Unexpectedly high fluxes of phosphorus and iron at the sediment-water interface during the frozen period

This is a compilation of data on DGT-labile phosphorus and iron at the sediment-water interface for 11 sampling sites in the Xingkai Lake watershed during winter and spring, as well as HR-Peeper data.本数据集收录了兴凯湖流域11个采样点位在冬季与春季的沉积物-水界面处扩散梯度薄膜（DGT）活性磷与铁的相关数据，同时包含高分辨率孔隙水采样器（HR-Peeper）的实测数据。
