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...

Vessel Corrosion Monitoring

MICAD Marine has begun to include Vessel Corrosion Monitoring as standard equipment in all of its Marine Systems. Corrosion is one of the greatest enemies of all vessels and there are several protective measures that vessel owners can take to eliminate this risk. The typical solution is the placement of zinc on various parts of metallic objects making up submersed parts of the vessels. This new monitoring device offers display and archive of the current status of cathode protection, as well as a permanent log of the entire protective system employed on the boat, for its entire history. If zinc... (read more)

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)

Typhoon Monitoring Instrumentation

Following an international competition, NTU has selected Axys' Triaxys directional wave sensor to measure the waves generated by typhoons approaching the coast of Taiwan. The Triaxys sensor will be integrated onto NTU's modified Atlas (Autonomous Temperature Line Acquisition System) metocean buoy.     Atlas is a 2.3m diameter toroid fabricated with fiberglass over a foam core.  Axys' proprietary Triaxys wave sensor will deliver the highly accurate directional wave data required for scientific research and weather forecasting.   Axys' exclusive representative in Taiwan, Sino Instruments Co. Ltd. facilitated the purchase and will also assist NTU with the integration of the sensor. ... (read more)

Monitoring Deep-Sea Industry

Writing in the scientific journal Nature, scientists have called for increased discussion of independent monitoring of deep-sea hydrocarbon industry activity with the aim of obtaining a better understanding of its ecological impact. The hydrocarbon industry is increasingly searching for hydrocarbon resources at much greater depths and developing drilling technology to exploit them. However, drilling the seafloor at great depths is technically very challenging and carries with it poorly known risks.     “The Deepwater Horizon disaster in the Gulf of Mexico last year and the subsequent discovery of unexpected hydrocarbon accumulation at mid-water depths underscores the need for independent monitoring...

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)
