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?

Establishment of a Purge and Trap Continuous‐Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ15N and δ18O) in Water Samples by Ti(III) Reduction

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Reframing anaerobic digestion as a defossilization platform

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Anaerobic digestion (AD) coupled with carbon capture, utilization, and/or storage (CCUS) is a deployable bioenergy platform that supplies renewable energy and bioresources while valorizing biogenic CO2 for integrated carbon management on the pathway to net‐zero.

Wallace's pARCs—Making Climate, Climate Change and Biodiversity Data Available to Protected Area Managers and Conservation Planners With an Example From Biebrza National Park, Poland

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
A spatial representation of the potential ‘adaptation effort’ that might be needed to maintain at least 75% of the species modelled in Biebrza National Park, Poland (white outline), at 1.5°C. The darker the green shading, the less adaptation would be needed.
