Tyler Jones, Brad Markle, and Valerie Morris are leading a group of students in resampling the Greenland Ice Sheet Project Two (GISP2) core to investigate mechanisms of abrupt climate change and extreme events of the past. The original measurements (e.g., water isotopes) numbered a few thousand while the new measurements will create millions of data points.

For the second summer in a row, the CU Boulder Division of Public Safety's Flight Operations department is supporting important campus research in Alaska, as part of the Navigating the New Arctic project (principal investigator: Tyler Jones), which is being managed by researchers in the Stable Isotope Lab of INSTAAR.

Confronted with ever alarming impacts of climate change, longtime INSTAARite Bruce Vaughn has found hope and inspiration in the many bright minds who are working on solutions. Read his essay for the non-profit Arctic Arts Project, which seeks to educate and inspire through impactful imagery, backed by the most current science.

INSTAAR is pleased to announce that Sylvia Michel is the first recipient of its Outstanding PRA Award. This new award recognizes a professional research assistant (PRA) who has demonstrated excellence in their role and within the larger communities of INSTAAR and the University.

INSTAAR and the Dairy Arts Center collaborated on our second Art and Science Connections Collider on April 10th 2023 during Boulder Arts Week. The event began with a tour of INSTAAR’s Stable Isotope Lab (SIL) that included a look at actual ice cores from Antarctica and Greenland and a demonstration of how we analyze greenhouse gases in atmospheric samples. After the tour, the group had a general discussion in the Bartlett Science Communication Center.

The Far North is thawing, unleashing clouds of planet-heating gas. Tyler Jones, Bruce Vaughn, and Kevin Rozmiarek use detectors on drones or carried by hand to measure methane release from permafrost in Alaska.

Researchers from Imperial College London have performed new measurements using data from INSTAAR's Stable Isotope Lab (Sylvia Englund Michel). They found London produces 30-35% more methane than previously thought. Previous estimates suggested 25% of London's methane is from natural gas leaks, but the new study says it's up to 85%.

The sudden and sustained rise in atmospheric levels of the potent greenhouse gas methane since 2007 has posed one of the most significant and pressing questions in climate research: Where is it coming from? Now a research team has tested the leading theories for surging methane levels by analyzing the stable carbon isotope ratios (δ13C-CH4) from methane captured in a large set of global air samples to determine if one of the theories is more feasible than the others.

In INSTAAR's Stable Isotope Lab lie rows of metal flasks holding clues to the cause of an alarming rise in a powerful greenhouse gas. They contain samples of air from around the world that Sylvia Michel‘s team of methane detectives analyse to reveal whether the gas came from burning fossil fuels and wood, or from wetlands and cow guts.
