Permafrost degradation and soil erosion as drivers of greenhouse gas emissions from tundra ponds

Environmental Research Letters
Climate change poses a serious threat to permafrost integrity, with expected warmer winters and increased precipitation, both raising permafrost temperatures and active layer thickness.

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Improving Micro– and Macro–Algae Speciation Mapping for Management: A Field‐Validated Sentinel‐2 and Sentinel‐3 Intercomparison in the Indian River Lagoon

GeoHealth, Volume 10, Issue 10, October 2026.
Abstract In recent years, the health of the Indian River Lagoon (IRL) on Florida's east coast has fluctuated due to recurring harmful algal blooms (HABs). These events typically involve cyanobacteria, dinoflagellates, or A. lagunensis (brown tide) causing water‐quality degradation and seagrass decline.

Characterizing Permafrost Distribution Along the Hudson Bay Railway Using Temperature‐Calibrated Electrical Resistivity Tomography

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract As the climate warms, understanding permafrost distribution along linear infrastructure is a key aspect of assessing, mitigating, and adapting to the risks associated with permafrost thaw. Electrical resistivity tomography (ERT) is becoming an increasingly common tool for evaluating permafrost distribution at the infrastructure scale.

Can the Carbon Storage Function of a Degraded Mountain Wet Meadow Be Restored?

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Sierra Nevada meadows experienced intense livestock grazing in the 19th century, resulting in a shift from deep‐rooted highly productive perennial clonal sedges to short‐lived and shallow‐rooted plants. The current meadow vegetation contains >20% bare ground and <10% cover of highly productive clonal sedges and rushes. We hypothesized that the

Spatiotemporal Variability of Water Transit Time Distribution Across an Alpine Stream Network

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Water transit time (TT), the time elapsed from its entrance into a catchment and its exit through a stream section, is a useful indicator of catchment transport dynamics. Its distribution (TTD) is typically estimated at a single cross section where tracer data are available.

A Simple Temperature‐Controlled Method for Preserving Viability in Human Pluripotent Stem Cell‐Derived Retinal Organoids During Shipment

FASEB BioAdvances, Volume 8, Issue 10, October 2026.
A lithium‐free temperature‐controlled shipping system (YOTI) stabilizes physiologic temperatures during overnight transport of mature human iPSC‐derived retinal organoids. Compared to conventional ambient shipping, YOTI reduces temperature fluctuations, preserves retinal lamination, decreases cell death, and maintains rod photoreceptor marker ...
