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

Researchers Study Unique Arctic Channel

A scientific study describes for the first time the submarine cartography of a high-latitude system in a channel covers tens of kilometers in the northern western area of the Barents Sea, in the Arctic Ocean. The Interfan Bear Island and Storfjorden (IBIS) channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during the Last Glacial Maximum (LGM), according to the new study published in the journal Arktos – The Journal of Arctic Geosciences.Terra incognita: discovering the planet’s sea floorsMany unknown landscapes in our planet are under

"Over the next 12 months, we will continue to work together and support the expedition remotely through our Mapping Cloud service," he said

the seas of the Arctic will see buoys deployed in the Barents Sea, and further into Arctic waters, in Summer 2019.“The maritime areas in the High North are the new frontier for oceanographic study and more research is crucial. In particular, with polar ice decreasing, we need to understand how Arctic ocean life will be impacted,” said Dr Pierre-Marie Poulain, Principal Scientist and Project Leader at CMRE. Furthermore, Arctic research becomes fundamental to guarantee safe and secure maritime traffic in the new routes around the North Pole. Thousands of SPOT Trace units are used for oceanograph

Arctic Sea Ice is Youngest and Thinnest Now

The Arctic Ocean's blanket of sea ice has changed since 1958 from predominantly older, thicker ice to mostly younger, thinner ice, according to new research published by NASA scientist Ron Kwok of the Jet Propulsion Laboratory, Pasadena, California.With so little thick, old ice left, the rate of decrease in ice thickness has slowed. New ice grows faster but is more vulnerable to weather and wind, so ice thickness is now more variable, rather than dominated by the effect of global warming, according to NASA's Earth Science News Team.Working from a combination of satellite records and declassified
