The Polar Geospatial Center at the University of Minnesota provides access to historical and new digital elevation models of polar regions
The National Geospatial-Intelligence Agency, National Reconnaissance Office and National Science Foundation have finalized an agreement to provide continued public access to historical and new digital elevation models created using commercial imagery collected over the Arctic and Antarctic. The agreement also allows NGA to share the imagery with NSF-funded university partners in order to update NSF’s ArcticDEM and Reference Elevation Model of Antarctica projects for the full 10-year duration of the contract, currently scheduled to end in 2032. The DEMs will also be publicly available on NGA’s  through ESRI’s ArcGIS platform and via NSF’s  at the University of Minnesota, enabling a wide variety of GIS, remote sensing, climate and mapping research use cases across the polar science community.

DSI affiliate Stevie Chancellor and grad student Ashlee Milton study TikTok's effects on mental health
The study is designed to pinpoint the true effects the one-of-a-kind social media platform has on its viewers. While many enjoy TikTok’s ability to produce fun, creative content, others are skeptical of its harmful effects on the viewers’ mental health. “TikTok is misunderstood by people who don't use the platform,” Chancellor said. “Our research shows that TikTok helps people find community and mental health information. But, people should also be mindful of its algorithm, how it works, and when the system is providing them things that are harmful to their wellbeing.” UMN CS&E,  paper pdf
