What is a bathymetry survey?

Bathymetry is one of the technologies used in coastal mapping. It is also called seabed mapping or depth map. This is a technique used to measure or map the depth of water. It is also used to measure the height of terrain under certain conditions. Bathymetry is also used to measure the depth of snow.

multibeam bathymetric survey has many uses, especially in the marine industry. These include the following:

– For offshore activities, this helps determine the exact location of an oil rig or where a ship has crashed.

– To measure the depths of underwater volcanoes.

– To know the depth of water to aid in sea navigation, determining the speed and direction of currents and the presence of underwater obstacles such as reefs and sunken ships or objects that can threaten divers.

– To monitor and measure changes in the sea level.

– To monitor and measure changes in beach erosion.

The equipment used for the bathymetry survey includes a sonar system, metal detector, video camera, or Multibeam echosounder system.

How does it work?

The Multibeam system sends sound waves to different angles while moving along the seabed. The Multibeam system sends echo sounder signals to different angles while moving along the seabed. Multibeam bathymetry is used in hydrographic surveys. Multibeam echo sounder can measure water depths, bottom topography, and water velocity.

Multibeam systems today have a wide bandwidth that can be used for traditional hydrography and other applications such as seabed classification, imaging and seabed classification, imaging, and mapping.

What is a Multibeam bathymetry survey?

A multibeam bathymetry survey is used to determine the seabed depth and its properties. Multibeam bathymetry is one of the most popular technology for seabed mapping. Multibeam bathymetry survey provides detailed information about the ocean floor. In addition, it determines whether the seabed is suitable for building structures or laying pipelines.

Multibeam bathymetry has many other uses. These include the following:

– To find out if an area is suitable for dredging or not.

– To determine where to place and build an offshore structure such as a wind farm and determine the best place for building a port.

– It helps determine areas that are safe to navigate.

– It is used for seabed classification, imaging, and increased quality of seafloor maps.

– It helps to know the location of underwater obstacles.

– It is helpful to find out how much silt, sand, and rocks are present on the ocean floor.

– It can be very useful in exploring oil and gas, providing information on the earth’s geology.

– Multibeam bathymetry helps in the study of coral reefs and other marine habitats.

– It helps to know how close you are to a hazard.


A bathymetry survey is an essential part of coastal mapping. This helps in understanding the sea area where it is being done. In addition, it provides more information about the seabed.

The multibeam bathymetry survey data is used to understand the coastal processes, sediment dynamics, and marine habitats such as underwater vegetation and coral reefs.
