Managing and Monitoring Dynamic Environments

TCarta Marine has made dynamic environments easier to monitor and manage with the introduction of its multi-scale Shoreline products. Offered in GIS-ready vector format, the Shoreline datasets are derived from satellite imagery and accurately delineate mean sea level for the land-water interface in coastal areas around the world. TCarta Marine is creating the Vector Shoreline Products at global, national and local scales for mapping applications like environmental protection, coastal infrastructure development and flood insurance rate calculations. Many of the Vector Shoreline Products are available off-the-shelf, while others are custom derived from archived or newly collected satellite imagery. Global and Regional... (read more)

Autonomous Seabed Monitoring System Deployed

A long-life acoustic monitoring system developed by Sonardyne International Ltd, UK, to detect minute changes in the seafloor due to settlement has been successfully deployed in Southeast Asia for Brunei Shell Petroleum (BSP). Installed in 45 metres of water, the network of Autonomous Monitoring Transponders (AMTs) that make up the system were supplied with compact subsea instrument housings and anti-trawl seabed frames that have been custom-designed by Sonardyne to provide protection from commercial fishing activities in the area. Structure, pipeline and seabed settlement monitoring is regularly undertaken in life of field surveys. The challenge for operators is to acquire the... (read more)

Radar-based Nearshore Hydrographic Monitoring

Filling in The White Ribbon
Shore-based marine radar techniques have recently proved to be an excellent tool for monitoring erosion and accretion in the dynamic nearshore area through repeated and automated large-area surveys. The ability to routinely survey intertidal areas has always been logistically challenging and expensive due to the limitations imposed by the tides, weather and access. Advances in remote sensing techniques and the development of new data-processing algorithms have made the surveying of these areas much more cost-effective. There is a global need for greater awareness of the sedimentary dynamics of intertidal regions. These seldom surveyed areas are host to a variety of... (read more)

Partnership for Hydrocarbon Monitoring Sensors

Chelsea is to begin working with Liquid Robotics as its technology partner for hydrocarbon sensors. The company has already been working with Liquid Robotics for two years, providing a number of UV AquaTracka Hydrocarbon Sensors for integration into its Wave Gliders. The UV AquaTracka has long been the industry standard for hydrocarbon detection, a reputation proven during the Macondo Oil Spill in the Gulf of Mexico. Originally developed for military applications, the UV AquaTracka remains unique in its ability to detect very low levels of crude and refined oils in the marine and freshwater environment. The UV AquaTracka is so... (read more)

Marine Noise Monitoring Survey Completed

Without mitigation, the installation of driven piles in the marine environment, along quaysides for instance or during installation of offshore foundations, is likely to produce noise levels capable of causing injury and disturbance to marine animals. The UK-based firm Partrac was contracted recently by TSL Contractors to provide marine monitoring services which included acoustic (marine noise) data acquisition prior to, and during, piling works for the construction of Fishnish Pier, Sound of Mull, Scotland. Such effects, although incidental to consented activities, have the potential to conflict with a range of legislative provisions. Although guidance is available to developers on how... (read more)

Real-time Marine Monitoring Systems

Forecasting ocean and regional sea-state
The seas are being monitored, from satellite observations of the ocean surface to the growing number of in-situ measurement networks. The amount of information being generated is huge and should ideally provide a consistent 3D picture of ocean-state, including temperature fields and current structures. Indeed, this is the expectation of a wide range of organisations and individuals engaged in coastal and offshore activities, who would prefer such forecasts to be in the shape of a synoptic overview of present conditions augmented by prediction of two or three weeks. In order to merge all past information and produce a forecast, models... (read more)

Monitoring Dover Tides and Weather

A tide and weather monitoring system which will further enhance the efficiency of shipping movements into the Port of Dover, UK - one of the world's busiest harbours - has been provided by Seatronics Ltd, UK. The new system has UHF telemetry link integrating it with Dover Harbour's LAN to ensure that up-to-date tide and weather information is available throughout the harbour. The applications are many. Valeport Ltd, UK, worked with Seatronics and the Marine Operations and IT Departments of Dover Harbour Board to design, manufacture and install the tide and weather monitoring system. (read more)

Innovation in Coastal Water Monitoring

HCTECH
HCTECH is a technology-based company that started as a spin-off of CIS (Centro de Investigaciones Submarinas SL) in Santiago de Compostela (NW Spain). It was founded to improve the management and to further develop the technical know-how gathered during 10 years of R & D in CIS. The company is dedicated to the designing and manufacturing of water quality monitoring systems and other marine technologies. CIS (Centre for Submarine Investigations), founded in 1987, is an environmental consulting company, specialised in the marine environment. For over a decade, CIS maintained a research, development and innovation department that ­generated techniques to prospect... (read more)

Wreck Monitoring in Dredging Operations

Multiple survey and positioning techniques for MV <i>Assi Eurolink</i>
The problems posed by the wrecked vessel Assi Eurolink called for unique solutions that have set a new benchmark in the way that similar wrecks are made safe. On 25th January 2003 a collision occurred between the Swedish vessel Seawheel Rhine and a Dutch freighter, the Assi Eurolink. The collision was within the shipping lane ‘Friesland Junction’, about 77 kilometres (48 miles) off the coast of the Dutch island of Terschelling. The Swedish ship Seawheel Rhine sustained visual damage to her bow above water line, but the ship was able to continue to Hamburg. However, the Assi Eurolink sank almost... (read more)
