Data for: Composition and lability of riverine dissolved organic matter: Insights from thermal slicing ramped pyrolysis GC-MS analysis

The data include chemical analysis of high molecular weight dissolved organic matter (HMW-DOM) collected from nine North American rivers, including stable carbon and nitrogen isotopes, total hydrolyzable amino acids, and pyrolysates through thermal slicing ramped pyrolysis GC-MS.

本数据集涵盖从北美九条河流采集的高分子量溶解态有机物（HMW-DOM）的化学分析数据，具体包含稳定碳、氮同位素组成、总水解氨基酸含量，以及采用热切片程序升温裂解气相色谱-质谱联用（GC-MS）技术获得的裂解产物分析结果。
