Airborne Hydrographic Survey Commissioned After NZ Earthquake

of the South Island.   RAN LADS commanding officer, Flight Lieutenant Commander Susanna Hung, explained the mission. “We will fly over the area and collect hydrographic survey data, which will reveal what has happened below the waterline, and identify any shifts in the ocean floor which mariners need to be aware of.”   The RAN’s Airborne LiDAR Bathymetry (ALB) system has been developed by Fugro for safe, high speed and cost effective surveys of shallow coastal areas. Under a long term contract to the RAN, Fugro provides the LADS technology, a de Havilland Dash 8-202

Expedition to Study Ocean’s Role in Glacial Melting

understand how the Southern Ocean is changing and how these changes are likely to affect the East Antarctic ice sheet.   A team of around 30 scientists, technicians and PhD students from CSIRO, the Antarctic Climate & Ecosystems CRC (ACE CRC), the University of Tasmania’s Institute for Marine & Antarctic Studies, and the Australian Antarctic Division will leave from Hobart on Australia’s icebreaker Aurora Australis today (Thursday).   Chief Investigator and CSIRO Oceans and Atmosphere scientist, Dr. Steve Rintoul, said the team hopes to reach areas surrounding the Totten

Boeing and Liquid Robotics have collaborated on extensive integration on the Sensor Hosting Autonomous Remote Craft (SHARC), a version of the Wave Glider, since 2014. The SHARC, integrated with Boeing’s advanced sensors, connects intelligence, surveillance and reconnaissance capabilities ranging from satellites to manned and unmanned aircraft to sub-surface crafts.

Boeing to Acquire Liquid Robotics

Aiming to grow its seabed-to-space autonomous capabilities, Boeing said it has entered into an agreement to acquire Liquid Robotics, developer of the Wave Glider ocean surface robot.   “With Liquid Robotics’ innovative technology and Boeing’s leading intelligence, surveillance and reconnaissance solutions, we are helping our customers address maritime challenges in ways that make existing platforms smarter, missions safer and operations more efficient,” said Leanne Caret, president and CEO of Boeing Defense, Space & Security.   In September 2014, Boeing and

Ocean Glider Equipped with Fishery Echosounder

NOAA's Beaufort Laboratory (National Centers for Coastal Ocean Science and Southeast Fisheries Science Center) collaborated with the Center for Ocean Technology and College of Marine Science of the University of South Florida to instrument an echosounder into an ocean gilder to extend surveys of pelagic and demersal fishes associated with rocky reefs in the Gulf of Mexico and Southeast U.S. Atlantic.   ASL Environmental Sciences (ASL) supplied a purpose-built 200 kHz single-frequency scientific echosounder, a modification of ASL's proven Acoustic Zooplankton and Fish Profiler (AZFP), to Teledyne

Copenhagen Subsea: New Milestone for Thruster Reliability

Copenhagen Subsea A/S is introducing a new standard for testing subsea thrusters    The new standard for testing subsea thrusters implemented by Copenhagen Subsea A/S dictates a remarkable 1,000 working hours of continuous operation at maximum power. Once tested and validated, the thruster must still maintain full functionality and unaffected performance.   When operating in open water, the cost of a failing subsea thruster is critical. Every malfunction, delay or maintenance-break related to the subsea exploration vessel will set back the entire operation. Imagine for a moment this
