The Strategic Importance of Arctic Subsea Cables
International deep-sea submarine cable networks provide 99% of all global telecommunications. Arctic subsea cables have been a testament to this success, providing greater reliability and increased real-time data integration across vast distances, connecting continents like never before. Neatly put, the Arctic is a vital region for internet connectivity, gaining the attention of countries, providers, and other organizations involved in the telecommunications industry.
As such, currently laid and future-planned Arctic subsea cables are driven by rapid changes in the environment, geopolitical tensions, and technological advancements. Facing these factors simultaneously creates new opportunities and challenges for countries and corporations vying for control over these undersea networks.
Climate Change: Both a Challenge and a Catalyst
The Arctic is an unpredictable and harsh environment, making it a difficult place for long-term infrastructure projects. Seasonal ice flows, extreme weather conditions, and fragile ecosystems present operational hazards that can damage the cables or disrupt their installation. An unfortunate example of this was seen in Alaska when an undersea fiber optic line was ruptured by sheets of ice, causing mass telecom outages.
As such, the cost of laying cables in the Arctic is higher than in temperate regions due to the possibility of ice scraping against cables, unpredictable weather, and the difficulty of making repairs if a line is damaged. Nevertheless, companies and governments are pushing forward with their Arctic cable plans due to the region’s strategic value. And with the rise of global warming, it seems we’ve hit a bittersweet point in time for future Arctic subsea cables to be laid.
The Far North Fiber project is looking to utilize a current silver lining when it comes to global warming. Typically, thick, multiyear layers of ice make it nearly impossible to construct cable lines, but the rapid shrinking of ice layers during the summer months which used to not be commonplace, means there is a window of time to install the cables safely. These cables will then be protected for a significant part of the year once the ice returns in the colder season. Considering the amount of data and speeds Arctic subsea cables can maintain, companies and stakeholders alike agree the benefits of targeting this area for fiber optic growth outweigh the risks.
Geopolitical Tensions and Security Concerns
Arctic subsea cables have proven their strategic importance for global telecommunications, drawing the attention of major global powers. With massive amounts of data being shot across these fiber optic lines, countries are investing upwards of millions of dollars into the development and maintenance of subsea cables. One such country is Canada, working to install multiple Arctic subsea cables over the course of the next 10 years.
Some areas of the Arctic experience high traffic of commercial fishing and boating, adding potentially harmful equipment to the already abundant mix of possible environmental mishaps. This possibility was taken into consideration when damage to submarine cables occurred in the Nordic region – but it wasn’t the only possible cause.
The other side of the security coin is possible interference from countries with different geopolitical standings and allies.
Possible attacks are a high priority for governments to deter and mitigate, as cyber-attacks and physical disruptions of fiber-optic cables can affect both civilian and military communications. With many countries seeking to utilize the Arctic for their communications, it is imperative they also plan on the defensive to safehold Arctic subsea cables that are put in place.
Technological Advancements
All great technology comes with even greater advancements, which is why Arctic subsea cables are seeing pivotal developments and innovations. To start, as a first line of cable defense, a lot of research has gone into the development of more durable and resilient fiber optic cables as these cables must endure extreme temperatures, ice movement, and strong currents.
The use of Science Monitoring and Reliable Telecommunications (SMART) cables to collect Earth and oceanic data has also been demonstrated by research teams in North America, Asia, and Europe. These advanced cables integrate sensors with high bandwidth, showing great potential to be used in multi-hazard warning systems. Such advancements are not only beneficial to the telecommunications infrastructure but also to communities that fall within danger-prone areas.
Outside of the cables themselves, other technologies are being developed to build and improve these deep-sea networks. Autonomous underwater vehicles (AUVs) improve precision and reduce human risk in challenging environments, making them perfect for use in the laying and maintaining of cables in the Arctic. Advancements in sensor technology are also on the horizon, enabling real-time monitoring of cable conditions to spot potential threats.
These innovations, combined with improvements in data transmission capacity, are set to make Arctic subsea cables not only more resilient but also more efficient in delivering faster, higher bandwidth connections across continents.
Arctic Subsea Cables Are Not Solidified in Ice but in Our Telecom Infrastructure
Arctic subsea cables are an integral part of global communication infrastructure, strengthening internet connectivity and boosting the speed and capacity of global communications. They require strategic planning and creative, sustainable solutions to combat environmental and geopolitical threats. Yet, the benefits of these cables far outweigh the current obstacles, especially alongside technological advancements. With companies and countries investing in what was once considered an icy wasteland, the Arctic undoubtedly plays a crucial role in the shaping and further development of global communications.
