Seismic Evidence of Impact Breccia and Unlithified Sediments Under Hiawatha Glacier

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 7, July 2025.
Abstract Hiawatha Crater in northwest Greenland is one of only two putative impact craters under an ice sheet. Hiawatha therefore offers a rare proxy for understanding the interactions between active glacial dynamics and impact craters on other planetary bodies.

The First Firn Core From the Cordillera Darwin Icefield: Implications for Future Ice Core Research

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The Southern Hemisphere westerly winds (SHWWs) (45–65°S) are important regulators of the Southern Hemisphere climate. The scarcity of observational records at the core of the wind belt hinders our understanding of the environmental impact and long‐term variability of the westerly winds.

Climate Feedbacks Derived From Spatial Gradients in Recent Climatology

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract Climate feedbacks, including Planck, surface albedo, water vapor‐lapse rate (WVLR) and cloud feedbacks, determine how much surface temperatures will eventually warm to balance anthropogenic radiative forcing. Climate feedbacks remain difficult to constrain directly from temporal variation in observed surface warming and radiation budgets due ...
