Blue Nitrogen Follows the Fate of Tidal Wetlands

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Tidal wetlands sequester carbon (C) at much higher rates per area than other ecosystems, helping to offset C emissions. The burial of organic C in tidal wetland soils, “blue C”, is tightly linked to the cycling of nitrogen (N), which is a key pollutant and limiting nutrient for many ecosystems.

An HHT–ANN Framework for Short‐Term Kp Forecasting

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract The geomagnetic activity index Kp is an important indicator of solar wind–magnetosphere coupling, and accurate 3‐hr‐ahead forecasting is important for space‐weather monitoring and warning. Because upstream solar wind and interplanetary magnetic field (IMF) signals are strongly nonlinear and nonstationary, methods based only on conventional ...
