Hydrographic Survey

Hydrographic survey covers a broad spectrum of activities using multiple technologies and techniques, s

these are some (but not all) examples:

1. Bathymetric Survey.

2. Wave and Tidal surveys.

3. Underwater photography.

4. Seabed sampling and core sampling.

Essentially, it is the harvesting, processing, analysis and visualization of marine geospatial data to provide information and understanding of the marine environment and the influences which shape it. The marine environment is complex, dynamic, and the scene of great competition for resource. Whether you are operating a cruise vessel, or building a small jetty it is essential to have access to the highest quality, and most up to date information possible in order to avoid damaging and costly mistakes. In heavily utilized coastal zones the need for information is even more critical as there tends to be a much denser concentration of usage and influences. Hydrography is not merely automated bathymetric echo sounder data gathering but encompasses a plethora of data gathering techniques and analysis to provide a client with the required information.

The start point is to be clear in defining a requirement to select the most appropriate hydrographic method. Often the prime client will be unaware of the multitude of inter-connected, complex underwater effects involved. If this is the case employing a hydrographic survey company which can provide expert advice prior to a project, as well as meeting the requirements of that project will reduce the risk of unforeseen problems later in the project.
