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至2019年，采样点位于美国弗吉尼亚州格洛斯特角的砂质地下河口（sandy subterranean estuary, STE）。实验采用季节性振动取芯法采集了0至100厘米（cm）深度的沉积物样品，将每段10厘米的岩心分样用于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；此外，还对每段岩心分样的氯化钾浸提液中的可提取营养盐浓度进行了分析检测。
