China’s research icebreaker Xuelong 2 began the first ice-station operation of China’s 16th Arctic expedition near 84°N in the central Arctic Ocean on August 9. The work followed the voyage’s initial ocean-station survey and was expected to continue for about two weeks.
The expedition is designed as an integrated observation campaign: researchers will measure conditions in the atmosphere, sea ice, upper ocean and ecosystem beneath the ice at the same time. That approach is intended to help scientists understand not only how Arctic sea ice is changing, but also how those changes interact with the surrounding ocean and ecological processes.

On August 9, Xuelong 2 began an approximately two week ice station survey near 84°N in the central Arctic Ocean. Researchers are combining ice core and snow sampling, drifting buoys, sea ice remote sensing, atmospheric profiling and under ice ocean observations.
What should I do next in practice?
The first station was set up on a roughly 1.5 meter thick floe in dense ice; the expedition also prepared polar bear prevention and emergency response measures for field teams.
Xuelong 2’s plan includes seven ice stations in the central Arctic Ocean:
Six short-duration stations
One long-duration station
The first station was established in a densely packed ice zone on a large, relatively flat floe approximately 1.5 meters thick. The vessel moved toward higher latitudes after completing the first stage of its ocean-station work on August 7.
The Xuelong 2 stations are also intended to work alongside sites surveyed by the research vessel Xuelong. Together, the stations can form a broader observation array for studying interactions among the central Arctic’s atmosphere, sea ice and ocean, as well as their links with the ecosystem.
More than 20 research tasks across the ice and water
The field program includes more than 20 projects and operational tasks. Reported methods include:
Deploying disposable ice-based drifting buoys
Sampling snow and ice cores
Collecting water beneath the sea ice
Using remote sensing to observe sea ice
Measuring atmospheric profiles
Conducting under-ice oceanographic and hydrographic observations
These methods capture different parts of the Arctic system. Ice cores and snow samples provide material for examining the structure and condition of the ice and its surface layer. Drifting buoys can continue collecting observations as they move with the ice, while remote sensing extends the view beyond the immediate station. Atmospheric and under-ice measurements add information about the conditions above and below the floe.
The scientific questions behind the survey
During the sea-ice melt season, the team plans to track changing parameters across four connected areas:
Atmosphere: conditions and profiles above the ice
Sea ice: the physical state and changing characteristics of the ice cover
Upper ocean: water conditions immediately below the ice
Under-ice ecology: biological and ecological processes beneath the floe
The central scientific goal is to gather data that can improve understanding of the Arctic Ocean’s rapid sea-ice changes and the mechanisms driving them. The observations are also intended to document ecosystem evolution as the physical environment changes.
Because the measurements span the atmosphere, ice, ocean and ecology, they can be analyzed as parts of one connected system rather than as isolated observations. That is important for investigating how melting sea ice affects ocean–atmosphere interactions and the habitat and processes beneath the ice.
Polar bears are a key field safety risk
Ice-station work brings risks including extreme cold and uneven or complicated ice-surface terrain. Reports identified polar bears as a major safety risk for researchers working on the floe. In response, the expedition team prepared dedicated bear-prevention and emergency-response plans and equipped the operation with multiple types of related deterrence equipment and emergency supplies.
The available reports describe the existence of those plans and supplies but do not provide a detailed list of the equipment or specific response tactics. The safety arrangements are therefore best understood as a documented operational precaution, not as a publicly detailed protocol.
Why the observations matter
Xuelong 2’s survey is valuable because it places measurements from several parts of the Arctic environment at linked ice stations during a period of active seasonal change. The resulting records are intended to support research into the causes and mechanisms of rapid sea-ice change and the associated evolution of the Arctic ecosystem.
In practical terms, the expedition is building a detailed snapshot of what is happening above, within and below the sea ice—and collecting observations that can help researchers connect those changes over time.
