Abstract Reservoirs exert a profound influence on the cycling of dissolved organic matter (DOM) in inland waters by altering flow regimes. Biological incubations can help to disentangle role that microbial processing plays DOM within reservoirs. However, complex composition poses great challenge analysis such data. Here we tested if interpretable machine learning (ML) methodologies contribute capturing relationships between molecular reactivity and composition. We developed time‐specific ML models based 7‐day 30‐day simulate biogeochemical processes Three Gorges Reservoir over shorter longer water retention periods, respectively. Results showed extended time likely allows successive degradation molecules, with stochasticity exerting non‐negligible effect at initial stage incubation. This study highlights potential enhancing our interpretation dynamics time.

Thousands of mass peaks emerge during molecular characterization natural dissolved organic matter (DOM) using ultrahigh-resolution spectrometry. While assigned to certain formulas have been extensively studied, the uncharacterized that represent a significant fraction and convey biogenic elements energy previously ignored. In this study, we introduce term dark DOM (DDOM) for unassigned explored its characteristics environmental behaviors data set 38 extracts covering Yangtze River-to-ocean continuum. We identified total 9141 DDOM molecules, which exhibited higher weight greater diversity than subset with formulas. Although contributed smaller relative abundance, it significantly impacted composition bulk DOM. A portion was found increase abundance across river-to-ocean These compounds could contain halogenated molecules might high potential contribute refractory carbon pool. With underline contribution pool emphasize more research is needed understand global biogeochemical cycles sequestration.

The property of groundwater dissolved organic matter (DOM) subjected to anthropogenic recharge (AGR) might be affected by the water quality disparity between surface and natural groundwater. However, diverse molecular scenarios DOM under uneven recharging levels remain largely unexplored. We combined characteristics, carbon isotopic signatures molecules, end-member mixing analysis explore sensitivity potential tracking capabilities AGR along with gradients. Our findings suggested that enriched diverse, saturated, labile, sulfur-rich amplifying abundance intensity, which intensified Additionally, S-containing molecules their indicators like CHOS% (with threshold values 7.82%) exhibited high predictive power for recognition. major (diversity, saturated degree, stability) indicated 13C-containing were similar whole pool. Notably, specific (C12H10O5S C15H16O12), although not detected in all samples, exhibit robust stability or favorable solubility, rendering them candidates as AGR-sensitive molecules. R13C/12C ratio C19H24O5 emerged most tracer, exhibiting a strong correlation smallest deviation from theoretical line, signifying its optimal suitability precise source apportionment. This study offers novel insights into impacts contributes fostering harmonious balance human activities resource sustainability.
