Jan 2026 Next Practices for Collaborative Research
For the NNA UtqiaġvikSensor Array project, Co-PI Caitlin Wylie and postdoc Hannah Bradley have focused their social science research on observing and analyzing the developing collaboration between our academic colleagues and our community partners, asking “How can scientists and communities best work toward common goals?”

Sept-Oct 2025 Fall 2025 Research Studio The second year of City Built on Thawing Ground, a traveling research studio led by Leena Cho and Matthew Jull, examined how permafrost thaw, snow redistribution, and surface water processes are impacted by the built environment. Building on existing study sites in Utqiaġvik, students combined site documentation and targeted thaw probing with interpretation of sensor data to map surface conditions to support planning and design work at parcel and neighborhood scales.

Snow and Ice: Tracking Infrastructure Impact in Arctic Aquatic Systems (Part II)
From 30 September to 7 October, Utqiaġvik, Alaska, greeted us with a surprise: about 3 inches of shorefast ice on our study sites. At the same time last year, these shores were only lightly iced even later in October, so this early, solid ice cover was not what we expected. Our targets were the same three water bodies, now in their early winter mode: Imikpuk Lake, Middle Salt Lagoon, and Isatkoak Lagoon. Keep reading

Water, water, everywhere: Tracking Infrastructure Impact in Arctic Aquatic Systems (Part I) For their summer sampling campaign, the aquatic team walked the shores of three of Utqiaġvik’s large water bodies to gather key water quality parameters that will help us understand the chemical signatures of seasonal rhythms, human activity, and permafrost dynamics.

Finding Air Quality Hotspots to Inform Dust MitigationAnother UVA|ARC team traveled to Utqiaġvik this spring to deploy “BigDot” particulate matter (PM) sensors in areas deemed to be potential or observed hotspots for dust, and therefore, for poor air quality. Eighteen sensors were deployed across the city. Keep reading

May 2025 Social Scientists go to the Field
In mid-May, social scientists Hannah Bradley and Cheri Johnson traveled to Utqiaġvik alongside our colleagues from the Environmental Science and Architecture departments to continue our social studies of how science works. Watching scientists do science is just one aspect of our research, and it's great to be in the field and lend a hand or hold a ladder. Our social science observations covered two aspects of our research...

Snow, Pixels, and Probes: Ground-Truthing in UtqiaġvikOver a week in May, the team
collected over 900 snow depth and density measurements spanning open tundra, built environments, and zones affected by wind redistribution in Utqiaġvik. Keep reading

Sensor Reset Maintaining the Utqiaġvik Sensor Array includes routine tasks like changing batteries and replacing sensors that have stopped communicating. We have also been working to make the network more robust. The UVA|ARC team is investigating what types and numbers of sensors to install to enhance the Utqiaġvik Sensor Array over the next year.
