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)

Towards Monitoring Dumped Munition Threats

NATO SPS Project MODUM
MODUM project is financed by the NATO Science for Peace and Security programme. It unites 8 Institutions from Poland, Russia, Canada, Germany, Lithuania, Estonia, Sweden, Denmark and Finland. The goal of the project is the development of cost-effective and accurate methods for surveying, identifying and onboard analysis of dumped chemical munitions. Dumped Chemical Weapons pose an actual environmental and security hazard in the Baltic Sea Region. Their actual positions are unknown, and pollution originating from corroded munitions can only be roughly estimated. Nowadays, with more and more Industrial Activities being performed in the Baltic Sea Area, the threat level is... (read more)

Coastal Monitoring of Water Quality

Autonomous Surveying of Shallow Coastal Waters for Clean Seas and Shorelines
The wave-propelled AutoNaut unmanned surface vessel (USV) completed a short trial off the south-west coast of England to monitor the water quality by a sewage outfall. AutoNaut demonstrated its ability to reliably operate in shallow waters whilst also recording and transmitting data. A suite of sensors aboard the USV worked in conjunction with satellite data from synthetic aperture radar (SAR). Analysis indicated that the seawater close to the outflow was not negatively affected. The combination of technologies is pioneering for the application and the trial highlights the potential of this innovative approach to conduct long-term marine monitoring – including the...

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)

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)

Satellite-based Water Quality Monitoring

EOMAP, Germany, has launched a high-resolution monitoring service for inland and coastal waters, with water quality information directly accessible online through the eoApp web application. Monitoring water quality for inland and coastal waters is a requirement for many government and private sector entities, which includes identifying long-term trends and understanding emerging problems over large areas that contain numerous water bodies – all to be done in near real time. The service is supported by data from a fleet of satellite sensors and uses proprietary physics-based processing technologies. The base product suite includes water quality parameters such as turbidity, chlorophyll concentrations... (read more)

Benefits of UAS Breakwater Monitoring

The North Sea Canal in The Netherlands connects the Port of Amsterdam with the sea. The two breakwaters at the mouth of the harbour in IJmuiden are usually monitored on displacement of basalt block by airborne Lidar and on subsidence by annual levelling of permanent points. Could a camera-equipped UAS survey conducted simultaneously with a bathymetric survey provide information of equivalent accuracy? A recent study has shown that it could: time series of 3D models of the breakwaters are useful for erosion and subsidence monitoring. By Pieter Franken, Skeye BV, The Netherlands Monitoring of the breakwaters at IJmuiden, The Netherlands,... (read more)

Underwater Positioning and Autonomous Monitoring

Sonardyne International, UK, will be attending its first Sea Tech Week exhibition in Brest, France, taking place from 8 to 12 October 2012 at the Congress Centre Le Quartz. Located on Stand 9, Sonardyne will be demonstrating Scout, a portable acoustic positioning system designed for tracking divers, ROV and towfish in waters of up to 1,000 metres deep. The system’s ease of use and high performance has earned Scout an enviable track record on a wide range of global projects. Sonardyne will also be showcasing its range of autonomous monitoring technologies and acoustic release transponders. Designed for low-cost, long endurance... (read more)
