Biogeochemical data from sediment cores collected from a shallow, sandy subterranean estuary (STE) in Virginia USA from 2018 to 2019

These data were collected during 2018-2019 from a sandy subterranean estuary (STE) located in Gloucester Point, Virginia, USA. Seasonal vibracores collected sediment from 0-100 centimeters (cm). Ten-centimeter core sections were used in isotope tracer incubations with 15N-labeled substrates to measure potential denitrification and anaerobic ammonium oxidation (anammox) rates. Extractable nutrient concentrations in potassium chloride extracts were also analyzed for each core section.本数据集采集于2018—2019年，采集自美国弗吉尼亚州格洛斯特角的沙质地下河口（sandy subterranean estuary，STE）。研究人员通过季节性振动柱状采样，获取了0~100厘米深度的沉积物样品。将沉积物岩芯切割为每10厘米一段的分段样品，用于15N标记底物的同位素示踪培养实验，以测定潜在反硝化速率与厌氧氨氧化（anaerobic ammonium oxidation，anammox）速率。同时针对每段岩芯样品的氯化钾浸提液，开展可提取态营养盐浓度分析。
