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)

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...

Additional Excavator Monitoring Systems

The two installations are delivered in addition to the four systems already supplied to Martens en Van Oord, specialising in earthworks, both on land and under water. Both excavators are equipped with rotatable clamshells which are mounted on an extended stick. The inclination of the extendable stick and rotation are both measured and visualised real-time in combination with the standard boom/stick visualisation.   The excavators are mainly used for land dredging applications. As the excavators are equipped as stand-alone system they can also be placed on a pontoon for dredging on rivers and in harbors. The installation was performed by... (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)

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...

Towed Coastal Monitoring Package

The MiniBAT Towed Coastal Monitoring Package (TCMP) is developed to addresses all coastal monitoring requirements in one easy to use system. The TCMP is based on the MiniBAT tow-body from OSIL and is fitted with YSI’s 6600 Multiparameter Sonde (CTD, DO, pH, Chlorophyll, Turbidity). Supplied fully integrated, complete with winch, cable terminations & GPS system etc., allowing rapid coastal surveys to be undertaken from small inshore work boats. The TCMP is designed for use by Harbour Authorities, Environment Agencies, Universities, Survey companies in line with the Water Framework Directive. (read more)

ASL Monitoring for Vancouver

ASL Environmental Sciences has formally handed over to the Port of Vancouver a real-time monitoring system for currents and water levels at the Second Narrows Bridge in the harbour. This project has been in collaboration between the Canadian Hydrographic Service, Vancouver Port Authority, CN Rail and Sultran Ltd, with ASL acting as prime contractor to provide the instruments and system integration. This system, using proprietary Acoustic Scintillation Flow Meter (ASFM) technology along with other off-the-shelf components has completed an extensive, two-year long field trial to confirm its operational reliability. The ASFM technology was selected because it has no moving parts... (read more)

Cost-Effective Monitoring Platform

OSIL will be launching their new range of robust and adaptable Data Buoys at Oceanology International 2008. They will be exhibiting the small and cost-effective OSIL200 buoy on their stand, which illustrates the compact and light-weight design of the buoys.   OSIL's Data Buoys provide a monitoring platform for a wide assortment of instrumentation and their highly stable design makes them suitable for a variety of short and long term applications including ocean, river, coastal and dredge monitoring. They are designed to be completely adaptable to any applications' needs, and can withstand the harshest of conditions thanks to their robust... (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)
