Supplementary table (Table S2) - Literature review dataset for "Modest role of methanotrophy in a high-methane emitting Yedoma thermokarst lake"

This dataset compiles methane (CH₄) cycling parameters from peer-reviewed studies of global lake ecosystems, with emphasis on high-latitude thermokarst and yedoma lakes. Key parameters include methane concentrations (CCH₄), actual/potential methanotrophic rates, dissolved organic carbon (DOC), oxygen (O₂), carbon dioxide (CO₂), O₂/CH₄ ratios, and associated metadata (ecosystem type, climate, season, lake depth, etc.). Data spans diverse lake types (thermokarst, glacial, boreal) and latitudes, supporting comparative analyses of methane production, oxidation, and emission drivers. Compiled to contextualize methane dynamics in thawing permafrost lakes (e.g., yedoma systems) under climate change.

本数据集整合了全球湖泊生态系统同行评议研究中的甲烷（methane, CH₄）循环相关参数，研究重点关注高纬度热喀斯特湖与雅德马冻土湖。核心参数涵盖甲烷浓度（CCH₄）、实际与潜在甲烷氧化速率（methanotrophic rates）、溶解性有机碳（dissolved organic carbon, DOC）、氧气（oxygen, O₂）、二氧化碳（carbon dioxide, CO₂）、O₂与CH₄的浓度比值，以及相关元数据（metadata，包括生态系统类型、气候、采样季节、湖泊水深等）。数据集覆盖热喀斯特、冰川、寒带等多样湖泊类型与纬度区间，可支撑甲烷产生、氧化与排放驱动因子的比较分析。本数据集的汇编旨在为气候变化背景下解冻永久冻土（permafrost）湖（如雅德马冻土系统）中的甲烷动态研究提供情境化支撑。
