Data associated with the publication: Similarities in storage and transport of sulfate in forested and suburban watersheds, despite anthropogenically elevated suburban sulfate

This study focuses on differences in sources and dynamics of sulfate in a forested versus suburban streams in an unglaciated region underlain by schist. Sulfate in streams is both an important nutrient and potential pollutant that is linked with the nitrogen, carbon, and phosphorus cycles. There are uncertainties about how suburban sulfate sources including septic, fertilizer, road salt, and infrastructure impact sulfate fluxes. We studied suburban and forested headwater catchments nested within a 381-ha catchment to estimate the magnitude of sulfate sources and evaluate the effects of land use on transport to streams. Data for this study include discharge, sulfate concentrations, water hydrogen and oxygen values, and sulfate sulfur and oxygen isotope data, as well as results of models described in the paper.

本研究聚焦于一片以片岩（schist）为基底的无冰川作用区域内，森林溪流与城郊溪流中硫酸盐的来源及动态差异。溪流中的硫酸盐既是重要的营养物质，也是潜在污染物，其与氮、碳、磷循环密切相关。目前对于化粪池、化肥、道路融雪盐及基础设施等城郊硫酸盐来源如何影响硫酸盐通量，仍存在诸多认知不确定性。本研究选取嵌套于381公顷流域内的城郊与森林源头集水区作为研究对象，旨在估算硫酸盐来源的总量，并评估土地利用对硫酸盐向溪流输送过程的影响。本研究所用数据集包含流量、硫酸盐浓度、水体氢氧同位素值、硫酸盐硫氧同位素数据，以及论文中提及的模型运算结果。
