The Falmouth Scientific Unveils New Transducers
announced the release of two new transducers covering bands from 200Hz-2000Hz and 2000Hz-20KHz.The AT-650S-AUV TRIOD Low Frequency (200Hz to +2000Hz) Acoustic Projector. The AT-650S-AUV TRIOD single element projector provides a low frequency broadband sound source for applications including underwater communications, sub-bottom profiling or others in a compact form factor for AUV or other underwater applications. An optional Ultra High Definition Audio Class D Amplifier and Troidal Matching Transformer allows for a line level input powered by 48VDC and as low as 24VDC at a reduced power output. The

multi-hop routing, fragmentation and reassembly, contention-free communication, and much more, providing users with a more reliable and efficient way to send data underwater. With a fully functioning network stack out of the box, the S1000-N offers users a powerful and affordable solution for underwater communications, according to Subnero and Popoto.One of the key features of the S1000-N is its ability to operate at a low power draw, while still offering the benefits of a software defined modem. The S1000-N supports multiple computer languages for interfacing (e.g. Java, Python, Groovy, Julia, C, JavaScript)
CSignum Demonstrates Capabilities of Electromagnetic RadiEM Modem at OceanBusiness
CSignum Ltd., a company specializing in cable-free underwater communications and actionable insights for ocean and freshwater industries, on Tuesday publicly demonstrated its new RadiEM Modem at Ocean Business in Southampton. "Available today and successfully deployed in partner trials, RadiEM is the first platform to use low-frequency electromagnetic (EM) fields, nature’s perfect through-the-surface energy to transmit more data wirelessly from more places than is possible with cable, acoustic, and optical," CSignum said.According to CSignum, RadiEM is the only technology that can

, says Sloane. “The benefit of a shoal is that, as each vehicle understands how it’s being effected by the environment, as a group they can figure out the best way to approach the mission.”Photo courtesy ecoSUB RoboticsEvoLogicsWhile EvoLogics’ main products are underwater communications and positioning, the company has also been developing its own vehicles and now also navigation software, so that they can work together in swarms, react to changing conditions and communicate with a main control centre. These capabilities are being combined into vehicles like its PingGuin
Popoto Modem announces V2.7 for Underwater Acoustic Modem
Popoto Modem announces Version 2.7 of its acoustic modem, designed to be a low cost, small scale, JANUS compliant underwater communications and control operations. The upgraded version offers expanded features and improved ease of deployment in both OEM and fully enclosed configurations.“We remain committed to providing affordable and flexible solutions to ocean engineers, scientists, equipment designers and anyone interested advancing the underwater internet of things,” says John DellaMorte, CTO of Popoto Modem. With that in mind, the company improved the user interface, adding online

it has also procured four autonomous underwater robots from ecoSUB robotics, with funding from NERC."Their sophisticated sensors are designed to provide crucial scientific data and the flotilla of new generation subs, the largest in the UK, is uniquely integrated together using acoustic underwater communications. This means the subs will be able to perform multi-vehicle synchronized surveys with accurate underwater positioning and can communicate with the PML Pioneer," PML added."Plymouth’s new fleet is unique in its field thanks to ‘Smart Sound Connect’, a £1
What's In Store for 2021? More Remote, More Data, More Autonomy
to site while remote technologies mean less people offshore.”ElectrificationSome of the underlying technologies that enable remote operations and autonomy have become increasingly available over recent years, from terrestrial communications, including satellite and marine 4G networks, to underwater communications, including free-space optics, acoustics radio, and hybrid systems, says Ling.Emerging low earth orbit satellites will further expand what’s possible.But another enabler may also finally come to market: subsea electrification. Subsea electrification could enable increased use of subsea
Ocean Startup Challenge Shortlists 31 Companies for Prize
;The shortlisted solutions involve environmental monitoring, reducing marine mammal entanglement in fishing gear, artificial intelligence, autonomous vehicles, technologies to reduce corrosion and biofouling, networks of sensors and analysis tools, sustainable bait alternatives, vision systems, underwater communications and IoT networks, value-added by-products, fish health, and much more.Nearly two-thirds of shortlisted companies proposed ways to overcome challenges in fisheries and aquaculture. Many of them touched on other challenge areas too, including a fifth of the applicants bringing forward solutions

exercises like Dynamic Mongoose, which are annual ASW trials in the GI-UK gap. We actually were part of the exercise this year, and we’ll do it again in 2019. We’ve participated in Dynamic Monarch, a distressed submarine exercise where we were able to use our digital underwater communications protocol to chat with the submarine that was playing the distressed submarine. Instead of trying to understand the garbled underwater telephone, we used an application we called “WetsApp,” which is sort of an underwater WhatsApp, based on our JANUS digital underwater communicat
