Product Description

Deep Earth Metal Detector underwater magnetometer metal detector marine magnetics survey

What is underwater magnetometer?

A underwater magnetometer is a device that detects and measures magnetic fields. It is commonly used in ocean exploration to survey and map the seafloor, as well as to locate and investigate shipwrecks and other cultural heritage sites that may be hidden beneath the water's surface. The magnetometer works by detecting small variations in the Earth's magnetic field caused by the presence of magnetic materials, such as iron or steel, in the surrounding environment. By analyzing these variations, researchers can create detailed maps of the seafloor and locate and study underwater cultural and geological features.


How to do Marine magnetometers?
The process of using a marine magnetometer usually includes the following steps:

1.Installation: Mount the marine magnetometer on a ship, submersible, or other marine platform. During installation, ensure that the equipment is firmly fixed and placed horizontally.
Calibration: Calibrate the marine magnetometer using a standard magnetic field source to ensure the accuracy of the measurement results.

2.Data acquisition: Move the marine magnetometer in the ocean to collect data on the strength and direction of the Earth's magnetic field. During data acquisition, maintain equipment stability and avoid external interference.

3.Data processing: Process the collected data, including removing noise, correcting offsets, and other steps, to obtain data that can be used to draw a map of the seabed magnetic anomaly.

4.Plotting and analysis: Based on the processed data, draw a map of the seabed magnetic anomaly and analyze and interpret it to infer the source of the magnetic anomaly and its possible geological significance
