#Oi2020 History

100-foot tether connects Hercules to Argus. By keeping the tether between Argus and Hercules slack, Argus can then absorb the brunt of any ship movements, so that Hercules can remain stable and collect HD video from the seafloor. Argus’ HD video camera is similar to Hercules in that its large lights illuminate the area. The overhead view from Argus then allows pilots and scientists a higher-level view around Hercules. With Argus thrusters controlling the heading, pilots “flying” the ROV (while sitting in E/V Nautilus control room) can then aim the video cameras toward Hercules and

Armstrong Marine Delivers R/V to University of AK

last year, the University selected Armstrong Marine’s proposal to design and build the vessel.Nanuq is customized for research and teaching operations. The monohull features 28 – 32 knot cruise speed, hydraulic A-frame, overnight accommodations for five, full-service galley, head, Northern Lights 5kW diesel generator, and a Garmin/NMEA electronics package supplemented with a Furuno SC70 satellite compass.After Nanuq’s maiden 11-day voyage in and around Prince William Sound, Captain Brian Mullaly commented, “the boat performed beyond the scientists’ expectations.

AML MVP to Augment NSCC’s Seafloor Mapping

. With its unique ability to conduct real-time, vertical profiles continuously and automatically, the MVP200 is expected to improve the efficiency and quality of data collection.Looking to add ground-truthing to the process of multibeam data acquisition, AML and NSCC are working together to integrate lights and a high-resolution camera to the tow body that houses the underway profiling system’s sound velocity (SV), conductivity-temperature-depth (CTD), or multiparameter instrumentation. Ground-truthing is a critical step in validating the seafloor characteristics (e.g. seafloor sediments and habitats)

DOE Introduces Phantom X8 ROV

and two vertical 2.2 kW Tecnadyne brushless thrusters, the Phantom X8 has complete control and authority in any given direction, even in the toughest currents.For clarity underwater, the Phantom X8 boasts high definition (1080p) front (+/-90°) (pan optional) and rear (low light) cameras with 3 LED lights emitting 30,000 total Lumens with adjustable brightness controlled by the pilot control box or GUI. Auto functions for heading, altitude, depth, and positioning guide and control the ROV for diligent underwater tasks and inspections.The Phantom X8's performance at depths up to 1,000 meters is

winds, soaking our shoes in saltwater.A day later, the dust has cleared, and what do we know? We found the squid after only five Medusa deployments, despite the fact that thousands of ROV and submersible dives in the Gulf of Mexico have not done so. This suggests that the animal does not like the bright lights of ROVs and that stealth monitoring of the sort possible with the Medusa can allow us to see what has never been seen before.We also found it here, only about 100 miles southeast of New Orleans. The old maps often showed serpents at the edge, with the warning "here be monsters." However

BIRNS Celebrates 65 Years

exponentially changed, and connectivity solutions for today's subsea systems are extremely advanced and complex.BIRNS was born in Los Angeles and quickly became known for contributing key technology to the marine and nuclear industries. Early marine market contributions included building specialty lights for the Sea Lab projects and illuminating the excavation of the Titanic.Throughout its 65-year history, the company has helped advance technology in these markets, and its products have allowed faster communication and brighter illumination, both inside containment and at great oceanic depths.(Photos

Such training is absolutely essential for offshore workers and this demonstration showed just how effective

JW Fishers’ Dropped Video Systems for Aquaculture

; underwater video systems are a perfect tool for underwater research. The DV-2 dropped video system is a clear example of a video system that can be mounted in a frame and set on the floor of the ocean for fish observations in their natural habitat. The DV-2 comes standard with two 1200 lumen LED lights, 150’ of Kevlar reinforced cable and a 500’ depth rated housing.Sweeney International Marine Corp. and SIMCorp Marine Environmental Inc., operating under the umbrella of SIMCorp, are professional companies with extensive experience in the field of aquaculture. SIMCorp operates out of

Unheard Underwater: Covert Communications

. Free space optical modems are also not that covert, they operate in the visible light spectrum and are therefore visible to the naked eye.UltravioletWe set out to address the challenge of interference first. If we were to operate outside the visible light spectrum, to avoid interference from artificial lights, which wavelength would be the best choice? A centre wavelength of 405nm was a good compromise containing ultraviolet (UV) and some visible violet light, the BlueComm 200 UV was born. The concession we had to make was range. It has been effectively halved, to up to 75m. In exchange we gained two
