Assessment of soil slurry saturation and slurry infiltration in pig slurry storage ponds using electrical resistivity tomography

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Effective management of pig slurry in semi‐arid settings is critical to protect soils and aquifers. This study integrates multi‐profile electrical resistivity tomography (ERT) compiled into stitched 3D volumes with a calibration based on modified Archie's law derived from laboratory resistivity–moisture tests to obtain semi‐quantitative soil ...

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Agrarian counterpoint

open access: yesAmerican Ethnologist, Volume 53, Issue 2, Page 171-182, May 2026.
Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

Seismic Stratigraphy and Tectonic Evolution of the Forearc Georgia Basin (Upper Cretaceous–Miocene), Canada and USA, With Implications for CO2 Sequestration

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
2D seismic and well data reveal multi‐phase basin filling in the Whatcom Sub‐Basin shaped by syn‐depositional tectonism. An Eocene transition from forearc basin to forearc depression corresponds to decreasing normal‐fault density and throw, both upsection and eastward. Paleogene–Neogene strata are the best CO2 storage targets.

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene‐Eocene Thermal Maximum at the Southern Iberian Margin

open access: yesGeobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT During the Paleocene‐Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). This climatic event caused a widespread ocean deoxygenation, leading to substantial biotic turnover.

The assessment of present, past and future climatic variability in the americas from tree-line environments [PDF]

open access: yes, 2001
In this note we introduce one of 14 Collaborative Research Networks (CRN) funded by the Inter-American Institute for Global Change Research. It was established in 1999 and involves 15 principal investigators from 13 institutions in Canada, USA, Mexico ...

Navigating Practical, Political, and Ethical Challenges of Long‐Term Human Biology Field Research: The Shuar Health and Life History Project

open access: yesAmerican Journal of Human Biology, Volume 38, Issue 4, April 2026.
ABSTRACT Major advances in understanding human biology and health have been made possible by long‐term field research projects with Indigenous peoples, whose ecological settings and lifeways are distinct from majority populations in high‐income settings.

Correlating magnetic fabrics with finite strain : comparing results from mudrocks in the Variscan and Appalachian Orogens [PDF]

open access: yes, 2004
New magnetic anisotropy data from Variscan mudstones collected in the Cantabrian Arc, N Spain constrain the corresponding strain (shortening). The results are based on our previous study of mudrocks from the Valley and Ridge Province (Appalachians) where

Diverse Seasonal Patterns of Precipitation and Terrestrial Water Storage Over the Indochina Peninsula: Roles of Monsoons, ENSO, and Topography

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
Warm ENSO phase events weaken Asian monsoons, reducing precipitation and TWS in northern and southern ICP, while central ICP's bowl‐shaped topography increases TWS. Seasonally, the Indian Monsoon brings abundant rainfall during May–September, which lags into TWS by 2 months.
