Data Supporting: Water mass circulation and microbial processing drive the basin-scale distribution pattern of dissolved organic matter in the South China Sea

The supplementary dataset includes molecular composition data of solid-phase extracted (SPE) dissolved organic matter (DOM) collected at 3 stations in the South China Sea during a research cruise in April and May 2020.本补充数据集包含2020年4至5月科考航次期间，于南海3个站位采集的经固相萃取（solid-phase extracted, SPE）处理的溶解态有机质（dissolved organic matter, DOM）的分子组成数据。
