Arctic Sea Ice Lows Mark a New Polar Climate Regime

At the edge of the ice blanketing part of the Arctic Ocean, the ice looked sickly. Where thick sheets of ice once sat atop the water, now a layer of soft, spongey slush slid and bobbed atop the waves.From the deck of a research ship under a bright, clear sky, “ice pilot” Paul Ruzycki mused over how quickly the region was changing since he began helping ships spot and navigate between icebergs in 1996.“Not so long ago, I heard that we had 100 years before the Arctic would be ice free in the summer,” he said. “Then I heard 75 years, 25 years, and just recently I heard 15

The Ocean's Microplastics Mess: Technology & Technique to Identify & Clean Up

in Germany such as Heligoland, Bavaria and Bremen, as well as the Swiss Alps and the Arctic. In each location, the snow contained high concentrations of microplastics, even in the most remote of areas (in the Arctic, samples contained up to 14,400 particles per liter). When analyzing sea ice from the Arctic Ocean, the amount and distribution of microplastics was determined by using a Fourier Transform Infrared Spectrometer (FT-IR), a device that shines a beam of light containing multiple frequencies at once and measures how much light is absorbed. Depending on each particle’s unique composition,

New Depth Map Over the Arctic Ocean

Details of a new depth map of the Arctic Ocean have been published in the nature journal Scientific Data. The new portrayal of the Arctic Ocean floor is in the form of a digital gridded database and comprises Version 4.0 of the International Bathymetric Chart of the Arctic Ocean (IBCAO).The gridded compilation has been completed under the auspices of the Regional Center for the Arctic and North Pacific Ocean of The Nippon Foundation-GEBCO Seabed 2030 Project. This Regional Center is one of four Seabed 2030 centers covering the world ocean and is run jointly by Stockholm University and the University

China's Polar Icebreaker Embarks on First Arctic Mission

Xue Long 2 has set sail on its first mission to the Arctic, China's state-run Xinhua News Agency reports.Xuez Long 2 (Snow Dragon 2) departed Shanghai Wednesday with a team of Chinese scientists on board to conduct investigations in areas including the Chukchi Rise, Canada Basin and the central Arctic Ocean, Xinhua reports. The voyage is expected to cover some 12,000 nautical miles and conclude in late September.The expedition is said to be organized by China's Ministry of Natural Resources to study biodiversity and ecosystems, ocean acidification and chemical environment and new pollutants,

Forum ROV to Support Arctic Research

will be installed on board the Canadian research icebreaker CCGS Amundsen and will support the exploration of Arctic and Sub-arctic seafloor eco-systems. Equipped with 85 scientific systems, the CCGS Amundsen gives Canadian researchers and their international collaborators unprecedented access to the Arctic Ocean.Forum’s Sub-Atlantic Comanche ROV is equipped to a high specification with two seven-function manipulator arms for complex underwater procedures. It also has precision positioning and navigation systems, cameras, lighting and sonars for low visibility operations.The new asset will replace

#Oi2020 History

2015, researchers at the National Oceanography Center (NOC) used Royal Navy submarine data to investigate the nature of turbulence in the ocean beneath the Arctic sea-ice. This is mainly because recent decreases in Arctic sea ice may have a big impact on the circulation, chemistry and biology of the Arctic Ocean, because of ice-free waters becoming more turbulent. By revealing more about how these turbulent motions distribute energy within the ocean, the findings from this study provide information important for accurate predictions of the future of the Arctic Ocean. The melting of Arctic sea-ice is

the University of Manitoba under Dr. David Barber investigating how Arctic storms influence dynamic and thermodynamic processes in Arctic sea ice and across the ocean-sea ice atmosphere interface, and how these processes might change with climate change.  This project details an emerging ice-free Arctic ocean over the past decade that reveals a surface that absorbs and retains more solar radiation and thus is apt to be characterized by a delayed winter freeze-up, increased autumn storminess, and higher frequencies of large waves and swells.  Waves can propagate into the pack ice, causing flexural

#Oi2020: Subsea History

with the vessel that year he and his team discovered a 10,000-foot high seamount approximately 400 miles north of Barrow, Alaska, which they named the Healy Seamount.Thirteen years later, On September 23, 2016, (see photo) the Healy’s crewmembers prepared to deploy a dredging project in the Arctic Ocean. The mission was for the purpose of collecting rock samples from outcrops of a seafloor canyon. The project was unique in that today’s modern expeditions (such as this one) can now include sovereign rights to resources in icy areas that more than 10 years ago were inaccessible.Marine Technology

Remote-Controlled Submersible Fish Farm in Arctic Ocean

Digital technology leader ABB has won a contract from Arctic Offshore Farming to power its first-ever remote controlled submersible offshore salmon farm in the Arctic Ocean.ABB will provide a comprehensive package of its leading electrical, automation, instrumentation and telecom technologies that ensure maximum efficiency and minimal environmental impact.With the global market volume of salmon expected to hit 4.5 million tons by 2023, according to a 2018 report by Research and Markets, the Arctic Offshore Farming project is looking for ways to farm fish in a more sustainable manner.The submerged fish
