is also a transition towards all-electric trees. Siemens Energy has introduced a high-performance fiber optic wet-mate connector for subsea networks, supporting oil and gas and future offshore wind applications.The 2,350km subsea fiber optic Arctic Way Cable System will be located entirely within the Arctic Circle.Image courtesy Space NorwayAdditionally, efforts are being made to digitalize connectivity products. Siemens Energy is collaborating with UK universities to develop first-generation digital connectivity products as it explores ways of introducing health monitoring into its products to boost asset
Space Norway, SubCom Announce Contract-in-Force for Arctic Way Cable System
will produce the components for Arctic Way at its manufacturing campus in Newington, NH, USA. The trunk-and-branch, repeatered system will be approximately 2,350 km in length with direct shore end landings in Bodø, Norway, Jan Mayen, andLongyearbyen, Svalbard. Located entirely within the Arctic Circle (between 67-78°N), the system will be the world’s northernmost subsea cable system and will be installed by one of SubCom’s polar-certified, Reliance Class cable ships.“Establishing the new Arctic Way cable system is imperative to ensure that data connectivity for the Arctic

is instrumental in ensuring safe passage for naval and commercial vessels. The U.S. Navy has deployed REMUS in strategic waterways, including the Persian Gulf, the Baltic and Black Seas, while NATO allies have used the platform in joint exercises across the Mediterranean, the North Sea, and above the Arctic Circle.“HII’s investment in advanced undersea autonomy is yielding promising returns, most notably in demonstrating to our customers how this technology can be integrated to support their evolving and critical mission needs,” HII President and CEO Chris Kastner said. “From mine

Most Coastal Arctic Infrastructure at Risk by 2100
coastlines will face damage because of coastal erosion; 45% will be affected by sea level rise; and 77% of the Arctic infrastructure potentially will sit on ground that is no longer frozen solid but crumbling and subsiding.“Many scientists monitor threats to the natural environment north of the Arctic Circle (66.33°N), but little attention has been paid to the human presence there,” said Annett Bartsch, the founder of the Earth research and development company b.geos, who directed the study. “The number of people living along the Arctic coasts is comparatively small, but these people

challenging for crewmembers of both Coast Guard and U.S. Navy ships,” said Shattuck. “The conditions faced by Coast Guardsmen on the Healy make it especially difficult to achieve healthy sleep. Icebreaking and isolation pose additional risks.”The journey will be north of the Arctic Circle for much of the scheduled voyage, and will conclude in Tromsø, Norway later this fall. Shattuck will be accompanied by the Defense Innovation Unit’s (DIU) Chief Medical Officer, U.S. Navy Cmdr. Niels Olson. DIU supplied much of the technology being used in the study, and Olson is
Barclays Rejects Arctic Drilling
for companies seeking to drill in the Arctic Refuge as well as other climate change threats.According to the British multinational investment bank and financial services company headquartered in London, arctic oil and gas refers to new exploration and extraction of oil and gas in the area within the Arctic Circle which is subject to sea ice, and includes the Arctic National Wildlife Refuge (ANWR) and the Coastal Plains.The ANWR is a particularly fragile and pristine ecosystem which is central to the livelihoods and culture of local indigenous peoples.Barclays Energy and Climate Change Statement said:
Autonomous Vehicle Maps the Arctic Seafloor
Far above the Arctic Circle, an autonomous surface vehicle set out to map the seafloor in an effort to improve nautical charts in areas where there is scarce data and vessel traffic is increasing.A team of engineers and students from the University of New Hampshire’s (UNH) Center for Coastal and Ocean Mapping, together with personnel from NOAA’s Office of Coast Survey, recently returned from an Arctic voyage that deployed an unmanned surface vehicle (USV) from the NOAA hydrographic ship Fairweather, a first from a NOAA vessel in the region.The Fairweather spends each summer surveying the
US Navy Submarines Surface in the Arctic Circle
A pair of U.S. Navy submarines recently surfaced in the Arctic Circle as part of multinational maritime exercise north of Alaska. Los Angeles-class fast attack submarine USS Hartford (SSN 768) and Seawolf-class fast attack submarine, USS Connecticut (SSN 22) surfaced in the Arctic Circle March 10 during the multinational maritime Ice Exercise (ICEX) 2018. Both submarines, as well the UK Royal Navy submarine HMS Trenchant (S91), are participating in the biennial exercise in the Arctic to train and validate the warfighting capabilities of submarines in extreme cold-water conditions
