Limnological parameters related to seasonal differences and potential biological drivers of the methane paradox in Lake Attersee and Mondsee, Austria

This dataset contains the raw data related to the investigation of seasonal differences and potential biological drivers of the methane paradox in Lake Attersee and Mondsee, Austria. Lakes were sampled in July 2024, November 2024, April 2025, and June 2025. The dataset consists of five excel files containing high-resolution water column profiles of environmental parameters, laboratory measurements of nutrients and cell abundances, underwater light intensity data, 16S rRNA gene amplicon sequencing, and stable isotope labelling experimental results. The 16S rRNA gene amplicon sequencing raw data is available at the Sequence Read Archive under the Bioproject Accession PRJNA1422683.本数据集包含与奥地利阿特湖（Lake Attersee）和蒙德湖（Lake Mondsee）甲烷悖论的季节差异及潜在生物驱动因子调查相关的原始数据。研究团队于2024年7月、2024年11月、2025年4月及2025年6月对两座湖泊开展采样。 数据集包含五个Excel文件，涵盖环境参数高分辨率水柱剖面数据、营养盐与细胞丰度的实验室测定数据、水下光强数据、16S rRNA基因（16S rRNA gene）扩增子测序数据，以及稳定同位素标记实验结果。 其中，16S rRNA基因扩增子测序原始数据已提交至序列读取档案（Sequence Read Archive），生物项目登录号为PRJNA1422683。
