To elucidate the sources and spatial variations in organic matter in surface sediments from Lingdingyang of the Pearl River Estuary, 18 surface sediment samples were collected and analyzed for obtaining total organic carbon (TOC), total nitrogen (TN), atomic TOC/TN ratio (C/Natom), stable carbon and nitrogen isotopes (δ13C, δ15N), and glycerol dialkyl glycerol tetraethers (GDGTs). A three-endmember framework was constructed us...

Mangrove ecosystems effectively sequester heavy metals, making their sediment distribution and ecological risk assessment vital for coastal protection. This study focuses on the mangrove forests on both sides of the Donghai Island embankment in Huguang Town, Zhanjiang Bay, analyzing the content, spatial distribution, and potential ecological risks of heavy metals (Cu, Zn, Cd, Pb, Cr, As, Hg) in surface and vertical sediment pr...

Statistical downscaling methods require the stationarity assumption, that is, the statistical relationship between the grid‐scale input and the observed precipitation does not change between present‐day and climate change conditions. We implemented a skill score to test the stationarity assumption in two simple and popular statistical downscaling methods, quantile‐mapping and the generalized linear model method Rglimclim, in d...
