

The Hydrographic and Geophysical Survey line positions TideWise at the forefront of characterizing marine environments in a 100% uncrewed manner. Operating with the first autonomous robots authorized by the Directorate of Ports and Coasts (DPC / Brazilian Navy) and the Hydrographic Center of the Navy (CHM / Brazilian Navy), we conduct surveys according to international standards (S-44 / NORMAM-501) and with a history of Category A and B bathymetry. We operate equipment from various manufacturers, with experience in integrating models manufactured by Kongsberg, Sonardyne, Nortek, Norbit, EdgeTech, Innomar, among others. TideWise's agnostic philosophy allows the integration of such sensors into proprietary robotic vehicles, performing surveys focused on mapping the seabed, subsea, and navigational hazards. Technology optimizes productivity and reduces costs in port surveys of access channels, berths, spoil heaps, and pre/post-dredging bathymetry, generating detailed XYZ clouds and GIS maps.

Our main services include:

• Surveys using a multibeam echo sounder (Multibeam Echosounder MBES);

• Surveys using a single-beam echo sounder (Singlebeam Echosounder SBES);

• Side Scan Sonar (SSS) surveys;

• Sub-bottom profiling for shallow seismic data (using Sub-Bottom Profilers - SBP);

• Current lifting with ADCP;

• Tide gauge surveys;

• Surveys with CTD (Conductivity, Temperature and Depth).
