Iceberg Monitoring

A joint experiment between SUE Atomflot and ScanEx Research & Development Centre, Russia, was conducted in September 2011 on the overall detection of icebergs in the Vilkitsky Strait, which is the narrowest and most congested section of the Northern Sea Route between the Taimyr Peninsula and Severnaya Zemlya.   At the preliminary stage of the experiment the Atomflot Staff of Ice Operations reported the coordinates of icebergs, visually detected from board the icebreakers and using on-board radar. Equipped with this information ScanEx RDC conducted overall real-time imaging of the Strait area using radar and optical satellites data.   Information about... (read more)

Monitoring Technologies

Highly advanced monitoring instrumentation will be the theme for YSI's participation at 'Ocean Business 2009' in Southampton (UK. The company will demonstrate two new technologies; the 'EcoMapper' a remote control underwater vehicle for plotting water quality over wide areas and a multiparameter monitoring platform that has been developed as part of two EU funded research projects.   The 'EcoMapper' is a unique remote monitoring system which only requires one person to deploy and retrieve, has integrated water quality sensors, intuitive mission planning software, and weighs less than 21Kg. It is ideal for routine mapping of lakes, reservoirs, rivers, estuaries and... (read more)

LiDAR Monitoring Coastal Erosion

A new bathymetric survey of the Corsican coastline has been commissioned to provide detailed information about ongoing coastal erosion on the Mediterranean island as well as to assess the impact of manmade structures both on future erosion and navigation safety. BRGM in partnership with OEC (Office de l'Environnement de la Corse) and with the contribution of AERMC (Agence de l'Eau Rhône Méditerranée Corse) have appointed BLOM, UK, and its Hawk Eye II scanning device, to undertake an aerial LiDAR survey of the Oriental Coastal Plain of Corsica, providing some 120km² of new data.   Subject to intense meteorological events, including...

Monitoring Sludge Disposal

Dredging is essential to maintain navigation in ports and harbours. Much of the material that is removed during dredging is clean enough to be disposed of in open water depots at sea. According to the protocol defined in the London Convention (1972 and 1996), the impacts of these open water depots on the surrounding environment have to be monitored. Thus far, monitoring of sediment mobility and sediment transport has mainly been carried out by point measurements. These measurements provide only limited information and sometimes require ambiguous extrapolations. With the development of systems that provide high-resolution, quantitative information of morphology and... (read more)

On-Line Environmental Monitoring

GEMS recently completed a five-month environmental compliance monitoring programme in Fos-sur-Mer on the south coast of France. Two surface buoys were deployed to monitor sediment plume dispersal during dredging operations, and offer protection for the commercially sensitive oyster beds in the vicinity. Each buoy was interfaced to a subsea YSI-6600 sonde fitted with turbidity, conductivity, temperature and pressure sensors. Data were relayed to GEMS UK-based ARTEMeS server at ten minute intervals via a GSM modem programmed with GEMS proprietary firmware.   The systems were designed, built and deployed within one week of order using the joint expertise of GEMS Survey...

Monitoring Ice From Space

Starting 20th December 2010, ScanEx Center, Russia, has been carrying out satellite imagery of the process of ice cover formation on the rivers of the north of the European part of Russia and Siberia. During the freezeup period ice hummocking occurs within the limits of ice-hazardous areas, which during the spring flood may result in formation of ice jams and flooding of wide areas of the flood plain and of residential areas and facilities nearby.   Imaging has been conducted using SAR images delivered from RADARSAT-1 and ENVISAT-1 satellites. If needed, radar images of RADARSAT-2, TerraSAR-X and COSMO-SkyMed programs can... (read more)

Acoustic Monitoring Workshop

The Marine Renewable Energy Center would like to invite readers to a workshop on the Status and Applications of Acoustic Mitigation and Monitoring Systems for Marine Mammals. Sponsored by the Minerals Management Service of the US Department of Interior, the three-day workshop will take place on 17–19 November 2009 in Boston, Massachusetts.     The workshop will focus on the capabilities, applicability, feasibility and availability of current acoustic monitoring systems. A thorough examination of available hardware and software, capabilities and limitations of the systems, requirements for operation and use and the current and future applications to offshore industries will allow...

Oceanology Improves Weather Monitoring

An AXYS WatchMate1.8DM buoy has been deployed in the external port of La Coruña, Spain. The WatchMate oceanographic buoy strengthens the weather monitoring programme operated by Puertos del Estado (PdE) in the Galicia region. The buoy system monitors additional strategic environmental parameters over the existing REDCOS TRIAXYS buoys for operation of the port and to improve the local marine weather forecasting models. The WatchMate transmits oceanographic and meteorological data like directional waves, marine currents, salinity, sea surface temperature, wind (speed and direction), atmospheric pressure and temperature. Puertos del Estado can also expand these capabilities to add more sensors including: water... (read more)

Monitoring Marine Pollution

Detecting Offenders by Satellite in the Eastern Black Sea
An increase in marine traffic has recently been registered in the Black Sea, which is often accompanied by illegal oily water dumps, leaks during loading/off-loading operations and a higher risk of accidents. One of the primary tasks of ScanEx Research and Development Center is the operational satellite-based monitoring for real-time detection of oil spills and their sources. Repeat offenders of waste dumping and sources of pollution have been confidently identified, encouraging others to adopt a more responsible attitude towards the marine environment. View Larger Map According to statistics, transportation is the main source of world ocean pollution. This is also... (read more)

Monitoring of Sediment Displacement

During current pipelaying activities in German waters for the North Stream pipeline between Russia and the EU, Aqua Vision BV performed vessel-based tracking of water column characteristics in the vicinity of dredging and pipelaying activities. The measurement programme involved monitoring during two pipelaying phases: dredging and pipelaying. Combining high-resolution data collection (using Acoustic Doppler Current Profilers) and real-time plume detection software (ViSea-PDT) makes it possible to map the size and concentration of sediment plumes. This information is subsequently used to validate predictions based on numerical modelling studies.Sediment monitoring is part of a larger monitoring programme, involving modelling studies and moored...
