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

NOC Predicts Increase in Extreme Sea Levels

A new study has predicted that future global warming will lead to an increase in ‘extreme sea levels’, with consequent flood risks to coastal infrastructure and human populations. Extreme sea levels occur through a combination of high tides and extreme weather events, which can generate storm surges and high wind waves. These incidents are intensified by gradual rises in mean sea level and predicted increases in tropical cyclone activity. Researchers have taken all these factors into account to assess future risks of extreme sea levels up until the year 2100. The National Oceanography

; Sound waves propagate through the water column so echoes are returned and processed from many depths. The vertical range of this collection of measurements - called a profile of ocean current velocities - is greater for lower frequency sound waves.   Introduction Thanks to a spirited cadre of marine scientists and engineers, high-tech ocean observatories are now operational. These sites provide a continuous presence in the ocean for sustained and interactive observing. Many combine innovative infrastructure with multi-discipline marine sensors.   Installed at various depths, these observatorie

US Navy Submarines Surface in the Arctic Circle

 A pair of U.S. Navy submarines recently surfaced in the Arctic Circle as part of multinational maritime exercise north of Alaska.   Los Angeles-class fast attack submarine USS Hartford (SSN 768) and Seawolf-class fast attack submarine, USS Connecticut (SSN 22) surfaced in the Arctic Circle March 10 during the multinational maritime Ice Exercise (ICEX) 2018.   Both submarines, as well the UK Royal Navy submarine HMS Trenchant (S91), are participating in the biennial exercise in the Arctic to train and validate the warfighting capabilities of submarines in extreme cold-water conditions

Digital Ocean: Making Subsea Data More Easily Accessible

The digital ocean is a reality and U.K.-based digital communications marine technology firm Sonardyne International Ltd is one of the organizations driving innovation to enable the extension of electronic and communications connectivity into the subsea domain. Based on a presentation given by Tom Rooney, Lead Trainer at Sonardyne, at the Digital Ocean conference held in Galway, Ireland in June 2017, this article describes the current state of play in the subsea acoustics and optical communications technology field, presents examples of the many ways these technologies are being applied and considers

An Industry in Change

press releases announcing the launch of new, innovative products. ‘First time ever’ is an almost daily term I encounter within my inbox. There have been hundreds of companies starting up recently in the unmanned space over the last decade, and Hook believes we will continue to see more in the marine sector in the decade to come.    Hook said, “There will be a healthy amount of these innovative ideas that are either ahead of their time or got surpassed by something else, so they will drop off. But there is certainly room for more innovation to enter the industry yet. At the
