Mapping Northwest UK Seabed

The Maritime and Coastguard Agency (MCA, UK) and six partner organisations launched the Ireland, Northern Ireland and Scotland Hydrographic Survey (INIS Hydro) project at the Belfast Harbour Commissioners Office on Monday 4th July 2011. INIS Hydro, which receives GBP3.2 million from the European Union's INTERREG IVA Programme, will produce a standardised hydrographic survey specification and accurate high-resolution bathymetric datasets for seven important seabed areas to the east of Ireland/Northern Ireland and off the west coast of Scotland. A total of 1400 km2 will be surveyed by the partner organisation's research vessels fitted with multibeam sonar technology.   High-quality bathymetric information... (read more)

Klaipeda Harbour Seabed Mapped

The Lithuanian Coastal Research and Planning Institute (CORPI) has recently completed the first ever 100% coverage survey of Klaipeda Harbour, Lithuania, using the Kongsberg GeoAcoustics GeoSwath Plus COMPACT system. This EU-funded project was carried out during the implementation of the Sustainable Management of Contaminated Sediments (SMOCS) project, developed under the framework of the Baltic Sea Region Programme 2007-2013. The work focuses on the mapping of contaminated sediments in the modern port development area. Full-scale, shallow water multibeam, sidescan sea floor imagery and seismic mapping were carried out by CORPI's staff in order to gain a full understanding of the morphology... (read more)

Seabed Classification Capability

Chesapeake Technology has added seabed classification to SonarWiz 5. The new functionality offers a fast and easy way to classify sea floor sediment, such as gravel and sand, for use in a wide range of sonar mapping missions including habitat studies, dredging projects, pipe and cable laying projects, and at-sea platform construction. For the military, for example, it is extremely important to know the bottom types that will allow mines or underwater improvised explosive devices (IEDs) to be buried easily and therefore hidden from side-scanning sonar. The classification map will enable military planners to select a route that avoids areas... (read more)

Acoustic Seabed Classification

Integration into hydrographic survey programmes
Acoustic seabed classification is rapidly gaining acceptance as a useful tool amongst the world's ocean community. Commercial classification products can measure acoustic diversity in the surficial seafloor zone and produce thematic maps of the resulting acoustic classes. Hydrographic services throughout the world routinely conduct bathymetric surveys using single beam sounders and multibeam sonar. These operations are ideal candidates to serve as 'surveys of opportunity' for acquisition of acoustic classification information. The hydrographic office itself gains significantly better seafloor information for charting purposes, with the added benefit that the ocean community outside hydrography gains a new capability to manage the delicate...

Seabed Resources and Hydrography

Exploration of seabed resources using bathymetry and geology
The seabed of the Dutch sector of the North Sea is one of most densely sampled marine areas in the world. Sampling started in the mid-1960s with the exploration of fill sand in the coastal zone. Since that time, a reconnaissance mapping programme of the entire territory has been carried out in close co-operation with the North Sea Directorate of the Dutch Ministry of Public Works and Water Management, and the Hydrographic Office (HO) of the Royal Netherlands Navy. The sample spacing varies much from north to south and from east to west, reflecting the differing relevance of various areas... (read more)

OSI Completes Seabed Characterization Projects

Ocean Specialists Inc (OSI), has announced the completion of a series of seabed characterization projects that involved geophysical and geotechnical surveys at selected locations in the Gulf of Mexico and Western Atlantic. OSI incorporated the survey resources of its sister company, CSA Ocean Sciences Inc (CSAOS), mobilizing a total of three separate missions under rapid planning and mobilization conditions. The Operations involved a 150ft DP-1 class vessel based in the Gulf of Mexico, as well as electronic seabed classification with the 8.5m purpose-built CSA Surveyor in the Atlantic locations.

Solution for Seabed Seismic Acquisition

Five months after CGGVeritas, France, and Saudi Aramco, Saudi Arabia, signed a Memorandum of Understanding (MOU) for collaborative research and the development of geophysical acquisition, processing, analysis and interpretation technologies, the two companies have entered into a collaboration to conduct a major joint R&D project, known as SpiceRack, intended to herald a robotised solution for seabed seismic acquisition. Based on the deployment of self-propelled recording nodes, this solution is expected to lead to a step-change in the efficient delivery of reservoir quality seismic data. Both companies will draw on their seismic acquisition experience and allocate resources to the SpiceRack project.... (read more)

Seabed Mapping and Inspection 2013

The annual Seabed Mapping and Inspection conference took place from 6 to 8 February 2013 in Geilo, Norway. The conference had more than 150 participants, and included people working with technology development, survey and inspection in the marine segment of the oil and gas industry. The conference was held in Geilo, a beautiful winter paradise with 39 downhill slopes and 550km cross country tracks, more or less as far away from the ocean as you can get in Norway. With generous lunch breaks allowing for skiing, or just soaking in the spa, the conference had an informal atmosphere combined with a... (read more)

Seabed Investigations off NW Australia

Fugro has been awarded a combined geophysical and geotechnical project by Hess Exploration Australia Pty Ltd (Hess) to assist in activities in the Northern Carnarvon Basin offshore Northwest Australia. Fugro’s work will comprise seabed and shallow geological investigations, including in areas of difficult terrain. For the first phase of the survey Fugro will utilise one of its Hugin 1000 AUVs to map the seabed. The data will be used to optimise planning for the subsequent sediment sampling phase where a variety of techniques will be used. Fugro’s geoconsultancy team will also deliver an integrated data model for input to Hess’s ongoing... (read more)
