Methane storage in tropical meromictic lakes (Lakes Yambo, Pandin and Calibato, Luzon Is., Philippines)

These are data used in our manuscript entitled, "Controlling factors of methane dynamics in tropical meromictic lakes of different depths" which is submitted to the Journal of Geophysical Research: Biogeosciences. We observed temporal trends in methane (CH4) stored in the water columns of three Philippine lakes of different depths (shallow, moderately deep, and deep). We collected water samples, at various depths of lakes Yambo (0, 5, 15, 20, 25, 30, and 35 m), Pandin (0, 5, 15, 30, 40, 50, and 60 m), and Calibato (0, 5, 15, 40, 60, 80, 100, and 125 m) using a Niskin water sampler (General Oceanics, Miami, FL, USA), from April 2018 to February 2019, and measured dissolved CH4 concentrations using the procedure of Itoh et al. (2015). We also monitored the vertical profiles of various physicochemical parameters, including water temperature (○C), dissolved oxygen (DO; mg L–1), and conductivity (μs cm–1) using a multi-parameter sonde (Exo1, YSI Inc., USA).

本数据集所涉内容收录于我方提交至《地球物理研究：生物地球科学》杂志的论文《不同深度热带层状湖泊甲烷动态的控制因素》。论文中，我们对三个不同深度（浅、中深、深）的菲律宾湖泊水体中储存的甲烷（CH4）的时间趋势进行了观测。我们于2018年4月至2019年2月期间，利用Niskin水样采集器（General Oceanics，迈阿密，美国）在Yambo湖（0、5、15、20、25、30和35米）、Pandin湖（0、5、15、30、40、50和60米）以及Calibato湖（0、5、15、40、60、80、100和125米）的各层水体中采集水样，并采用Itoh等人（2015年）的方法测量了溶解CH4浓度。此外，我们还使用多参数声速仪（Exo1，YSI Inc.，美国）监测了包括水温（℃）、溶解氧（DO；毫克/升）和电导率（微西门子/厘米）在内的多种物理化学参数的垂直分布。气象参数包括
