South Korea’s Korea Polar Research Institute (KOPRI) has dispatched its research icebreaker Both on the country’s 17th Arctic expedition, with this year’s mission placing renewed emphasis on gathering scientific data that could support the future development of Arctic shipping routes as Seoul steps up preparations to capitalize on emerging northern sea lanes.
The 7,500-ton Both departed Incheon on Friday for a roughly three-month expedition that will conduct climate, oceanographic and ecosystem research across the Arctic while expanding observations of sea ice and navigation conditions relevant to commercial shipping, according to KOPRI.
The institute said researchers will collect data from waters around Alaska and the Chukchi and Beaufort seas, deploying autonomous observation equipment and carrying out studies on changing sea ice conditions, marine ecosystems, and the impacts of climate change. The expedition also includes work aimed at improving understanding of Arctic marine environments as shipping activity gradually expands during increasingly longer ice-free seasons.
“This expedition is a meaningful one that documents the Arctic, the front line of climate change, while simultaneously preparing for the era of the Arctic shipping route,” KOPRI President Shin Hyeong-cheol said in a statement.
“I hope that the field data secured by the Both will serve as a solid foundation to enhance Korea’s Arctic scientific capabilities and utilization value.”
The voyage comes as South Korea increasingly frames polar research alongside broader economic and maritime ambitions. The government is preparing to dispatch the country’s first trial container shipping voyage between South Korea and Europe via the Arctic later this summer, part of a wider strategy to evaluate whether the Northern Sea Route could eventually shorten transit times between Northeast Asia and European markets during seasonal navigation windows.
Seoul sees growing strategic value in developing the scientific expertise needed to support future navigation, even as Arctic routes remain constrained by unpredictable ice conditions, limited infrastructure, high insurance costs and geopolitical tensions.
South Korea is also positioning its globally competitive shipbuilding industry to benefit from rising demand for ice-class vessels as Arctic activity expands. In April, HD Hyundai Heavy Industries secured a $348.9 million contract to build Sweden’s next-generation icebreaker, marking the first overseas icebreaker order won by a South Korean shipbuilder. The vessel is scheduled for delivery in 2029.
At home, South Korea is pressing ahead with construction of its own next-generation heavy icebreaking research vessel. Hanwha Ocean was awarded the contract in 2025, with the new ship expected to enter service around 2030, substantially expanding the country’s polar research capabilities beyond those of the Bothwhich entered service in 2009. The project forms part of Seoul’s long-term strategy to strengthen Arctic science while supporting future shipping, resource and industrial opportunities in the polar regions.
South Korea’s political leadership aims to combine scientific research, advanced shipbuilding expertise and maritime logistics into a broader strategy aimed at establishing itself as a leading hub for the emerging Arctic shipping economy.
