Scientists Find Micro Plastic in Arctic Ice
Foundation and the Heising-Simons Foundation in the United States, the expedition in the Swedish icebreaker Oden ran from July 18 to Aug. 4 and covered some 2,000 nautical miles.Separately, German and Swiss scientists published a study on Wednesday based on samples from the Arctic, Swiss Alps and Germany that suggested microplastic is being blown vast distances through the air and dumped when it snows.The team from the Helmholtz Centre for Polar and Marine Research found that snow collected on the Norwegian Arctic archipelago of Svalbard contained up to 14,400 particles of plastic per litre.

how these two things relate to one another in the long term, we’ll need to wait for a longer stretch of observational records to become available,” he said.Also collaborating on the study were Glen G. Gawarkiewicz and Jiayan Yang of WHOI; Sönke Dangendorf of Universität Siegen in Germany; and Christopher M. Little and Rui M. Ponte of Atmospheric and Environmental Research, Inc.The work was supported by National Science Foundation (NSF) awards OCE-1558966, OCE-1834739, and OCE-1805029; NASA contract NNH16CT01C; and the J.

Poland Employs New Seismic Tech
.The new technology makes a perfect solution for locating hot springs, as proven by Geofizyka Toruń’s survey conducted this year in the Netherlands. At present, the company is conducting seismic work in Hungary, and in the autumn of this year it will commence nodal seismic data acquisition in Germany. It will be the largest seismic survey in Europe in terms of the number of nodes deployed and the volume of data recorded.Wireless seismic surveying technology has been developed for years, but only now has miniaturisation of components reached satisfactory levels. The previously developed solutions
Offshore Wind – A Brief History
Jersey, Massachusetts and Virginia. Globally, (2017 data) 3,387 MW of offshore wind capacity was commissioned, resulting in a cumulative installed global capacity of 16.3 GW. The United Kingdom is the largest offshore wind market with 5,824 MW of cumulative installed capacity, followed by Germany (4,667 MW), China (1,823 MW), Denmark (1,399 MW), and the Netherlands (1,124 MW).DOE reports that globally, auction prices continue to fall. In 2017, developers placed four bids that were termed as “zero-subsidy.&rdquo
Robotics: The Next Gen in Subsea Vehicles
long distances to swarms of drop deployed ocean bottom nodes that can find their way to pre-programmed locations.At energy:connected, as the Oslo-based Subsea Valley cluster and annual conference is now called, some of these concepts were outlined, including those from two Norwegian technology firms and Germany’s Thyssenkrupp, a firm more used to designing naval submarine systems. uSEA unveils uLARSOne, Norwegian technology start-up uSEA, is proposing a hybrid system to disrupt existing manned vessel supported subsea operations via a subsea and surface drone combination.uSEA was founded in
Case Study: Cables in Underwater Missions
has now used the custom cable for dozens of missions, in regions as diverse as the Arctic to the tropical waters of Polynesia. It has proven ideal for the expeditions, carried out every two years since 2008. It is set to be deployed again in 2021. Near identical cables are now in use in China, Germany, India and Antarctica.We’ve learned through experience that cables used in dynamic subsea environments have to be custom designed and built for the specific harsh environments our customers encounter. The properties of synthetic strength members and outer jackets can make the difference to
Subsea Mining: The Next Big Thing for UUVs
mining companies understand the contours of an underwater mine. Impressively, INESC TEC is also a key outfitter for this Europe-wide research success story that involved 17 consortium partners from nine European countries, including robot developers SMD and BMT (UK), DAMEN (the Netherlands) and SANDVIK (Germany).Versatile: The offshore and inland HROV, EVA.

Pioneering Spirit Shifts to the North Sea
said. "The other construction works are on track to complete the twin pipelines by the end of 2019."Nord Stream 2 is being built to transport gas from Russia into Europe. So far, more than 800 kilometers of pipes have been laid on the seabed for the project in line with the permits granted by Germany, Finland, Sweden and Russia. Currently there are more than 1,000 people working on some 20 vessels for the project.Pioneering Spirit installing pipeline in Swedish waters (Photo: Nord Stream 2
Walter Munk: 1917-2019
was admitted as a PhD candidate.Then-Director Harald Sverdrup would become a lifelong friend and mentor to Munk, who also became fast friends upon joining Scripps with Roger Revelle, a research oceanographer who had just received his doctorate.Munk became an American citizen in 1939 and when war with Germany seemed imminent, he joined the U.S. Army, serving in the 146th Field Artillery, 41st Division at Fort Lewis, Wash. Sverdrup, however, requested his recall in 1941 and Munk returned to Scripps to begin work at the new U.S. Navy Radio and Sound Laboratory in the San Diego neighborhood of Point Loma
New Submarine Cable System for Canada
mm² 69 kV three-core submarine cable system with XLPE insulation for a total of 20 km. All submarine core cables will be produced at Prysmian’s center of excellence in Montereau (France), while the cable armoring will be manufactured at Prysmian’s state-of-the-art factory in Nordenham (Germany), part of the Group after the merger with General Cable. Completion of the project is scheduled for October 2019.The first cable will run approximately for 3.5 km from the Cable Riser Station at Chocolate Cove, on the east side of Deer Island, to a Cable Riser Station at Wilson’s Beach, on
