Chemogeography of Dissolved Organic Matter in Lake Sediments Structured by Climatic and Geochemical Factors
Dissolved organic matter (DOM) plays a key role in lake carbon cycling, yet the geographic patterns and environmental associations of sediment DOM chemodiversity remain poorly understood. Here, we analyzed sediment DOM from 92 lakes across China spanning a broad latitudinal gradient of 23–50°N using Fourier‐transform i...
