Fugro Completes Deepwater AUV Surveys for Shell in US Gulf of Mexico

Fugro has completed several high-resolution geophysical surveys in the US Gulf of Mexico for the Shell International Exploration and Production Company. The project required data collection over multiple deepwater lease blocks in the greater Perdido and Mars development areas to support clearance of potential environmental, engineering, geological and archaeological hazards ahead of planned drilling activities. As the preferred contractor for this project, Fugro deployed a Hugin autonomous underwater vehicle (AUV) from its purpose-built survey vessel, the Fugro Brasilis. The Hugin AUV is depth-rated to 3000m and equipped with a multibeam echosounder, side-scan sonar and sub-bottom profiling sensors. As such, Fugro... (read more)

WASSP Launches New Rapid Deployment Multibeam Sounder

WASSP Multibeam has launched its new rapid deployment multibeam sounder – the W3 Rapid Deployment System (RDS). Revealed at the recently held Pacific Expo 2019 in Sydney, Australia, W3 RDS has been designed for navies, maritime police and search & rescue organizations for use where depths are unknown and to find safe navigation routes for larger vessels. When a fixed transducer installation in a small vessel such as a tender isn’t always practical, the W3 RDS has been designed around a portable Carbonfibre Mast that includes a transducer, motion sensor and satellite compass. This allows operators to deploy the unit... (read more)

Study Measures How Much of Corals' Nutrition Comes from Hunting

When it comes to feeding, corals have a few tricks up their sleeve. Most of their nutrients come from microscopic algae living inside of them, but if those algae aren't creating enough sustenance, corals can use their tentacles to grab and eat tiny prey swimming nearby. A new study from researchers at the Woods Hole Oceanographic Institution (WHOI), the University of New Mexico, and Scripps Institution of Oceanography is revealing that more of corals' nutrients come from this sort of hunting than previously expected, information that may help predict the fate of coral reefs as global ocean temperatures rise. The... (read more)

MSI completes a 520-day measurement programme

MSI has completed a 520-day measurement programme to support the feed of a Floating Storage and Regasification Unit (FSRU) and pipelines in Alexandroupolis, Greece. The Alexandroupolis Independent Natural Gas System (INGS) is a modern, cutting edge technology project which will supply natural gas to the Greek and Southeast European gas markets. The project comprises an offshore Liquefied Natural Gas (LNG) Floating Storage and Regasification Unit and a subsea and onshore gas transmission pipeline system. Expecting to begin commercial operations in 2022, the project is being implemented by GASTRADE S.A, a company that studies, designs, develops, operates and exploits infrastructures which are...

Researchers Use Drones to Weigh Whales

How do you weigh a living whale?  The obvious response is very carefully, but scientists can’t exactly put these large marine mammals on a scale. Researchers from Aarhus Institute of Advanced Studies (AIAS) in Denmark and Woods Hole Oceanographic Institution (WHOI) in the US devised a way to accurately estimate the weight of free-living whales using only aerial images taken by drones. The innovative method, published in the British Ecological Journal Methods in Ecology and Evolution, can be used to learn more about the physiology and ecology of whales. Body Volume and Mass of the Whales By measuring the body... (read more)

How Much Fishing Gear is Lost at Sea?

Abandoned, lost or otherwise discarded fishing gear or ‘ghost gear’ contributes substantially to global marine pollution, responsible for wide-reaching environmental and socioeconomic impacts. Until now, there has not been a clear global picture of the quantity and type of fishing gear lost worldwide. Using data from 68 studies published between 1975 and 2017, researchers have produced the first global estimate of commercial fishing gear losses in our oceans. “The study estimates that 6% of all fishing nets, 9% of all traps, and 29% of all lines are lost or discarded into our oceans each year,” explains Kelsey Richardson, a PhD...

Live Transmissions from the Deep

Exploring the World’s Most Unknown and Least Protected Ocean
Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located. Furthermore, researchers are often using advanced instruments that have never... (read more)

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.

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)

Ocean Discovery XPRIZE Winners Talk Tech in Tokyo with Japanese PM

Prior to being awarded the four million dollar grand prize in the Shell Ocean Discovery XPRIZE this May, the members of the international GEBCO-Nippon Foundation Alumni Team had found precious few opportunities to all meet face to face. For much of their three-year journey in the competition, communication was carried out remotely through email and Skype. A recent visit to Tokyo, however, offered a chance to sit down together and plan their next steps as a team and a broader network of alumni – as well as discuss the importance of ocean mapping with the Japanese Prime Minister. Meeting the PM... (read more)
