The Sporadic Fluvial Regime of Pliva Vallis, the Outlet Valley of Jezero Crater Lake, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract In situ and orbital observations have suggested that Jezero crater (field site for the Mars 2020 Perseverance rover) once hosted a paleolake fed by two inlet valleys. An outlet valley, Pliva Vallis, is present on the eastern rim of the crater and raises the question of whether the lake system operated as an open basin or as a closed basin ...

A Model for Regional‐Scale Water Erosion and Sediment Transport and Its Application to the Yellow River Basin

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract On catchment scales, sediment discharge depends on both sediment transport capacity and sediment availability. The quantification of sediment discharge at the regional scales is important but is rarely adequately represented in regional hydrological models.

Bridging Gaps in Satellite Observations of River and Delta Landscapes Using Image Warping

open access: yesWater Resources Research, Volume 61, Issue 5, May 2025.
Abstract Satellite images are increasingly used to monitor changes in fluvial landscapes such as channel migration, bar development, and avulsion. Yet, spatial and temporal gaps in image data — due to intervals between observations, cloud cover, or sensor malfunctions — limit their applicability.

Identification of Natural Hydrogen Seeps: Leveraging AI for Automated Classification of Sub‐Circular Depressions

open access: yesEarth and Space Science, Volume 12, Issue 5, May 2025.
Abstract Hydrogen has long been used as an energy vector, but the recent discovery of natural hydrogen (H2) opens the door for its use as a direct energy source. Identifying H2 seepages is therefore crucial to advance exploration. Although the scientific community does not yet fully understand the parameters controlling H2 leaks from underground, sub ...

Desktop Method to Map and Assess Environmental Impacts of Formal and Informal Mountain Biking Trails in an Urban National Park

open access: yesEcological Management &Restoration, Volume 26, Issue 2, May 2025.
ABSTRACT Recreational trails, including informal trails created by visitors, have a range of ecological impacts, but mapping and assessing these impacts can be expensive and time‐consuming. It is increasingly possible to harness publicly available data posted by park visitors to fitness platforms and combine it with other spatial and field data to help
