Deep-water Coral Reefs

Acoustic recognition and geological setting
Cold water coral reefs, notably the stone coral Lophelia pertusa, have been found extensively in deep Arctic waters such as the Norwegian Sea. The use of multibeam echosounding, together with advanced visualisation and analysis tools, has been a key to many spectacular discoveries. The world's largest cold water coral reef - the Røst Reef - was mapped in detail in October 2002. Located in the dramatic setting of a large submarine slide, this provides an excellent example of how catastrophic geological processes can create special marine habitats. Another major reef complex - the Sula Reef - demonstrates how mounds select... (read more)

FarSounder On-water Demos

FarSounder will be offering on-water demonstrations to interested parties on 3 April 2014 departing from Jamestown, RI, USA. On board of the R/V Cap'n Bert demonstrations of FarSounder’s 3D, forward looking, real-time navigation sonar will take place to show the sonar's navigational and obstacle avoidance capabilities in deep and shallow water. Engineering staff will be available to discuss both navigation and other applications for these sonar systems. Contact FarSounder to reserve a slot as space is limited. Demonstrations will be held throughout the day, departing at various times. (read more)

Seizing Energy from Water

Best-kept Dutch Secret
At least 10% of the Dutch electricity demand can be met from water, according to the Inspiration Atlas ‘Water as a source of renewable energy’. This is not widely known. In fact, this form of energy generation is one of the best-kept secrets in The Netherlands. The Directorate-General for Public Works and Water Management (Rijkswaterstaat) and Deltares are trying within the Rijkswaterstaat Water Innovation programme to show both government and industry the different options and offer them the opportunities to put their innovative solutions into practice.

Deep-water Industry Event

The "mce Deepwater Development" 2009 technical conference is, for the first time, to be held in Copenhagen (Denmark). It features a packed technical programme and is supported by an exhibition showcasing the world's major companies operating within the deepwater sector.     Hosted by Maersk Oil and organised by Quest Offshore, this year's conference will see Maersk Oil's CEO, Thomas Thune Anderson, welcoming the international delegates and presenting the conference's keynote speech.   According to Quest Offshore, the current estimate of 2009 Global Deepwater Spend is USD164 billion, the oil price is hovering around USD40/bbl and major discoveries for example,...

GEBCO and Deep Water

Data Assembler, Converter, Interpreter and Disseminator
GEBCO uses deepwater survey data to produce bathymetry maps and grids. Published maps appear complete but are in fact based on very little data. Only a portion of the deep data that could potentially be put to use is contributed to the public domain. All would benefit were more data submitted to data centres. BackgroundWhile the general public thinks that all the seafloor has been mapped and many hydrographers and ocean scientists accept published maps and datasets as faithful representations of the deep-sea floor, in reality only a small percentage of the seafloor has ever been directly measured; estimates range...

Innovation in Coastal Water Monitoring

HCTECH
HCTECH is a technology-based company that started as a spin-off of CIS (Centro de Investigaciones Submarinas SL) in Santiago de Compostela (NW Spain). It was founded to improve the management and to further develop the technical know-how gathered during 10 years of R & D in CIS. The company is dedicated to the designing and manufacturing of water quality monitoring systems and other marine technologies. CIS (Centre for Submarine Investigations), founded in 1987, is an environmental consulting company, specialised in the marine environment. For over a decade, CIS maintained a research, development and innovation department that ­generated techniques to prospect... (read more)

Coastal Monitoring of Water Quality

Autonomous Surveying of Shallow Coastal Waters for Clean Seas and Shorelines
The wave-propelled AutoNaut unmanned surface vessel (USV) completed a short trial off the south-west coast of England to monitor the water quality by a sewage outfall. AutoNaut demonstrated its ability to reliably operate in shallow waters whilst also recording and transmitting data. A suite of sensors aboard the USV worked in conjunction with satellite data from synthetic aperture radar (SAR). Analysis indicated that the seawater close to the outflow was not negatively affected. The combination of technologies is pioneering for the application and the trial highlights the potential of this innovative approach to conduct long-term marine monitoring – including the...

Safe Electricity Use Under Water

Preventing the dangerous hazards which may arise from the use of electricity under water are dealt with in ‘Code of Practice for the Safe Use of Electricity Under Water', a seminal publication from the International Marine Contractors Association (IMCA, UK). The Code covers all types of electrical equipment used by a diver - employed for his benefit, either under his control, or under the control of the diving support team. "The Code deals with vital issues such as the prevention of electric shock, and other concerns, including the degradation of electrical insulating material by heat, which can result in the...

Mapping Liquid Water on Mars

To tie in with NASA’s recent announcement about the discovery of liquid water on Mars, Esri has put together an interactive story map showing the craters and canyons on Mars that reveal evidence of water. Watch animations of the recurring slope lineae (water stains) across four different craters and explore satellite imagery and elevation data for the 'Red Planet'. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during... (read more)

Water Quality Data Buoy Order

AXYS wil supply of two WatchMate data collection buoys to the University of Southern California. The solar and battery powered WatchMate's are each configured with two WETLabs Water Quality Monitors, all-in-one instruments that measure salinity, temperature, dissolved oxygen, chlorophyll and turbidity.   The buoys will provide USC's public health and water quality officials in Southern California with a better picture of water quality along the Pacific Coast. The project is led by Burt Jones, a research associate professor in the USC Marine Environmental Biology program, and it covers much of the shoreline of Los Angeles and Orange counties. Jones' team... (read more)
