Title: Observing Sea Ice from Space: What do Microwave Sensors Reveal About Surface Processes?Speaker: Dr. Aikaterini (Katia) Tavri, Brown UniversityAbstract: Microwave sensors enable continuous observation of the polar regions, operating day and night and through cloud cover when optical satellites are limited. They reveal how sea ice surface properties--such as roughness, snow cover, and melt ponds--govern the exchange of heat and momentum between the ocean and atmosphere. Yet the melt season remains a major challenge: thin ice and widespread ponding blur the distinction between young and old ice types, reducing the reliability of long-term climate records. In this study, we examine thermodynamically grown first-year and multi-year ice, within a landfast region in the Canadian Arctic Archipelago, where the same floes can be tracked from late winter through advanced melt without the complication of ice motion. Using multi-frequency and multi-polarization microwave observations, we show that shorter wavelengths are better capturing surface scattering as melt ponds first form, while longer wavelengths are sensitive to volumetric contrasts and perform better as ponds drain. These results demonstrate how microwave observations encode the physics of melt-season transitions, extend the period over which satellites can reliably monitor sea ice, and provide new opportunities to improve climate records and predictions of sea ice evolution

URI Department of Art and Art History presentsREVELATIONS! Education: Behind The Curtain – In Words and Images Exhibition September 15- December 11Join us for a reception and art conversations on September 17 4:30-7 in Lippitt Hall 401What is it like being in the classroom? What challenges do educator’s face? What restrictions are there preventing education from occurring? Are the requirements, expectations and limitations changing the way Educators function? What are the successes - giving students the opportunity to find their expressive voice?This exhibit will include the artwork and voices of a group of area educators from public, private and independent educational settings on all levels. The artist/educators will share their creative voices in various forms of expression as they also reflect on the challenges and celebrations they experience in and out of the classroom.Among the more than twenty artists are: Mary Jane Andreozzi, Deanna Camputaro, Ruth Clegg, Raff Diaz, Raphael Diaz, Tamara Diaz, Melanie Ducharme, Adam Ferbert, Susan Garland, Melissa Guillet, Catherine Davis-Hayes, Chris Kelley, Susan Kolenda, Jason Robert LaClair, Don Mays, Kerry Murphy, Sam Peck, Lisa Marie Ricci-Russo, Monique Rolle-Johnson, Jade Sisti, Janice Lee Strain, John Tedeschi, Katie Walck.On exhibit in URI Lippitt Hall (3rd & 4th floor), Green Hall and The Higgins Welcome CenterOpen To Monday – Friday 7:30-4:30, closed weekends and holidaysFor information: (401)286-4620/ spennell@uri.eduVisit URInvolved for complete event details.
