USV Completes First Autonomous Circumnavigation of Antarctica

High-quality and Reliable Data Is Needed for Research Use
A 7m (23ft) long, wind-powered unmanned surface vehicle (USV) has become the first unmanned system to circumnavigate Antarctica. Known as SD 1020 and equipped with a suite of science-grade sensors, the vehicle collected data in previously uncharted waters, enabling new key insights into ocean and climate processes.

USV SD 1020 left for the 196-day mission from Southport in Bluff, New Zealand, on 19 January 2019. It returned to the same port on 3 August after sailing over 22,000km (13,670 miles or 11,879 nautical miles) around Antarctica. During the mission, the vehicle survived freezing temperatures, 15m (50ft) waves, 130km/h (80mph) winds... (read more)

Flanders Marine Institute in Belgium Takes Delivery of a Gavia AUV

Teledyne Gavia announced that it has completed the sale and recent Sea Acceptance Testing of a Gavia AUV to the Flanders Marine Institute (VLIZ) in Oostende, Belgium. The VLIZ Gavia is rated to 1,000m depth in a low logistics form factor and includes an array of scientific instruments to meet current and future VLIZ research requirements. The modular nature of the GAVIA AUV allows sensors to be added as mission requirements dictate. The VLIZ Gavia is configured for diverse research applications and includes an iXblue INS, coupled with a Teledyne RD Instruments Pathfinder ADCP up/down for highly accurate navigation and...

Unmanned Vehicle Deploys ADCP Mooring Near Calving Ice Cliff

Global concern about rising sea levels has thrust increasing loss of glaciers and ice sheets into public attention. A key uncertainty in projections of sea level rise is the rate of ice loss at the seaward margin of glaciers. The glaciers of Greenland and Alaska that reach the sea have therefore received increased scientific notice. Yet the ways in which warm ocean water interacts with and erodes the face of these glaciers have been largely unobserved. Difficult and Dangerous Operating near an ice cliff that is actively calving icebergs - above and below the water line - is both difficult... (read more)

CSA Completes Field Surveys Offshore Puerto Rico

CSA Ocean Sciences (CSA), under a subcontract to Jacobs, has announced the completion of a comprehensive environmental monitoring survey. The survey included physical, biological and chemical field sampling and data collection for 301(h) waiver demonstrations at the Aguadilla, Arecibo and Ponce Regional Wastewater Treatment Plant (RWWTP) outfalls offshore Puerto Rico for the Puerto Rico Aqueduct Authority (PRASA). Since 1999, CSA has been helping to evaluate compliance with receiving water quality standards and describe environmental conditions. Acoustic Doppler Current Profilers During this recent survey, CSA deployed and retrieved acoustic Doppler current profilers (ADCPs), a conductivity-temperature-depth (CTD) water profiler with ancillary sensors...

New, High-performing USV for Ocean Surveying

A new unmanned surface vehicle (USV) designed for the Chinese market offers an open and low-cost platform to measure water current and direction. Nortek China has integrated Doppler instrumentation on the vehicle to help better meet user requirements for ocean surveying. The new USV has an industrial personal computer (IPC) as the main operation platform and uses Remote Desktop, a remote control technique, to communicate with all the instruments installed. This means that the vehicle offers an open and low-cost platform for customers who need to carry out several different tasks at the same time. For example, users can perform... (read more)

Design to Deployment - ToughBoy Wave Buoy

When using sea-going equipment, the elements are invariably one of your greatest adversaries. Whether a researcher waiting for a weather window, or a technician maintaining a sensor platform, the waves and weather should never be underestimated as sensor equipment must endure these conditions. Wave buoys represent a considerable design challenge from multiple perspectives. Physical durability is clearly of fundamental importance, but that robustness must be extended into the functionality and performance of the wave buoy system. A wave buoy must also maintain operational independence over extended periods of time – measured not in weeks or months, but often years. The... (read more)

Hydrographic Surveying: Where Do We Stand

The Ever-increasing Accuracy of Mapping the Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those within the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared to... (read more)

Unmanned Surface Vehicles Monitoring Lava Flow

Going Where No Humans Should Go
The Kilauea volcano eruption on Hawaii’s Big Island has captivated the world. The images broadcasted each day convey the power of the molten lava flowing from the Kilauea volcano to the sea. Its continuous flow is devastating neighbourhoods and communities, has filled pristine Kapoho Bay, and is ultimately changing the shape of the Big Island of Hawaii forever.  Kilauea’s eruption provides a rare scientific opportunity to study the impact of the lava flow on the ocean and its marine life. However, collecting ocean data during a live volcanic event, is extremely difficult and as a result rare. In recent history... (read more)
