GTI to Supply Low Frequency Sources to Scripps

GeoSpectrum Technologies (GTI) announces it will supply the Scripps Institution of Oceanography (University of California San Diego) with two “C-BASS” low frequency sources.This new technology will allow researchers to conduct low frequency acoustic experiments more efficiently and less expensively than previously possible, GTI said. A successful field trial at Seneca Lake last December caught the attention of Scripps, resulting in the purchase.The fully coherent C-BASS are tuned to operate at 34 Hz and are capable of continuous operation. The energy efficient sources are physically

in Aberdeen, U.K. The calibration procedures improved the resolution and noise reduction of the sensors utilized.Once installed on the structure, the system ran autonomously, and was controlled remotely via radio frequency communications, an acoustic data link and a remotely operated underwater vehicle (ROV) electrical hot stab, removing the need for direct ROV or diver intervention. Ashtead utilized a range of measurement sensors and positioning tools to enhance the accuracy of the data collected, ensuring maximum performance of the system.This approach to subsea system installation was developed

operations. Can you explain why this was chosen as a focus?In developing this prize, one of the market failures that was identified was the expense of mapping the sea floor because of the need for manned ships at sea. By focusing on autonomous operations, we incentivize the development of a range of new vehicles and approaches that can be deployed from the shore and map an area without any humans at sea.The finalists were announced in March; what were the key criteria used to select the teams that would proceed?The team solutions were assessed on their performance against 11 criteria: autonomy, collision

UFRJ Nautilus: A Brazilian AUV Project

The UFRJ Nautilus AUV is an academic project designed to develop autonomous underwater vehicle (AUV) technology in Brazil and participate in the annual Robosub competition. According to project founder, Lucas Armand, a Naval and Ocean Engineering graduate from the Federal University of Rio de Janeiro (UFRJ), the emergence of Nautilus has a lot to do with personal history: “I was having a difficult time in college, because I no longer identified myself with the course. The UFRJ Naval Engineering degree tends to be quite traditional – sometimes even old-fashioned – and I’ve

to operate in mixed environments is unique, whereas the SZC allows access to areas that surface craft, swimmers or human based techniques could not. The Sea Otter SZC operates with negative buoyancy while operating in the lower energy boundary layer. The low profile further minimizes current drag. The vehicle has operated in 1.5-m plunging surf and can cross soft terrain that will not support human loads. Recent tests demonstrated the ability to carry 40-kg payloads as well as tow a 45-kg sled across various marine surfaces.Specs of the Otter-SZC include:Symmetrical dual-sided operation for operation
