AUV Case Study: Marine Roboticists are Turning AUV Sight into Perception

In 2018, marine robotics scientist Arjuna Balasuriya was at the Advanced Naval Technology Exercise (ANTX) in Newport, Rhode Island, testing new software for an autonomous underwater vehicle (AUV). In the past, his AUV research had meant long ocean cruises in rough choppy waters, but for the moment, he was analyzing his algorithms from a comfortable dry seat on land.Balasuriya and his team from Charles River Analytics were developing an app for the AUVs made by Teledyne Gavia, which could navigate on their own in the oceans to take sonar surveys of the seafloor. But to be truly autonomous, they needed

The ocean is indeed known to be the only true net sink for anthropogenic carbon dioxide (CO2) and without this oceanic uptake, atmospheric CO2 would be significantly higher today than what is currently observed. The impact of this ocean acidification can already be perceived and current projections suggest that those changes will persist

WHOI: Ocean “Pumped” to Capture More Atmospheric Carbon

While scientists have long known the essential role that the ocean plays in capturing atmospheric carbon, a new study from Woods Hole Oceanographic Institution (WHOI) shows the efficiency of this natural pump has been underestimated.The ocean’s “biological pump” is a critical part of the global carbon cycle and relies on phytoplankton, single-cell organisms that use photosynthesis to turn light into energy—consuming carbon dioxide and releasing oxygen in the process. When phytoplankton die or are eaten by zooplankton, carbon-rich fragments sink into the ocean, then consumed by

Brazilian geoscience services company OceanPact Geociências has chosen deep water positioning technology from Sonardyne Brasil Ltda. to support its geophysical, geotechnical and environmental research operations across the region.Ranger 2 Ultra-Short Baseline (USBL) systems have been installed on board OceanPact’s research vessels Seward Johnson and Austral Abrolhos, both currently on hire to Brazilian oil major Petrobras. The systems will be used to precisely track the location of underwater equipment and sensor packages deployed from the ships, including seabed corers, towed sensors and

Hybrid AUV Completes Depth of Burial Survey for Offshore Wind Farm

Modus Seabed Intervention completed a high speed bathymetric and depth of burial survey of the inter array cable routes on the innogy operated Gwynt-y-Môr offshore wind farm, using the Modus HAUV-2 (Hybrid Autonomous Underwater Vehicle) .The Gwynt-y-Môr Offshore Wind Farm comprises 160 Siemens 3.6MW WTGs located approximately 8 miles from the North Wales coast in Liverpool Bay in water depths ranging between 12m and 28m.  The WTG’s are connected by 161 inter array cables which total circa 147km in length. The worksite is known for high subsea currents, so any solution had to

RS Aqua launches WaveRadar REX2

RS Aqua launched its next generation WaveRadar, the WaveRadar REX2. In been in development for several years, the WaveRadar REX2 is half the size and weight of the legacy REX, consuming 10 times less power while offering a 25% greater range and still maintaining its accuracy.The WaveRadar REX2 is powered by a new Emerson microwave sensor, using the same Frequency Modulated Continuous Wave (FMCW) measurement technique that has been used by the WaveRadar REX over the past 20 years. This new higher frequency sampling unit enables a greater measurement range of up to 80 m, and the same high accuracy over

Sonardyne Tests Autonomous Vehicles Navigation for UK MOD

Marine robotics company Sonardyne International Ltd. demonstrated technologies that will aid autonomous vehicle operations in challenging environments under a project funded by the UK’s national Defense and Security Accelerator (DASA).Working with a 12-meter-long SEA-KIT X class unmanned surface vehicle (USV), Sonardyne tested and validated sensors already used by unmanned underwater vehicles for use on USVs in support of missions in coastal watersSpecifically, Sonardyne’s SPRINT-Nav hybrid inertial navigation instrument was integrated into a SEA-KIT X and tested against local real-time

Near- or Below-normal Hurricane Season Predicted for Central Pacific

has four or five tropical cyclones.“This year we will likely see less activity in the Central Pacific region compared to more active seasons,” said Gerry Bell, Ph.D., NOAA’s lead seasonal hurricane forecaster at the Climate Prediction Center. “Less activity is predicted since ocean temperatures are likely to be near-average in the central and eastern Pacific Ocean where hurricanes form, and because El Nino is not present to increase the activity.”This outlook is a general guide to the overall seasonal tropical cyclone activity in the Central Pacific basin, and does not

BAE Reflects One Year after Takeover of Riptide

One year ago, the FAST Labs R&D arm of BAE Systems announced the acquisition of Riptide Autonomous Solutions, with the goal  to pair Riptide’s unmanned underwater vehicles (UUV) with BAE's mission system capabilities in autonomy, navigation, communications, sensor processing and electronic warfare, among others. The Riptide family of UUVs includes three offerings: the 4.875” diameter (25 lbs.) micro, the 7.5" diameter (65 to 120 lbs.) 1MP (man-portable) unit and the 9" (9.375”) diameter (120 to 240 lbs.) 2MP. The family of unmanned vehicles are designed to
