Groundbreaking Debut from UAE's Polar Research Hub
The United Arab Emirates has taken a significant step forward in global polar science with the release of the first peer-reviewed publication from the Polar Research Center at Khalifa University. The study examines how Antarctic sea ice and overlying snow layers react differently during sudden, extreme temperature increases, offering fresh insights into processes that influence ice stability and sea-level projections.
Published in June 2026, the research documents a rare atmospheric event in East Antarctica where temperatures rose by 18 degrees Celsius within a single day. This rapid warming episode, recorded in July, highlighted distinct behaviors between the ice itself and the snow cover, challenging assumptions embedded in many current climate simulations.
Establishing UAE Presence in Polar Research
The Polar Research Center operates as a key initiative under the Emirates Polar Program, an effort supported by the UAE government to contribute meaningfully to understanding the cryosphere. Hosted at Khalifa University, the center focuses on polar climate, meteorology, the cryosphere, oceanography, and biogeochemistry. Its establishment reflects the country's commitment to addressing knowledge gaps in regions undergoing rapid environmental shifts.
Khalifa University researchers have already deployed instruments on the Antarctic continent, marking the first such operational contributions from any UAE institution. These efforts align with broader national priorities in climate science and international scientific collaboration.
The July Storm Event and Data Collection
Central to the study was the deployment of a Snow Ice Mass Balance Array, known as SIMBA, on fast ice roughly 1.8 kilometers offshore from Mawson Station in East Antarctica. Placed seven days prior to the storm, the five-meter instrument, equipped with hundreds of sensors, began continuous hourly measurements of temperature, ice thickness, and snow depth.
The storm originated as a mass of warm, moist air from the subtropics and swept across the Southern Ocean. It produced wind speeds exceeding 30 meters per second at the site, with atmospheric modeling indicating peaks above 45 meters per second in collision zones between incoming warm air and cold plateau drainage winds. Precipitation rates along the coast reached more than three millimeters per hour during the event.
Distinct Responses of Sea Ice and Snow
Measurements revealed that sea ice followed a steady seasonal thickening pattern, reaching a maximum of 1.16 meters in late October before thinning to six centimeters by the end of November. In contrast, snow depth proved highly variable, with changes of up to eight centimeters occurring in a single day due to wind, storms, and temperature shifts.
During the July temperature spike, strong winds scoured the snow layer, preventing accumulation. Subsequent warm, dry air descending from the Antarctic Plateau further reduced remaining snow cover. The underlying sea ice, however, showed minimal immediate response to the same conditions. This divergence underscores how snow and ice layers operate under different physical drivers, a nuance often underrepresented in large-scale models.

Implications for Climate Models and Sea-Level Rise
Accurate representation of these differential responses is essential for refining projections of Antarctic ice loss and associated global sea-level changes. The study demonstrates that extreme weather events can rapidly alter snow distribution while leaving ice thickness relatively stable in the short term, information that helps close gaps in predictive capabilities.
Researchers note that sustained, year-round observations will be required to capture full seasonal cycles, including summer melt periods, and to develop statistically robust datasets for model improvement.
International Collaboration and Leadership
The work was led by Dr. Diana Francis, Head of the Environmental and Geophysical Sciences Lab and Assistant Professor of Earth Sciences at Khalifa University. Co-authors included scientists from the Australian Antarctic Division, the University of Tasmania, ETH Zurich, the University of Porto, and the Swiss Federal Institute for Forest, Snow and Landscape Research.
Such partnerships strengthen the UAE's integration into the global polar research community while bringing local expertise to bear on pressing questions about cryospheric change.
Future Directions for the Polar Research Center
Building on this initial publication, the center continues to expand its observational network and participation in expeditions. Faculty members from Khalifa University have been invited to join the 2026/2027 season at a New Zealand Antarctic research station, further enhancing data collection and cross-institutional ties.
Ongoing work emphasizes the connections between polar processes and broader climate dynamics, including potential influences on weather patterns far from the poles.
Contribution to UAE Higher Education and Research Capacity
The Polar Research Center provides valuable opportunities for graduate students and early-career researchers at Khalifa University to engage in high-impact fieldwork and analysis. These experiences support the development of specialized expertise in Earth sciences, atmospheric research, and climate modeling within the UAE academic landscape.
By hosting such initiatives, Khalifa University reinforces its role as a hub for advanced scientific inquiry aligned with national development goals in sustainability and knowledge-based economy sectors.

Context Within Global Polar Science
Antarctic research has gained urgency as temperature anomalies and ice-extent variations become more pronounced. The UAE's entry into this field through targeted instrumentation and collaborative publications adds valuable ground-truth data from underrepresented sectors of the continent, particularly East Antarctica.
The center's focus on continuous, in-situ measurements complements satellite and modeling efforts, contributing to a more complete picture of how extreme events interact with the ice system.
Looking Ahead: Sustained Observation and Model Refinement
Longer-term deployments spanning full annual cycles will enable researchers to quantify the frequency and cumulative effects of temperature spikes. This expanded dataset is expected to inform updates to climate models used by international bodies assessing sea-level rise scenarios.
The success of the initial SIMBA deployment demonstrates the feasibility of UAE-led contributions to polar fieldwork and sets the stage for expanded programs in coming seasons.
