Denudation rates and Holocene sediment storage dynamics inferred from in situ 14C concentrations in the Feshie basin, Scotland

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 4, 30 March 2025.
Inferred catchment‐averaged denudation rates in post‐glacial landscapes do not always reflect true ‘basin‐wide’ denudation rates, and instead represent a mixture of sediment sourced from paraglacial deposits and ‘background’ hillslopes. Our results highlight the role of the glacial legacy on landscape evolution.

The Distribution of Linear Virgae Across the Saturnian Moons

open access: yesGeophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Linear virgae are long (10–100s km), narrow (<5 km), and bright features, first found on the surface of Dione. On Dione, linear virgae run parallel to the equator and are found in the low‐to‐mid latitudes. Linear virgae are likely formed by a process that involves the emplacement of materials from an exogenic Chronocentric (Saturn centric), or

Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

open access: yesGeophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Cosmic Rays and the Askaryan Effect Reveal Subsurface Structure and Buried Ice on the Moon

open access: yesGeophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract We present the first full‐wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra‐high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, wide‐bandwidth, linearly‐polarized radio ...
