Nitrogen transformations in riverine sediments, Hampshire Avon, United Kingdom

The dataset contains denitrification, anaerobic ammonium oxidation (anammox) and nitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via direct, field-based measurements in seasonal campaigns conducted between spring 2013 and winter 2014. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.

本数据集涵盖英国汉普郡埃文流域（Hampshire Avon catchment）河流沉积物的反硝化作用、厌氧氨氧化（anaerobic ammonium oxidation, anammox）与硝化作用活性数据。研究针对6条分别位于地质背景迥异的子流域（地质类型依次为黏土、砂岩与白垩岩）内的河流展开。所有数据通过2013年春季至2014年冬季期间开展的多季野外实地直接测量获取。此外，数据集还包含原位速率测量前于孔隙水中测定的各项化学参数。
