Overview on karst geology of Vietnam

open access: yesCarsologica Sinica
Karst is widely distributed in Vietnam, covering almost 60,000 km2, approximately 20% of the total area of Vietnam. Most karst rocks crop out in North and Central Vietnam. Karst developed with peak-clusters, peak-forests, caves, etc.

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Formation and evolution of the karst pastoral landscape in Puzhehei

open access: yesCarsologica Sinica
Traditional karstology examines karst geomorphic landscapes as geological processes occurring at the interface of lithosphere and hydrosphere. It concludes with a discussion on how factors such as structure, stratigraphy, hydrology, climatic conditions ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Simulation of Soil Water Content in Clayey Soils Where Dissolution and Precipitation of Pedogenic Carbonates Impact the Accuracy of Sensors Measuring Soil Water Content

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
This study deals with limitations of frequency domain reflectometry sensors, including data drift, when monitoring clayey soils with pedogenic carbonates. Despite these inaccuracies, the results demonstrate that corrected measurements of soil water content can still successfully calibrate hydrological models.

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...
