Oceans of Earthquakes

Globally, the proliferation of sensors and resultant explosion of data is growing at exponential rates. Every digital device and sensor is expected to be available day/night to provide instantaneous results. This is possible if sensors are land or space based. This is not th... (read more)

Relationship between Gas-bearing Sediments and Biogenic Mounds

Here we present the winning project of an industry-supported student research campaign, initiated in 2013 by Innomar Technologie GmbH, Germany. More than 25 European scientific institutions participated with research proposals from Master and PhD students in order to perform... (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)

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)

Flexible High-resolution Seismic Method

Traditionally, the upper part of the shallow seabed is investigated using low frequency echo sounders to enable safe navigation, and even lower frequency profilers for seabed structure mapping. However, the results of these systems often lack accuracy and, as a consequence,... (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)

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)

“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)

Offshore Surface ­Geochemical Survey (OSGS)

The all-Russian Scientific Research Institute for Geology & Mineral Resources of the Ocean (VNIIOkeangeologia) is situated in St. Petersburg, Russia and is currently the leading scientific organisation of the Russian Federation Ministry for Natural Resources in the field... (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)
