Porewater data across a catena in the Luquillo Experimental Forest, Puerto Rico.

Landscape topography can influence biogeochemical processes in wet tropical forest soils. This dataset contains porewater concentrations of organic acid (acetate) from 2018 (February 22 to November 14) across a catena in the Luquillo Experimental Forest (LEF), Puerto Rico. The attached CSV file contains information on sampling date, location (El Verde field station) in LEF, topographic positions (ridge, slope, and valley, respectively), depth (unit: cm), and acetate concentration (unit: µM). Porewater concentrations of acetate were lower in the valley as compared to the ridge and slope topographic positions. This dataset can facilitate our understanding of the biogeochemical cycling of carbon and nutrient associated with complex topography in wet tropical forest soils.

景观地形可调控湿润热带森林土壤的生物地球化学过程。本数据集收录了2018年2月22日至11月14日期间，波多黎各卢奎略实验森林（Luquillo Experimental Forest, LEF）内一处地形序列上的孔隙水有机酸（乙酸盐，acetate）浓度数据。附带的CSV文件包含以下信息：采样日期、卢奎略实验森林内的采样点位（埃尔韦尔野外台站）、地形位置（依次为山脊、坡地与山谷）、土层深度（单位：厘米）以及乙酸盐浓度（单位：µM）。相较于山脊与坡地地形位置，山谷区域的乙酸盐孔隙水浓度更低。本数据集有助于增进我们对湿润热带森林土壤中与复杂地形相关的碳与养分生物地球化学循环的认知。
