Research Expedition to Map Scottish Seabed

Slow Recovery of Coral Reef Shows Impact of Bottom Trawling
Newly developed 3D imaging technology has allowed scientists to map Darwin Mounds, a unique area of cold-water coral reefs off the coast of Scotland, to see whether it has recovered since being declared a Marine Protected Area sixteen years ago. The images show that in areas of the Darwin Mounds that had been heavily trawled, coral growth is still very sparse, and there has been no real recolonization. However, healthy coral growth was found in parts that had only been minimally damaged by bottom trawling, indicating that marine conservation measures are most effective when they are put in place before damage occurs....

TDI-Brooks Completes Multibeam Phase for TGS Offshore Nigeria

TDI-Brooks International (under contract to TGS) has completed the offshore multibeam phase offshore the Niger Delta. This survey took place in water depths of 750 to 3,500 metres and is Nigeria’s first regional multi-client Multibeam and Seafloor Sampling (MB&SS) study. TDI-Brooks’ R/V Gyre acquired 82,000 square kilometres of high-resolution hull-mounted multibeam echo sounder data. During the multibeam data collection, a total of 1,223 active hydrocarbon seeps were detected in the multibeam water column data. Onboard hydrocarbon seep analysis was conducted in near real-time onboard the vessel to expedite the process of core selection. The Gyre is fitted with an EM302 MBES... (read more)

How a Hydrographic and Ocean Technology Provider Organizes Interactive Presentations

What kinds of webinars appeal to the ocean technology community in these extraordinary times? Hydrographic and ocean technology provider Nortek has learnt that interactive digital events with an emphasis on learning and practical examples have a massive appeal. The Norway-based company has recently launched a live webinar series with over 20 classes and interactive presentations. These are tailor-made for people working with ocean technology, such as oceanography, subsea navigation, marine navigation and ocean surveying. The educational webinar series covers everything from real-time data collection near the coast to using acoustic Doppler current profilers (ADCPs) to estimate suspended sediment properly and how to get accurate...

Why Ocean’s Biological Carbon Pump Has Been Drastically Underestimated

Video Included
Every spring in the Northern hemisphere, the ocean surface erupts in a massive bloom of phytoplankton. Like plants, these single-celled floating organisms use photosynthesis to turn light into energy, consuming carbon dioxide and releasing oxygen in the process. When phytoplankton dies or is eaten by zooplankton, the carbon-rich fragments sink deeper into the ocean, where they are, in turn, eaten by other creatures or buried in sediments. This process is key to the 'biological carbon pump', an important part of the global carbon cycle. Capturing Carbon from the Atmosphere Scientists have long known that the ocean plays an essential role... (read more)

Venice Canals Look Clearer Due to Italy's Coronavirus Lockdown

Although in the first place the coronavirus has a huge impact on our daily lives and poses a serious threat to many of us, the outbreak of the disease has some remarkable side effects. For example, due to a lack of debris from tourists and near-zero boat traffic under Italy's ongoing coronavirus lockdown, the city of Venice is enjoying crystal clear waters in its world-famous canals. Even dolphins have been spotted in the canals. The clear waters are a tiny bright spot in the city, whose economy has been virtually wiped out since tourists fled the area at the beginning...

Fugro Secures Large Marine Survey Contract

INPEX Masela, Ltd. (INPEX), a subsidiary of INPEX CORPORATION, has awarded Fugro a large marine survey contract for the Abadi liquefied natural gas (LNG) project in Indonesia. Fugro will perform geophysical and geotechnical surveys and the associated studies needed to support front-end engineering design (FEED) for offshore production facilities and the submarine pipeline to the onshore LNG terminal. Geodata will be acquired using Fugro’s deepwater autonomous underwater vehicle (AUV) Echo Surveyor and their robotic seafloor drill, Seafloor Drill 2, deployed from Indonesian support vessels. Engineering Challenges The Abadi LNG project is based on an onshore LNG development scheme that INPEX,... (read more)

Chartwell Marine Launches Scanwell Shallow Draft Survey Vessel

In response to calls from the scientific community, ports and industrial surveyors, Chartwell Marine, a pioneer in next-generation vessel design, has announced the launch of its Scanwell shallow draft survey vessel providing unparalleled standards of versatility and safety in one and half metre waters. The Scanwell range is available in multiple hull sizes – 10m, 12m, 15m and 19m – enabling use in a wide variety of applications, such as offshore energy, port infrastructure and scientific expeditions. There are already two vessels on order, the company says, the first of which has been recently delivered, a 10m survey vessel and... (read more)

Scientists Drill for First Time on Remote Antarctic Glacier

Teams from the US and the UK have successfully completed scientific fieldwork in one of the most remote and hostile areas of West Antarctica – coinciding with the 200th anniversary of the discovery of the continent. This research will help scientists determine whether Thwaites Glacier may collapse in the next few decades and affect future global sea-level rise. Thwaites Glacier, covering 192,000 square kilometres (74,000 square miles) an area the size of Florida or Great Britain, is particularly susceptible to climate and ocean changes. Over the past 30 years, the amount of ice flowing out of Thwaites and its neighbouring... (read more)

People Living On Deltas Are Increasingly Vulnerable to Sea-level Rise

Researchers from Utrecht University in the Netherlands, Woods Hole Oceanographic Institution (WHOI) in the US, and colleagues found that delta areas worldwide have actually gained land in the past 30 years, despite river damming. However, recent land gains are unlikely to last throughout the 21st century due to expected, accelerated sea-level rise. The researchers published their findings in the journal Nature. Economically and Ecologically Valuable River deltas rank among the most economically and ecologically valuable environments on Earth. People living on deltas are increasingly vulnerable to sea-level rise and coastal hazards such as major storms, extremely high tides, and tsunamis.... (read more)

Fugro And Colombian Maritime Authority Complete Seep Hunting Study

Fugro and the Colombian Maritime Authority (Dirección General Maritima, DIMAR) have completed a joint environmental seep hunting study to help assess the country’s resource potential in the Caribbean Sea. The study involved shallow water seabed sediment coring, geochemical analyses, and seabed heat flow measurements. Fugro also provided classroom and vessel-based training to DIMAR personnel. “This project and training were carried out to support DIMAR’s strategic objectives, including developing the skills of our personnel, and producing technical and scientific information to support Colombia’s maritime authority,” stated Petty Officer First Class Luis Olarte, project manager for DIMAR.
