The Evidence for Linearly Scaling Ocean Gas Exchange With Sea Ice Needs Strengthening
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.Abstract Polar oceans are critical components of the oceanic uptake of atmospheric carbon dioxide. Estimates of this uptake across the air‐sea interface require parameterizations of gas transfer velocity that account for variable sea ice concentrations.

Earth's Future, Volume 14, Issue 7, July 2026.Abstract Near‐surface permafrost degradation has the potential to damage infrastructure needed to sustain Arctic communities, but risk assessments remain highly uncertain due to a limited representation of the Arctic circumpolar building stock. With deep learning building footprint detection and building occupancy classification models, we expand the ...

Latitudinal Gradients in Position and Climatology of Upper Tree Limits Across Europe
Journal of Biogeography, Volume 53, Issue 7, July 2026.ABSTRACT Aim The upper tree limit (UTL) marks the upper boundary of the realized niche of trees. It is commonly located below the treeline, which represents the cold boundary of the fundamental niche of trees. We hypothesized that the elevational offset between the UTL and the treeline is partly systematic and can be predicted using topographic and ...

Comparison of Different Algorithms to Orthorectify WorldView-2 Satellite Imagery
Algorithms, 2016 Due to their level of spatial detail (pixel dimensions equal to or less than 1 m), very high-resolution satellite images (VHRSIs) need particular georeferencing and geometric corrections which require careful orthorectification.
