Two of Sonardyne?s long-life sub- sea sensor logging nodes, called Fetch, have been deployed onto the sea oor, from where they will make regular sub- sea measurements using their onboard suite of environmental sensors. When requested to do so, the stored data will be transmitted wirelessly up to the Wave Glider for onward transmission via a satellite link to the shore for near- realtime assessment. This project dem- onstrates how the combination of Fetch and Wave Glider technologies can ex- pand the spatial and temporal resolution of the installed Ocean Observing Sys-tem. After the initial deployment in the Gulf of Maine is completed, the Wave Glider will transit to waters off the mid- Atlantic for additional missions, includ-ing tsunami McCarthy Joins Seabed Technologies Seabed Technologies said that Kevin McCarthy, former VP at Hydroid, has joined as COO. The company also an- nounced that Seabed Technologies has moved into a new manufacturing facil- ity in the Falmouth Technology Park, in close proximity to the Woods Hole Oceanographic Institution. Seabed Tech- nologies was founded to commercialize the technologies developed in the labora- tory of Dr Hanumant Singh of WHOI?s Deep Submergence Laboratory. The company has core business interests in imaging in the marine and polar environ- ment. Its core technology includes high dynamic range camera systems, photo-mosaicing and 3D image reconstruction underwater, and the Seabed family of AUVs and towed vehicles. It holds the exclusive license from the WHOI for the manufacture and further development of the Seabed Autonomous Underwater Vehicle, imaging systems, and software packages developed in the laboratory of Dr. Hanumant Singh in WHOI?s Deep Submergence Laboratory. Tritech?s Gemini SeaTec Sonar Gemini SeaTec provides an early warn- ing of the presence of marine mammals in the vicinity of marine current turbine structures. The Gemini SeaTec system has been  eld tested on the Marine Cur- rent Turbine (MCT) SeaGen installation in Strangford Lough, Northern Ireland, overseen and tested by the Sea Mam- mal Research Unit (SMRU) Ltd. The latest version of Gemini SeaTec system includes improved software algorithms for analyzing moving marine life targets according to their size, shape and swim-ming behavior. Targets are categorized using a traf c light system, indicating the probability that a moving target is a ma- rine mammal. ?Possible? (green) targets are the cor- rect size and shape; ?Potential?(amber) denotes upgraded ?Possible? targets that also have a path that suggests the object is not moving with tidal drift. ?Probable? (red) targets are upgraded from ?Poten- tial? when they have a high probability of being a marine mammal. BlueView Debuts BlueViewer 3D Viewer BlueView Technologies updated the operating software for its 2D and 3D so- nar systems. ProViewer 3.6 and ProScan 3.6 include multiple updates to improve processing speed and ease of use. On-line downloads are available at www. and the new software is in- cluded with the appropriate sonar in new shipments. BlueView also introduced its new 3D point cloud viewing soft- ware, BlueViewer to view the output of BlueView BV5000 3D Multibeam Scan- ners and MicroBathymetric systems. Multi-Function Navigation System Approved The Marinestar Maneuver- ing System (Marinestar MS) designed by Fugro in Norway has been approved by the BSH marine test house in Germany as both a Speed and Distance Measuring Equipment (SDME) and Transmitting Heading De- vice (THD). This means that Marinestar MS can be installed as an alternative to a doppler speed log in order to meet the requirements of SOLAS for ships over 50,000 gt to have the ability to measure speed over the ground in both the forward and athwartships direction. The system can equally act as an alternative to one of the gyro compasses. The system is based upon high performance dual system (GPS & GLONASS) differential po- sition receivers and the Fugro navigation satellite augmenta- tion broadcast. Marinestar MS also acts as a berthing system providing quay distance and approach speed fore and Marine Technology Reporter 57MTR #5 (50-64).indd 57MTR #5 (50-64).indd 575/31/2012 1:22:24 PM5/31/2012 1:22:24 PM
