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...

Shipwreck Monitoring in the North Sea

Surveyors Discover World War One Submarine
In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its homeport of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine. In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its home port of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine.  As an executive agency of the Dutch Ministry of Infrastructure and Water Management, Rijkswaterstaat facilitates smooth and safe maritime traffic in the Dutch North Sea. One of its activities is an annual seabed monitoring programme. Apart from a few deeper spots, the Dutch part of the North Sea is in general 35 metres deep, while the coastal... (read more)

Strong Gulfstream System in the Miocene Does Not Contradict Models

Differences in salinity of water masses drive the global ocean circulation. Model simulations show that the circulation can be weakened by high freshwater input in key regions. Until now, a strong Gulf Stream system in the Miocene about ten million years ago seemed to contradict this assumption. At that time, the land bridge between North and South America was not yet closed and relatively fresh water from the Pacific reached the Atlantic. A study by scientists from the GEOMAR Helmholtz Centre for Ocean Research in Kiel (Germany), published in the international journal Nature Communications, resolves this contradiction. Global Ocean Currents... (read more)

Divers Find What is Thought to be the Earliest Boatbuilding Site in the World

An 8,000-year-old wooden platform has been discovered off the Isle of Wight coast near Yarmouth in the UK,  BBC News reports. The seabed where the structure was found—at a depth of roughly 36 feet—would have been dry land when the platform was built, and still connected to the European mainland. The platform sits adjacent to and may have been part of Bouldnor Cliff, a submerged Mesolithic settlement first identified in 1999, which—among a number of discoveries—has yielded what is thought to be the earliest boatbuilding site in the world. Divers from the Maritime Archaeology Trust, which oversees the site, first spotted... (read more)

Research Vessel Polarstern Departs for the Arctic MOSAiC Expedition

Video Included
On the evening of 10 August 2019, the German research vessel Polarstern left her homeport in Bremerhaven, Germany and set course for the Arctic. The purpose of the expedition is to conduct studies at a major long-term monitoring station, the AWI’s Hausgarten observatory in the Fram Strait. Experts from various disciplines are investigating all aspects of the ecosystem, from the water’s surface to the ocean depths, in order to determine the impacts of climate change on biodiversity in the Arctic. After roughly a month underway, Polarstern will reach the Norwegian port of Tromsø in mid-September, where she’ll receive her final... (read more)

Study Reveals Impact of Mining on Coral Reefs

A study from The Australian National University (ANU) shows the impact phosphate mining is having on our coral reefs. The study looked at coral reefs around Christmas Island (Australia), where there's been extensive phosphate mining for around a hundred years. Lead researcher Dr Jennie Mallela says in areas near the island's mining 'hot spots' the reef showed high levels of pollution that has caused a slowdown in reef growth and diversity. Pollution Reduces the Light Levels "The major problem is sediment pollution from the phosphate mine. On a healthy reef, the sediment will be made from reef organisms—including worn down...

Report Warns of Irreversible Harm from Deep-sea Mining

The world’s oceans could face severe and irreversible harm unless tighter environmental safeguards are put in place to protect them from the risks of deep-sea mining, warns a new report titled 'In Deep Water', released by Greenpeace International. Shining a light on this emerging threat, the report reveals that the deep-sea mining industry is aware that their activities could result in the extinction of unique species and calls on governments to agree on a strong Global Ocean Treaty at the United Nations that puts conservation, not exploitation, at the heart of ocean governance. Largest Ecosystem on the Planet “The health of our oceans is... (read more)

Netherlands and USA Cooperate in Environmental Security Certification Programme

Partrac GeoMarine, a Houston, USA, based Marine Survey and Consultancy company, has announced the award by the US Department of Defense (DoD) of a 3-year contract to demonstrate a new tool for mapping the in situ distribution of Contaminants of Concern (COCs) in aquatic sediments. The award is part of the Environmental Security Technology Certification Program (ESTCP), the DoD's environmental technology demonstration and validation programme. Partrac, together with its Netherlands based partner Medusa Explorations, will deploy the new instrument at up to three contaminated DoD Superfund sites to map the distribution of COCs such as Polycyclic Aromatic Hydrocarbons (PAHs), Polychlorinated Biphenyls...

iXblue Conducts toFuture Groix & Belle-Île Pilot Wind Farm Geophysical Survey

iXblue’s Sea Operations division has been selected by EOLFI, the “Ferme Eolienne Flottante de Groix & Belle-Île” delegated project contractor, to conduct the geophysical survey of the future Groix & Belle-Île pilot wind farm located in the South of Brittany, off the West coast of France. The survey, that began earlier this week, will last for about five days and will be conducted by a dedicated crew of 5 iXblue hydrographic surveyors and geophysicist engineers onboard the company’s own Marine Renewable Energy (MRE) hydrographic research vessel, FeliX. "Our vessel has been designed and manufactured by our own shipyard and survey... (read more)

Definitive Global Map of Ocean Floor Doubles Data

The data available to produce the definitive map of the world’s ocean floor has more than doubled, just two years after the launch of an international effort to produce a complete map by the year 2030. Following the efforts of The Nippon Foundation-GEBCO Seabed 2030 Project, coverage of the world’s ocean floor has now increased from 6% to 15%. This is equivalent to around 32,000,000 square kilometres of bathymetric data, an area greater than the landmass of African. Heeding the call from Seabed 2030, the industry is now making significant contributions to the mission with around 570,000 square kilometres of... (read more)
