Seabed Online

Maps and images of seabed habitat, geology and biological data in the seas around North-West Europe can now be viewed online. This resource has been created by the Joint Nature Conservation Committee, in a five nation project called, The Development of a Framework for Mapping European Seabed Habitats, or MESH. Important to the project was discovering more about the processes that determine the existence of certain habitats in a particular location. These habitats are defined by a combination of unique conditions such as current, depth of water, temperature and the rock structure under the seafloor. Understanding and classifying this...

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 Soil Testing System

Schilling Robotics, and Gregg Drilling and Testing have delivered a new Cone Penetration Testing (CPT) system for deep-water seabed soil testing. Gregg is commencing in-water testing of the system today in Long Beach Harbor (CA, USA). Once harbor testing is complete, the system will then be sent to work offshore in June 2009. Schilling supplied the control system and hydraulics for the Gregg-designed CPT system. The control system consists of electrical and communications components, subsea hydraulics, along with topside hardware, console components, and advanced component monitoring and diagnostic software. Gregg's CPT is performed using a cylindrical penetrometer with... (read more)

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)

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)

Seabed Surveys for EMEC

UK-based subsea services company Fathoms Ltd recently undertook two comprehensive surveys for the European Marine Renewable Energy Test Centre (EMEC) based in Orkney. The results of these surveys have enabled EMEC Ltd to extend its capabilities in the marine renewables sector, generating electricity from devices moored to the seabed. Fathoms has recently expanded its operations to include work for clients such as Dounreay Site Restoration Ltd (to detect and recover radioactive particles from the seabed) and the Channel Coastal Observatory (National Oceanographic Centre, Southampton) collecting data to be used in a new coastal model being built to assist with...
