Research Into Underwater Impact of Wave-energy Converter

Wave-energy developer Carnegie Wave Energy has released the results from its environmental monitoring and assessment programme undertaken as part of the recent deployment of its commercial-scale CETO unit (CETO 3) off Garden Island, Western Australia. These results were presented by Carnegie's Site Development Manager, Tim Sawyer, at the Asia Pacific Clean Energy Summit in Honolulu, Hawaii.     Underwater noise monitoring and assessment was carried out by Curtin University's Centre for Marine Science and Technology (CMST). Underwater fauna monitoring was carried out using baited and unbaited video cameras and analysed by environmental specialist RPS Environment, based in Perth, to assess... (read more)

Sidescan Sonar Survey for Nord Stream

MMT (Sweden) has been awarded a contract for sidescan sonar survey and a camera-based study of benthic fauna by Nord Stream. The scope of Nord Stream's monitoring campaign is to assess the impact of the presence of the pipelines on the near-seabed currents through the observation of potential localised scour and sedimentation. To determine seabed sediment features such as objects, linear features, obstructions and sediment characteristics, MMT will use an ROTV-mounted sidescan sonar system. The survey will be performed this summer in Finnish waters followed by a camera-based study of benthic fauna on hard bottom south of the Sandkallan Natura... (read more)

The Norwegian MAREANO Seafloor Mapping Programme

Although the marine resources in Norwegian offshore waters are quite intensively exploited by primarily the petroleum industry and fisheries, the knowledge about seafloor habitats is scarce. Any destructive consequences from e.g. petroleum-related seafloor installations and fishing gears on the benthic environment may therefore in general be challenging to foresee. Factors that might be negatively influenced may include e.g. benthic species diversity, benthic production and bottom substrate. This, and the need for filling the obvious benthic knowledge gaps offshore, was a main driver behind the establishment of the MAREANO programme – Marine Areal Database for Norwegian Waters. The process towards a... (read more)

Exploring the Wold’s Most Unknown and Least Protected Ocean

Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located. Furthermore, researchers are often using advanced instruments that have never before been deployed in the field; if something goes wrong, troubleshooting can be a drawn-out and frustrating process. Lack of Decent Communication Until recently, a major aggravating factor has been the... (read more)

Congo Environmental Survey for Creocean

Creocean has recently successfully completed an Environmental Baseline Survey (EBS) for TOTAL-E&P-Congo on the Moho-Bilondo field. The survey, carried out with scientific support from Thales Geosolutions South Africa and with the technical support of an RV Geoexplorer, provided water quality, sediment and benthic fauna information, at 700 to 900 metre depth. The data collected will describe the environmental sensitivity of the oil field. Creocean scientists use all parameters of the marine environment, including the biological indicators developed specifically for oil and gas areas. (read more)

Post-trawling Seabed Recovery

A voyage to find out what happens to seabed fauna in a deep-water trawling area if you leave it undisturbed several years got underway on 9th May 2011. The RRS James Cook set sail from Glasgow, Scotland (UK) in the direction of Rockall Trough, Rockall Bank and Hatton Basin, .     The deep-water banks and basins to the northwest of the UK are rich habitats for a variety of benthic species, including sponge reefs, cold-water coral mounds and sediment communities. At the same time, those areas form important fishing grounds for an international fishing fleet, including bottom fisheries such... (read more)

Oceans 16 MTS/IEEE Monterey

The program kicks-off with workshops and tutorials then moves on to the core technical program over several days. Join your peers for breakfast, lunch, or dinner at any number of top-level establishments, which are all within a few feet of the hotel and the convention center. Several other special events are also being planned. These include tastes of the food and wine that the Monterey area is famous for. The week will also include in-water demonstrations and exhibits of the latest in ocean technology. On the culminating evening of the conference, find yourself strolling between the local flora and fauna... (read more)

RTsys Listens in on Tidal Turbine

The environment of the Sabella D10 tidal turbine, including underwater sounds, currents, wave, etc., is analysed using a sensor system developed by RTsys (France). Having been tested over the course of a year, between 2015 and 2016, Sabella D10 will be submerged once again in spring 2017 for further testing in the Fromveur Passage, off the coast of Brittany. The system offered by RTsys enables the simple, reliable, remote use of a set of sensors for measurements such as current and wave measurements in addition to underwater video cameras and hydrophones. The objective is to better understand the parameters of... (read more)

Mareano Survey Completed

MMT (Marin Mätteknik, Sweden) was awarded the 2011 Mareano survey contract by the Norwegian Hydrographic Service. The survey commenced in April and was finished in August 2011. It included bathymetric data acquisition and processing in the Nordland VI area of the Norwegian Sea, west of Bodø, Norway.     The area that was surveyed covered roughly 9,000 sq km and varied between approx. 200 and 1,200 metres in depth. The assignment was conducted by the MMT Survey vessel Franklin, length 56 metres, equipped with a Kongsberg EM710 multi-beam echo sounder.   The aim of the Mareano programme is to fill in...

Clear Message during Opening of US Hydro

During the opening keynote speeches of US Hydro in National Harbor, USA, US Senator Sheldon Whitehouse called upon the audience of American hydrographers to combine their voices with those of our oceans. Every day they are signalling the hugely damaging impact of pollution and climate change on the Earth’s seas, its flora and fauna and hence the planet as a whole. At the same time the senator also emphasised the need for federal funding for research and science to recover and undo the influences of climate change. Adding to Senator Whitehouse’s message Robert Ward, president of the International Hydrographic Organization,... (read more)
