The Spectroscopic Impact of Sublimation Under Martian Surface Conditions: Implications for Sample Analysis by the Rosalind Franklin Rover and Biosignature Preservation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The 2028 ESA/NASA Rosalind Franklin Mission (RFM) will search for signs of past and present life in the shallow subsurface of Mars. It is crucial to understand how minerals and any biosignatures uncovered during these sampling activities might change and be identified under today's Martian conditions.

Seeing Through Geomorphic Complexity to Recover Tectonics From Topography: Inverting Landscapes for Uplift Histories Using the Wasserstein Distance

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract An important problem in the Earth sciences is extracting information about tectonic and other processes from topography. A general challenge is that geomorphic activity that we typically have little information about during the lifetime of a landscape can introduce geomorphic “noise”.

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Phenotypic and Genomic Signatures of Adaptation in Urban Populations of the Wild Radish Raphanus raphanistrum

open access: yesEvolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT By modifying biotic and abiotic environments, urbanisation can influence the evolutionary adaptation of organisms, especially when their distribution is fragmented. However, the effects of urbanisation on evolutionary adaptation remain poorly understood within a metapopulation framework, where high gene flow and recurrent extinctions ...

Ocean Bottom Seismometers Provide Direct Measurements of Pulsed‐Structure and Turbulence of Turbidity Currents Overspilling From a Submarine Channel

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Turbidity currents transport vast amounts of sediment, carbon, and heat along submarine channels, yet their overspill onto channel‐levees and abyssal mixing remain poorly constrained due to lack of direct observations. Ocean‐bottom seismometers (OBS) deployed on the Congo Canyon–Channel levees captured the structure and turbulence of overspill
