Oxygen profiles measured in Pensacola Beach dry sand sediments between 2010 and 2014

This dataset contains oxygen profile measurements from Pensacola Beach, 2010-2014. Three oxygen profiles were measured with microsensors in order to assess the change in oxygen concentration in the oil contaminated beach during hot, warm, and cold periods of the year. Immediately after the excavation of one trench segment in the oil contaminated beach, O2 optode sensors (Presens fiberoptodes encased in hypodermic syringe needles with fiber tip protectors) were pushed approximately 10 cm horizontally into the sand at 5 cm depth intervals for the determination of O2 in the pore space. Profiles were measured from the surface to 50 cm depth. Despite the protection, sensors could typically not measure more than one profile and then had to be replaced.

本数据集包含2010-2014年彭萨科拉海滩的氧气剖面测量数据。为评估受石油污染海滩在一年中炎热、温暖和寒冷时期的氧气浓度变化，研究人员使用微传感器测量了三组氧气剖面。在受石油污染海滩的一段沟渠挖掘完成后，研究人员立即将氧气光极传感器（O₂ optode sensors，Presens光纤光极，封装于带光纤尖端保护装置的皮下注射针头内）以5厘米的深度间隔水平推入沙中约10厘米，以测定孔隙空间中的氧气含量。剖面测量范围为从表面至50厘米深度。尽管有保护措施，传感器通常只能完成一次剖面测量，之后便需更换。本数据集为以下出版物提供支持：Huettel, M., Overholt, W.
