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)

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...

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)

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 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...

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)

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)

Environmental Monitoring Buoy

UK-based OSIL recently launched its new 1.2m Tern buoy. The platform is designed for extended deployment in harsh coastal environments in deeper water depths, and is suitable for all applications, including scientific studies, water quality monitoring, coastal engineering projects, harbour and coastal monitoring, and maritime traffic control.                                            The system is robust, with all instrumentation and cables held internally, protected by the rugged enclosed top section, which has been designed to minimise damage from the elements or interference. All sensors... (read more)

Long-term Environmental Monitoring

The Marine Institute in Ireland has ordered two YSI 6600 EDS environmental probes from OSIL. The EDS (extended deployment sonde) was carefully selected for its ability to measure environmental parameters over a long deployment period. The YSI probes will be used for monitoring work in the vicinity of aquaculture production sites such as salmon farms and mussel lines to learn more about harmful algal bloom in Irish coastal waters. Each YSI 6600 EDS will be measuring fifteen parameters that include turbidity, chlorophyll, rhodamine, dissolved oxygen, and pH. The YSI data will then be used for research purposes on the Biological... (read more)
