2. Geophysical survey - Wikipedia

   en.wikipedia.org/wiki/Geophysical_survey

   Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.

3. Near-surface geophysics - Wikipedia

   en.wikipedia.org/wiki/Near-surface_geophysics

   Magnetic surveying can be done on a planetary scale (for example, the survey of Mars by the Mars Global Surveyor) or on a scale of meters. In the near-surface, it is used to map geological boundaries and faults, find certain ores , buried igneous dykes, [ 8 ] locating buried pipes and old mine workings, and detecting some kinds of land mines .

4. Offshore geotechnical engineering - Wikipedia

   en.wikipedia.org/wiki/Offshore_geotechnical...

   Geophysical surveys are conducted from a research vessel equipped with sonar devices and related equipment, such as single-beam and multibeam echosounders, side-scan sonars, ‘towfish’ and remotely operated vehicles (ROVs). [20] [21] For the sub-bottom stratigraphy, the tools used include boomers, sparkers, pingers and chirp. [22]

6. Aeromagnetic survey - Wikipedia

   en.wikipedia.org/wiki/Aeromagnetic_survey

   An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance.

7. Viridien - Wikipedia

   Minerals and mining: Viridien supports mineral exploration through global geological predictions and plate kinematic studies, satellite-derived surface material alteration targeting, provision of geophysical equipment, and the development and provision of modeling software, as well as monitoring services for mining operations and mine tailing ...

8. Survey vessel - Wikipedia

   en.wikipedia.org/wiki/Survey_vessel

   A survey vessel is any type of ship or boat that is used for underwater surveys, usually to collect data for mapping or planning underwater construction or mineral extraction. It is a type of research vessel , and may be designed for the purpose, modified for the purpose or temporarily put into the service as a vessel of opportunity , and may ...

9. Underwater survey - Wikipedia

   en.wikipedia.org/wiki/Underwater_survey

   Underwater geological surveying employs techniques from the underwater equivalent of a traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as boreholes, to the use of geophysical techniques and remote sensing methods. An underwater geological survey map typically superimposes the surveyed extent and ...
