The acidity of the Antarctic, or Southern, Ocean could double by the end of the century, finds a study led by INSTAAR Cara Nissen. This could have detrimental effects on the icy ecosystem’s smallest inhabitants, like plankton and krill, that are the base of the food web in the ocean.

A groundbreaking multi-year research initiative launched at Chico State in the aftermath of the Camp Fire examined the presence of contaminants, including metals, in nearby watersheds. Joined by researchers from CU Â鶹ӰԺ and the USGS, the research, recently published in the prestigious Journal of Environmental Science: Processes and Impacts, sheds light on the alarming impact of wildfires on stormwater runoff.

Listen to a 6-minute tour of the National Science Foundation’s Ice Core Facility (NSF-ICF) in Lakewood, Colorado. Facility staff will guide you through the world's largest frozen archive of ice, sharing some stories of ice drilling from the Arctic to Antarctica. Bruce Vaughn, co-founder of INSTAAR's Stable Isotope Lab, will show you how ice cores can record a long history of past climate and put the rapid postindustrial rise of CO2 in perspective.

Nikki Lovenduski is featured in this two-minute video, discussing how the Antarctic Ocean could become too acidic for many animals to survive by the end of the century without drastic measures to curb emissions from fossil fuels. She references a recent publication led by Cara Nissen and including herself and Cassandra Brooks as well as three colleagues from the Alfred Wegener Institute.

Tim Higgins, a PhD candidate in the department of Atmospheric and Oceanic Sciences, is investigating the impacts of climate change on atmospheric rivers and extreme precipitation events that affect the western United States. With his fellowship funds, Higgins traveled to the World Climate Research Program (WCRP) Open Science Conference in Kigali, Rwanda to present his research.

Thanks to the CU Museum of Natural History, the lobby of our SEEC building on East campus has a new guest: a full-sized skeletal reconstruction of a Triceratops dinosaur. The skeleton is a testament to the sheer size of Triceratops, an herbivore that roamed Colorado during the Cretaceous Period around 68 to 66 million years ago. Students, staff and members of the public can view the exhibit for free on weekdays from 7:30 a.m. to 5:30 p.m. (SEEC is closed on weekends and holidays).

The acidity of Antarctica’s coastal waters could double by the end of the century, threatening plankton and all marine life that inhabits the Southern Ocean, according to a new study published in Nature Communications. Cara Nissen is first author of the study. Coauthors include additional INSTAARs Nikki Lovenduski and Cassandra Brooks as well as three colleagues from the Alfred Wegener Institute.

Video interview with Noah Molotch about how remote sensing technology is helping forecast water availability in the Rocky Mountains. Watch this two-minute, well-edited interview, interspersed with clips of fieldwork and explanatory illustrations.

The 2023 winter brought record snowfall to California, but getting accurate snow depth data over a wide area is not easy. Read about the challenges of garnering snow data and the tools behind the data. Among the experts consulted is Karl Rittger (INSTAAR Fellow & NSIDC Affiliate), who leads the Snow Today project, visualizing and analyzing snow conditions across the Western U.S.
