In February 2024 a new Chinese building rose on Inexpressible Island, a wind-scoured rock in Terra Nova Bay on Antarctica’s Ross Sea coast. Qinling Station, China’s fifth Antarctic outpost, opened with a floor area of about 5,244 square metres, room for roughly eighty people in summer and thirty in winter, and a research brief that runs from atmosphere–ice–ocean interactions to space physics. It was not a ceremonial first step. By then China already ran coastal stations on King George Island and in Prydz Bay, inland camps on the East Antarctic ice sheet, an Arctic station at Ny-Ålesund in Svalbard, and two icebreaking research ships named Xue Long — “Snow Dragon” — that shuttle people, fuel and instruments between Shanghai and the ends of the Earth.
China’s polar programme is often described in the language of presence: how many stations, how many voyages, how far inland. Those numbers matter, and they have grown quickly. What matters more for science is what the programme has actually measured — ice cores and sediment cores, aurora images and ionospheric radar, penguin colonies and glacier mass balance, infrared starfields above Dome A. This article takes a factual look at China’s polar science network. It sets out the ships and stations as they stand in the mid-2020s, from the Xue Long icebreakers and the Antarctic stations from Great Wall to Qinling to the Arctic Yellow River Station, along with the recent expedition results that Chinese official sources and international partners have put on the record, and the places where claims still need careful reading. It sits alongside other huaxia.click pieces on the scale of Chinese science, from the Chinese Academy of Sciences to fusion machines and Chang’e-6’s lunar samples, but it does not retell those stories.
From Treaty Accession to a Station Network
China acceded to the Antarctic Treaty in 1983 and organised its first national Antarctic expedition the following year. Great Wall Station was established in 1985 on King George Island in the South Shetland Islands, a relatively accessible part of the Antarctic Peninsula region that already hosted several other national bases. Zhongshan Station followed in 1989 on the Larsemann Hills overlooking Prydz Bay, giving China a foothold on the East Antarctic coast opposite Australia’s Davis Station and India’s Bharati. Those two coastal bases remain the logistical spine of the programme: they receive ships, stage inland traverses, and host year-round or seasonal work in meteorology, oceanography, biology and upper-atmosphere physics.
The Polar Research Institute of China (PRIC), based in Shanghai, is the operational heart of the system. It runs the ships, manages the stations, and publishes much of the expedition reporting that reaches the English-speaking press through Xinhua and the Ministry of Natural Resources. China is also a member of the Scientific Committee on Antarctic Research (SCAR) and of the Council of Managers of National Antarctic Programs (COMNAP), the two main international forums that coordinate Antarctic science and logistics. Those memberships do not settle every dispute about access or environmental impact, but they place Chinese polar work inside the same reporting and peer structures used by other treaty parties.
Arctic activity came later. Yellow River Station opened at Ny-Ålesund on Spitsbergen on 28 July 2004 — China’s first Arctic research station, at about 78°55′N, 11°56′E. Ny-Ålesund is an international research village under Norwegian sovereignty, not a Chinese enclave; Chinese teams work there under the same local rules as other nations. In 2018 China and Iceland opened a joint Arctic science observatory, extending the Arctic footprint beyond Svalbard. Ship-based Arctic cruises by Xue Long and Xue Long 2 have surveyed the Chukchi Sea, the Canada Basin and the central Arctic Ocean. Official Chinese tallies by 2025 speak of more than forty Antarctic expeditions and more than a dozen Arctic ones; those cumulative counts are useful as a sense of scale, but they mix voyages of very different length and scientific weight, so they should not be read as a simple productivity league table.
Xue Long and Xue Long 2
The first Xue Long began life as a Ukrainian-built ice-strengthened cargo vessel completed in 1993 and converted for polar research and resupply. At about 167 metres long, with a beam of roughly 22.6 metres and a full-load displacement often cited near 21,000 tonnes, she is large for a research ship. Her ice class is given by the China Classification Society as B1*, commonly treated as roughly Polar Class 6 in international terms — enough to operate in first-year ice with some multi-year inclusions, not enough to force a path through the heaviest Arctic multi-year pack the way a nuclear icebreaker can. For three decades she has been the workhorse that delivers fuel and building materials to Great Wall and Zhongshan, carries scientists into the Ross and Amundsen Seas, and, when needed, has taken part in high-profile rescues and evacuations that put her name into world headlines.
Xue Long 2, delivered from Jiangnan Shipyard in Shanghai in 2019 after a design partnership with Finland’s Aker Arctic, is China’s first domestically built polar research icebreaker. She is shorter than her sister — about 122.5 metres long, 22.3 metres in beam, with a full-load draft near 8.3 metres and a displacement of about 14,300 tonnes — but she is a more modern ice ship. Her diesel-electric plant drives two ABB Azipod units of 7.5 megawatts each. In open water she makes about 15 knots; in ice she is rated to break 1.5 metres of ice (plus about 0.2 metres of snow) at two to three knots, ahead or astern — a dual-acting hull form that matters when a ship must back and ram or reverse out of a pressure ridge. Her ice class is Polar Class 3. She carries laboratories, a moon pool for instruments, deck cranes, and a hangar and helideck. Complement is about ninety crew and scientists.
Together the two ships let China run overlapping Antarctic legs and Arctic cruises in the same season. The 40th Antarctic expedition (2023–24) was supported by Xue Long, Xue Long 2 and a cargo vessel, Tianhui, with a reported combined voyage distance of about 81,000 nautical miles — a figure from Chinese official summaries that is useful as an order of magnitude for a three-ship season, not as a precise scientific output metric. The 41st expedition (2024–25) again used three hulls in stages: Xue Long left Guangzhou on 1 November 2024 and returned in April 2025 after about 159 days and 27,000-plus nautical miles; a commercial support ship, Yongsheng, ran a shorter cargo leg; Xue Long 2 stayed out longer on Ross Sea work, with Chinese reports giving a voyage of about 208 days and more than 40,000 nautical miles before her return to Haikou at the end of May 2025. Expedition headcounts in the same reporting — on the order of five hundred people from more than a hundred institutions — mix ship crews, station staff, visiting scientists and engineers, so they describe the logistics envelope more than the number of principal investigators.
Great Wall, Zhongshan and the Coastal Bases
Great Wall Station sits on the Fildes Peninsula of King George Island, a few kilometres from Maxwell Bay, where icebreakers unload. Photographs of the station show a practical Antarctic campus: rectangular accommodation and laboratory blocks, often on raised foundations against snow drift; storage containers; fuel tanks; and white geodesic radomes for satellite and upper-atmosphere instruments. The surrounding terrain mixes snow, dark volcanic rock and low hills. Because King George Island is crowded with national programmes and accessible by ship for much of the summer, Great Wall has been a training and monitoring platform as much as a deep-field launch point — meteorology, coastal ecology, and the kind of long time-series that stations produce when they simply stay put year after year.
Zhongshan Station, on the Larsemann Hills, faces a different geography. Prydz Bay and the Amery Ice Shelf region are gateways to the East Antarctic ice sheet. From Zhongshan, Chinese inland teams stage the long tractor traverses that reach Taishan and Kunlun. The station supports ocean work in Prydz Bay, coastal ecology, and a growing suite of space-physics instruments. Chinese and international papers describe digisondes, all-sky imagers, magnetometers, imaging riometers and, later, HF radar and GPS scintillation receivers — the hardware of high-latitude ionospheric and auroral science. Zhongshan’s latitude also places it under the auroral oval in ways that pair naturally with Arctic observations from Yellow River Station, a geomagnetic conjugacy that Chinese upper-atmosphere groups have exploited for decades.
Neither coastal station is glamorous in the way a Dome A camp is glamorous. Their value is continuity. Ships come and go; a wintering crew keeps the generators running, the radomes pointed, and the sample freezers cold. When Chinese official releases talk about “five seas and five stations” surveys — peninsula waters, Cosmonauts Sea, Amundsen Sea, Prydz Bay, Ross Sea, matched to the station network — they are describing a coastal-and-ocean sampling grid that only works if Great Wall and Zhongshan remain reliable ports of call.
Kunlun, Taishan and the Ice Sheet Interior
Kunlun Station, opened in early 2009 at Dome Argus (Dome A), sits near the highest point of the East Antarctic ice sheet, more than a thousand kilometres inland from Zhongshan. Chinese and international site-testing literature has long argued that Dome A offers exceptional astronomical conditions: a high, cold, dry plateau with a thin turbulent boundary layer and long polar nights. The station itself has often been operated with only brief summer occupation; instruments then run with remote supervision through the dark months. That operating model is harsh on hardware. Temperatures, power, and communications all fail more easily than at the coast.
Even so, Chinese astronomy groups have treated Kunlun as a serious observing site. Earlier deployments included the Chinese Small Telescope Array (CSTAR) and Antarctic Survey Telescopes (AST3). During the 40th expedition, teams reported installing and servicing near-infrared instruments, low-frequency radio experiments and site-monitoring towers, and recovering a year of sky-brightness data from a near-infrared binocular telescope. In 2024–25, Chinese academy institutes described successful daytime stellar observations and polar-night monitoring with that near-infrared system alongside AST3-2. These are real engineering and observing milestones. What they are not, yet, is a finished infrared survey of the southern sky on the scale of the great temperate observatories. Dome A remains a hard place to keep a telescope alive; every polar-night data set is also a survival story for the instrument.
Taishan Station, established in 2014 on Princess Elizabeth Land, functions as a mid-route relay and summer research camp between Zhongshan and Kunlun — roughly a logistics and science waypoint on the inland traverse. Chinese reporting also mentions Grove Mountains work and, on recent expeditions, airborne surveys filling in ice-sheet data between the Zhongshan skiway and regions such as Enderby Land, the Grove Mountains, the Prince Charles Mountains and Princess Elizabeth Land. Those aerial campaigns matter because East Antarctica’s ice thickness, accumulation and bedrock topography still contain large blank spots in public datasets. Filling them is unglamorous cartography, but it is the kind of work that later ice-sheet models depend on.
Qinling Station and a Third Wintering Base
Qinling Station’s opening on 7 February 2024 gave China a Pacific-facing Antarctic presence on Inexpressible Island in Terra Nova Bay. Official descriptions emphasise a Southern Cross–inspired building plan, year-round capacity, and research themes that fit the Ross Sea: ice-shelf–ocean interaction, ecosystems, and space and geological measurements. The Ross Sea is already one of the most heavily studied sectors of Antarctica, with long-running American, Italian, Korean and other programmes nearby. A new Chinese station does not invent Ross Sea science; it adds berths, labs and a wintering platform under Chinese logistics.
The 41st expedition’s most concrete Qinling claims, as summarised by the Ministry of Natural Resources and carried by Chinese state media in April–July 2025, are logistical and engineering ones. Supporting infrastructure was completed. A wind–solar–hydrogen–storage energy system was applied at a Chinese Antarctic station for the first time, with official reports claiming renewable utilisation above sixty per cent — a figure that should be read as an operational claim from the programme itself, pending independent energy audits. Qinling mounted its first wintering, and China wintered at three Antarctic stations at once for the first time. In polar programmes, the ability to keep three crews alive through the dark months is a harder test than a summer opening ceremony.
Science results attributed to the same season include an Amundsen Sea sediment core of about 8.67 metres from a long gravity corer — useful for palaeoceanography if the core is well dated and shared — and a subsurface mooring record said to span 1,407 days, described as China’s longest polar mooring series to date. Multinational Ross Sea work in the autumn freeze-up was highlighted as a first for Chinese-led seasonal ecosystem sampling in that window. As always with expedition press releases, the core lengths and day counts are easier to verify than the interpretive phrases that follow them. The measurements are the achievement; the global-significance language around them is a claim to be tested in the journals.
Yellow River Station in the High Arctic
Yellow River Station is a different kind of place from Kunlun. Ny-Ålesund is a shared international settlement with harbour access, overlapping national stations, and Norwegian environmental rules that constrain everything from fuel handling to wildlife disturbance. China’s station there supports marine and terrestrial ecology, glaciology, atmospheric chemistry and space physics. Chinese review papers describe long-term Kongsfjorden marine sections and tundra plots, work on pollutants and heavy metals in plants, and microbial surveys that have reported new Arctic taxa — figures such as three new genera and twenty-one new species appear in Chinese ecological summaries and should be checked against the primary taxonomic publications before being repeated as settled biodiversity tallies.
Space physics has been a consistent strength. Yellow River Station’s long polar night suits auroral optical work. Chinese groups have run multi-wavelength all-sky imagers and riometers there, and have treated the station as a Northern Hemisphere counterpart to Zhongshan for conjugacy studies. In April 2024, Chinese and Xinhua reporting said seasonal research teams were again cycling through the station after pandemic disruption, with more than fifty researchers expected across the year and joint pollutant work with Norwegian scientists. Separately, ship expeditions and the China–Iceland observatory widen the Arctic portfolio beyond a single Spitsbergen building. China’s 2018 Arctic policy white paper framed the region in terms of scientific expedition, climate, and shipping — language that Western analysts often read through a strategic lens. The station’s day-to-day output, however, is still the stuff of ecology transects and aurora cameras.
What the Science Programmes Have Achieved
Strip away the anniversary rhetoric that marked forty years of Chinese polar expeditions in 2024, and a few research lines stand out as substantive.
First, ice-sheet and ocean observing. Inland traverses, airborne ice surveys, Prydz Bay and Amundsen–Ross ocean sections, and sediment and ice sampling have moved China from a coastal visitor to a contributor of primary Antarctic geophysical data. The Amundsen Sea core and multi-year mooring records from recent seasons are examples of the sort of datasets other programmes recognise. Second, upper-atmosphere and space physics: the Zhongshan–Yellow River conjugacy work, digisonde and all-sky networks, and GPS scintillation studies are long-running instrumental programmes, not one-off publicity cruises. Third, astronomy at Dome A: Chinese teams have spent two decades proving that robotic and summer-serviced telescopes can survive there and produce infrared and optical time-series. The scientific return is still maturing, but the site-testing and engineering papers are part of the international Antarctic astronomy literature. Fourth, ecology and environmental monitoring: Great Wall and Zhongshan coastal biology, Yellow River’s Kongsfjorden and tundra work, and Ross Sea ecosystem cruises sit inside SCAR and local management frameworks even when national press releases cast them as solo triumphs.
International cooperation is not an afterthought in the official narrative of the 41st expedition. Chinese releases mention multi-country Ross Sea autumn work, participation in circum-Antarctic “ring” action plans, a China–Russia drilling project, and BRICS-linked cruise cooperation. COMNAP and SCAR structures already assume that Antarctic logistics are shared — runway access, weather forecasting, search and rescue. Polar science that cannot be checked by others has limited value; data policies and sample sharing will decide how much of China’s growing field effort enters the global literature rather than remaining in national repositories. Chinese regulations on polar data management have been tightening on paper; practice will show in citation rates and open archives.
Capacity Claims and Contested Figures
Several numbers that travel with the Chinese polar story deserve flags. Expedition person-counts in the hundreds combine many roles and should not be compared directly with the scientist headcounts of smaller national programmes. Multi-ship nautical-mile totals measure steaming, not papers. Renewable-energy “utilisation” percentages at Qinling come from programme reporting. Biodiversity discovery counts need primary taxonomic sources. Icebreaking thicknesses are design ratings under defined snow and speed conditions, not guarantees in ridged multi-year ice. Station “fifth” or “sixth” numbering sometimes blurs summer camps, unmanned sites and year-round bases — Taishan’s status as camp versus station is a case where English summaries disagree in emphasis even when they describe the same place.
Geopolitical commentary, especially in Washington and Canberra, often treats every new Chinese Antarctic building as dual-use infrastructure. The Antarctic Treaty System bans military measures and requires peaceful purposes; it does not ban dual-use technologies any more than it banned GPS or satellite communications at other nations’ bases. Ground stations, icebreakers and wintering capacity have obvious strategic as well as scientific value. That dual reading is real. It does not, by itself, invalidate the glaciology or the aurora cameras. The honest approach is to keep both facts in view: China is building polar capacity at speed, and a growing fraction of that capacity produces publishable Earth-system science.
How the Polar Programme Fits Chinese Science
Polar research is expensive logistics wrapped around relatively small science teams. In that sense it resembles other Chinese big-science bets that huaxia.click has covered: the FAST radio telescope needed a sinkhole and a standing army of engineers before it could find pulsars; fusion devices in Hefei and Chengdu need years of magnets and vacuum vessels before a plasma shot means anything. The polar programme’s distinctive feature is distance. A broken generator at Kunlun cannot be fixed by a same-day courier. An ice season that closes early can strand a year’s inland plan. Xue Long 2’s dual-acting hull and Qinling’s hybrid power plant are answers to those failure modes as much as they are prestige objects.
Institutionally, PRIC and the Ministry of Natural Resources sit closer to survey and marine agencies than to the Chinese Academy of Sciences campus culture described in our Academy article, though academy institutes — especially in astronomy and atmospheric physics — supply many of the instruments and co-authors. Universities send students and principal investigators on seasonal berths. The result is a hybrid: a logistics organisation that can put three ships into the Southern Ocean, paired with research groups that publish in glaciology, space physics and ecology journals. For readers tracking China’s wider science rise, the polar programme is less like a single “Apollo moment” and more like a steadily thickening observing network — coastal, inland, Arctic and shipborne — whose value compounds with every wintering season that does not fail.
Conclusion
Forty years after the first Chinese Antarctic expedition, the programme’s outline is clear. Two icebreakers, a ring of Antarctic stations from King George Island to Dome A and Terra Nova Bay, an Arctic foothold at Ny-Ålesund, and a tempo of multi-ship summer operations that would have been unthinkable for Beijing in the 1980s. Qinling’s first winter and the recent Amundsen and Ross Sea field seasons show the system doing what polar systems are built to do: keep people and instruments working at the edge of the map long enough to bring home cores, mooring records and sky surveys.
The unfinished business is also clear. Inland astronomy still fights the cold. Data openness will decide international trust. Strategic suspicion will not vanish because a sediment core is 8.67 metres long. None of that erases the concrete record — Xue Long and Xue Long 2 on station, Great Wall and Zhongshan keeping the coastal clocks running, Kunlun and Taishan stitching the ice sheet to the coast, Yellow River watching the Arctic sky, Qinling lighting a third Antarctic winter. That is the polar programme as it exists now: less a mystery than a set of ships, buildings and instruments, and the measurements they have managed to return.
