University of Houston scientists conduct climate research from Greenland to Antarctica

Thwaites Glacier in Antarctica and Kangerlussuaq in Greenland, despite being nearly 11,000 miles apart, are key sites for climate research conducted by the University of Houston. Professor Brandee Carlson from the UH College of Natural Sciences and Mathematics is leading studies at these locations to understand sediment discharge from melting glaciers and its impact on coastal land-loss due to sea level rise.

Carlson's team is examining how sediments affect delta growth patterns using field observations and satellite imagery. "Understanding where sediments are going is critical to protecting coastal communities around the world," says Carlson. The steady sea levels at Kangerlussuaq make it an ideal study location, contrasting with rising levels along the Gulf Coast that lead to erosion.

The research also involves students like Caroline Mandujano, who values the hands-on learning experience. "It really is the best classroom on Earth," she says.

In Antarctica, Professor Julia Wellner focuses on Thwaites Glacier, known as the "Doomsday Glacier" due to its rapid retreat contributing significantly to global sea level rise. Wellner's work through the Thwaites Offshore Research project aims to understand this glacier's stability better. "Knowing when this rapid retreat began helps us better understand the glacier’s stability," Wellner explains.

Ph.D. student Asmara Lehrmann examines Thwaites' sediment record to assess its impact on global sea levels. Despite challenges, Lehrmann finds inspiration in Antarctica's dynamic landscape.

Both Carlson and Wellner emphasize their commitment to applying their findings locally along Texas's Gulf Coast. "We are actively engaged in coastal research here in Texas," says Wellner, highlighting ongoing projects addressing regional sea-level rise issues.

The work of UH researchers extends globally, addressing climate challenges from Texas to polar regions. "That's the nature of being Earth scientists is that we’re out there literally studying the entire planet," concludes Wellner.
