Offshore marine infrastructure projects often require specialist geophysical & bathymetric survey company to safely plan and execute construction. Projects including offshore wind farm development, MRE (marine renewables) development, cable and pipeline route investigation and coastal and civil engineering all require a thorough understanding of the immediate marine environment. Geophysical survey Australia using a multitude of sensors are undertaken to measure and characterize the site of each marine project. Contact iXblue Australia the geophysical & bathymetric survey company for more details.
High Resolution Bathymetry
Multi-beam echo sounders are used to obtain high resolution bathymetry of the seafloor. Full sea floor overage surveys using this technology provide vital and detailed information on the nature and character of the survey site.
Sonar survey is the provision of seabed imagery for seabed nature characterization as well as obstruction detection and identification. We use side scan sonars, back-scattered multi-beam data and synthetic aperture sonars to capture and record this imagery.
Marine Magnetometer Survey
Magnetometry information aids in the detection of geomorphological anomalies and ferrous obstructions (unexploded ordnance, ship wrecks, cars, containers, cables and pipelines).
Sub-Bottom Profiling / Seismic Survey
We have experience in providing information on sediment layers and sub-bottom geological morphology. Our experience includes the use of shallow and deep sub-bottom profilers (chirp, boomer and sparker) and ultra-high resolution seismic (sparker and Air-Gun) (UHRS) for pre-construction engineering.
We regularly team with ROV service providers to support the deep deployment of geophysical equipment to obtain high resolution survey – regardless of the water depth. ROVs are typically employed for cable and pipeline route surveys.
Data Management and GIS
The International Association of Oil and Gas Producers (OGP) industry has mandated the use of standardized guidelines for the capture and reporting of GIS data. iXblue owns and operates industry Esri ArcGIS software for this purpose and delivers client oriented GIS structure following the OGP guidelines as a baseline.
When it comes to land surveying, a geophysical survey is used to identify resources without disturbing or sampling surfaces. This is a ground-based physical sensing technique that detects geological and other substances below the surface, and facilitates the production of a map or detailed image of a particular area. A geophysical survey is essential for surveying any areas that are culturally sensitive, like a cemetery, and is also used for mineral exploration and by archeologists.
A marine geophysical survey does the same below water in order to understand the seafloor and sub-seafloor geology. We use a variety of sensors to measure the shape and density of the seafloor and to define and map sub-seafloor structures. We use sonar equipment to provide bathymetric and backscatter mosaics, and to make high spatial resolution maps. LIke land geophysical surveys, marine geophysical surveys can be undertaken without disturbing or sampling the seafloor and are often used in fragile and protected environments.
A bathymetric survey allows us to measure water depths, and to map any underwater features. This data is used to create nautical charts for navigational safety, and is also valued by scientists for understanding how climate change and extreme weather events impact bodies of water and the marine ecosystems.
