Soil and lake water temperatures of Iceland (2019-2021)

Temperature loggers (Thermochron DS1922L or DS1925L ibuttons, Maxim Integrated Products) were used to record soil and lake water temperatures at 1- to 6-hour intervals and 0.0625°C resolution. Soil temperature loggers were double wrapped in plastic bags (Whirlpak), placed inside plastic containers (PolyCon), sealed with electrical tape, and buried at 10 cm depth. Water temperature loggers were similarly double wrapped, placed inside 50 mL plastic containers (Nalgene or Falcon), sealed with electrical tape, and suspended at known depths in the lake.

本研究采用温度记录仪（Thermochron DS1922L或DS1925L型iButton，美信集成产品公司（Maxim Integrated Products）制造），以1至6小时的采样间隔、0.0625℃的温度分辨率，记录土壤与湖水温度。土壤温度记录仪需双层封装于Whirlpak塑料袋中，随后置入PolyCon塑料容器，以电工胶带密封后埋设于10厘米深度处；湖水温度记录仪则采用相同封装流程：双层包裹后置于50毫升Nalgene或Falcon塑料容器中，以电工胶带密封，并悬挂于湖泊的已知深度位置。
