Genetics in the Ocean's Twilight Zone: Population Structure of the Silvery Lightfish Across Its Distribution Range

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

Nonstationary Flood Frequency Analysis Using Reconstructing Past Millennium Floods Based on Large‐Scale Climate Indices

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT With global climate change and human activities, environmental uncertainties are increasing, and extreme flood events are occurring more frequently. The reliability of traditional hydrological frequency analysis theories, based on the assumption of stationarity, is being increasingly questioned.

Pacing Early Mars Sedimentary Rock Formation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Mars' sedimentary rock record documents past surface and/or near‐surface liquid water. However, paleoclimate models struggle to explain conditions warm enough for past liquid water. One hypothesis is transient warming by H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2}$ collision‐induced absorption (CIA) (H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2 ...

Freeze‐Thaw Cycling Accelerated Olivine Weathering and Water Sequestration on Icy Mars

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Geological evidence and paleoclimate models suggest that freeze‐thaw (FT) cycling has played a pivotal role in shaping the Martian surface composition throughout geological time. Here we show the experimental investigation of the sulfuric acid weathering of olivine under simulated FT conditions (193–293 K).

Preferred Time Scales of Pacific Decadal Variability During the Last Millennium Related to Volcanic Activity

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pacific Decadal Variability (PDV) plays a significant role in modulating the global climate change on decadal time scale. Although various reconstructions of the PDV have been developed for the last millennium, preferred time scales of the PDV and mechanisms behind them remain unresolved. Here, we combine a δ18O‐based PDV index derived through

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

Intensification of Northern Hemisphere Glaciation Triggered the Red Clay to Loess‐Paleosol Shift on the Chinese Loess Plateau 2.7 Million Years Ago

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate. However, the timing and associated mechanisms of red clay to loess‐paleosol shift remain debated.

Glacier Equilibrium‐Line Altitude Change Across Alaska and Adjacent Canada Indicates a Cold, Dry Little Ice Age and Weaker Aleutian Low

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract As Arctic warming accelerates, understanding hydroclimate shifts is key to projecting glacier melt and sea‐level rise. We assess the climatic signature of the Little Ice Age (LIA; ∼1250 to 1900) by quantifying changes in equilibrium‐line altitude (ΔELA) for 215 Alaskan glaciers from the LIA maximum to present (2016–2024), using remote sensing ...
