The mud area off the northern Shandong Peninsula is a critical region for sediment and organic carbon (OC) burial in the Yellow Sea. Based on a sediment borehole with 210 Pb-derived sedimentation rate of 0.63 cm/a, multiple proxy parameters including grain size, total organic carbon (TOC), total nitrogen (TN), stable carbon isotope (δ 13 C), and nitrogen isotope (δ 15 N) were analyzed to reconstruct centennial-scale OC sources...

Temperate forests are key terrestrial carbon sinks, yet their capacity to sequester carbon is often limited by nitrogen (N), a nutrient whose availability is declining in many ecosystems. Among factors contributing to declining N availability, climate‐driven changes in soil hydrology could force N loss via the emission of both nitric oxide (NO) and nitrous oxide (N 2 O); however, forecasting these losses is challenging because...
