Sediment porewater nutrient, sulfide, pH, and alkalinity, sediment redox, and bulk sediment carbon, nitrogen, chlorophyll a and phaeopigments.

Measurements of sediment porewater nutrient, sulfide, pH, and alkalinity, sediment redox, and bulk sediment carbon, nitrogen, chlorophyll a and phaeopigments measurements over years at a variety of sites and salinities throughout the Plum Island Sound estuary.本数据集为普拉姆岛湾河口（Plum Island Sound estuary）内多个采样站位、不同盐度条件下的长期观测数据，测定指标涵盖沉积物孔隙水营养盐、硫化物、pH、碱度，沉积物氧化还原电位，以及全量沉积物的总碳、总氮、叶绿素a（chlorophyll a）与脱镁色素（phaeopigments）含量。
