Flushing of Subsurface Soil Nitrate as the Primary Cause of Increased Stream Nitrate During Storm Events

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The export flux of nitrate from forested catchments via streams typically increases during storms due to simultaneous increases in the nitrate concentration and flow rate. Potential nitrate sources responsible for this increase include rainwater and soil nitrate.

Nitrogen Memoryscapes: Typologies of Nitrogen Inputs and Riverine Loads Across the Continental United States

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Nitrogen pollution has severely impacted inland and coastal waters, contributing to eutrophication, harmful algal blooms, and drinking water contamination. Reducing nitrogen inputs is widely expected to improve water quality, but watershed responses to changing nitrogen surplus are often nonlinear and delayed, complicating expectations of ...

Influence of Deep‐Sea Carbonate Sediments on the Long‐Term Durability of Carbon Storage From Ocean Alkalinity Enhancement

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Ocean Alkalinity Enhancement (OAE) is a marine carbon dioxide removal (CDR) strategy with a theoretical sequestration potential of several Gt CO2 ${\mathrm{C}\mathrm{O}}_{2}$ yr−1 ${\mathrm{y}\mathrm{r}}^{-1}$. The long‐term durability of OAE‐induced carbon storage depends on the persistence of the added alkalinity in the ocean, which is ...

Intensified Oxygen Minimum Zone in Response to Both Insolation Maxima and Carbon Dioxide‐Driven Warmth in the Tropical North Atlantic

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Oxygen (O2) is essential for almost all life on Earth, but O2 concentrations are rapidly declining in the oceans under global warming, stressing marine ecosystems and biogeochemical cycles. Numerical model simulations suggest greatly expanded North Atlantic Oxygen Minimum Zones (OMZs) under warm Pliocene conditions, but sparse data limit ...

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Nanopore Long‐Read Metagenomics Reveals Pollution‐Driven Antibiotic Resistance and Xenobiotic Degradation in Urban Beach Microbiomes

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Using nanopore metagenomics, this study reveals that anthropogenic pollution drives ecological and functional shifts in coastal microbiomes. Pristine island environments act as stable, Prochlorococcus‐dominated baselines, whereas urban beaches function as hotspots for opportunistic taxa, harbouring a robust genomic potential for xenobiotic degradation ...

Leveraging Microbes for Sustainable Development Goal 14 Progress

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Microbial systems can contribute to UN Sustainable Development Goal 14: Life Below Water efforts by transforming plastics, removing excess nitrogen, supporting coastal restoration and improving aquaculture sustainability. Advancing these applications requires field‐scale validation, ecological risk assessment and innovative deployment strategies ...

The Effects of Microplastics and Additives on Ecosystem Function, Structure, and Signaling

Global Change Biology, Volume 32, Issue 8, August 2026.
Microplastics disrupt ecosystem signaling through olfactory traps, altering predator–prey signaling and disrupting microbial communication and quorum sensing. ABSTRACT Microplastics (MPs) and their associated chemical additives are pervasive contaminants whose ecological impacts extend beyond organismal toxicity to fundamentally alter ecosystem ...
