High-Resolution 3D Geotechnical Survey Tool

Prior to driving piles into the sub-seabed to serve as foundations for wind turbines, it is critical to ensure that the chosen locations are free from boulders and geohazards. At a wind farm site on the Baltic Sea, previous site investigations and tunnel excavation historica... (read more)

Surveying for Offshore Wind

Many giants are drilling for oil and gas: the gold of the sea. Since the beginning of the new millennium, however, a new kind of energy potential of the sea has been discovered: wind energy. The fastest way to create substantial amounts of this green energy is to build offsh... (read more)

Surveying the Thames Tunnel Route

Following the suspension of Parliament in the summer of 1858 due to the ‘Great Stink’, an act was passed to allow construction of a network of giant sewers, pumping stations and treatment works beneath London. The system was designed by Sir Joseph Bazalgette and... (read more)

Mapping Diamondiferous Gravel

An Aquares resistivity survey was carried out in a river in sub-Saharan Africa to map the sub-bottom features of a diamond concession. Diamondiferous gravels were distinguished remotely from bedrock and other soft sediments by the Aquares Resistivity System (ARS), a sub-bott... (read more)

Amplified Sediment Waves in the Irish Sea (AmSedIS)

Large sediment waves are striking yet poorly understood seabed features in many shelf seas. Very large sediment waves (3–18m in height) have been documented to migrate up to 70m per year in the Irish Sea and some sand waves reach heights of up to 36m (Figure 1). Such t... (read more)

iXblue’s Sub-bottom Profiler Solution

The need for lake & river surveys constantly increases as human activity expands in these areas. While navigation remains a main focus, nowadays other applications such as hydraulic construction inspection, biomass and resource control, pollution tracking or historical s... (read more)

“How to Sustainably Use and Protect Oceans and Coasts”

During the recent Offshore Technology Conference in Houston, Texas, USA, the Executive Order on Implementing an America-First Offshore Energy Strategy was signed to support offshore science development. In the context of the highly dynamic offshore energy sector, 'Hydro Inte... (read more)

Autonomous Arctic Drifting Seismic Buoys

Less than 30,000km of seismic profile exist for the Arctic Ocean. Components of a new autonomous drifting seismic buoy have now been successfully tested using the hovercraftR/H Sabvabaa. Three buoys will be deployed in Spring 2009 and could potentially produce over 5,000km o... (read more)

The Discovery of Long-Distance Sound Transmission in the Ocean

The existence of the SOFAR Channel has been known for many years. In the American geophysicist Maurice Ewing’s authorised biographical memoir The Floor of the Sea, the following passage occurs: “The first time Ewing’s seismic gear was tried at a thousand fa... (read more)

Tsunami Local Alarm System

Tsunamis are in no way a new phenomenon, but the December 2004 tsunami drew attention to warning systems and generated new ideas for those capable of providing timely warning, even when a tsunami is generated near the coast. This article describes such a system, currently at... (read more)

Offshore Surface ­Geochemical Survey (OSGS)
