Permafrost thaw threatens up to 3 million people in the Arctic

Permafrost thaw poses multiple risks to local Arctic communities, their livelihoods, infrastructure and environment. A transdisciplinary study led by Umeå University and others has identified key risks across four Arctic regions. This allows communities to adapt and make informed decisions.

Comprehensive, first-ever soil virus dataset represents untapped viral diversity, biogeochemical potential

Soils are among the largest viral reservoirs on Earth. Yet historically, soil viruses have been ignored. Recent work indicates the soil virosphere as a critical factor in human and environmental health, yet our understanding of global soil viral distributions, activities, and interactions with the soil microbiome remains limited.

This chapter in 2023's Ecohydrological Interfaces describes the seamless continuum of hydrological and #biogeochemical conditions in #riparian zones which blur the line between #groundwater, the hyporheic zone, and surface stream water.

This integration is crucial for the ecological integrity of water bodies, affecting everything from water temperature to #biodiversity.

`We find that upper-#ocean dissolved iron #dynamics were decoupled from those of ligands, which necessitates a process by which dissolved iron escapes ligand stabilization to generate a reservoir of authigenic #iron particles that settle to depth. When this ‘colloidal shunt’ mechanism was implemented in a global-scale #biogeochemical model, it reproduced both seasonal iron-cycle dynamics observations and independent global datasets when previous models failed`

Authigenic mineral phases as a driver of the upper-ocean iron cycle - Nature

Analysis of a new dissolved iron, ligand and particulate iron seasonal dataset shows that authigenic iron phases help control ocean dissolved iron distributions and the coupling between dissolved and particulate iron pools.
