In situ fluorometers were deployed during the Deepwater Horizon (DWH) Gulf of Mexico oil spill to track the subsea oil plume. Uncertainties regarding instrument specifications and capabilities necessitated performance testing of sensors exposed to simulated, dispersed oil plumes. Dynamic ranges of the Chelsea Technologies Group AQUAtracka, Turner Designs Cyclops, Satlantic SUNA and WET Labs, Inc. ECO, exposed to fresh and artificially weathered crude oil, were determined. Sensors were standardized against known oil volumes and total petroleum hydrocarbons and benzene-toluene-ethylbenzene-xylene measurements-both collected during spills, providing oil estimates during wave tank dilution experiments. All sensors estimated oil concentrations down to 300 ppb oil, refuting previous reports. Sensor performance results assist interpretation of DWH oil spill data and formulating future protocols.
在墨西哥湾深水地平线（DWH）石油泄漏期间，部署了原位荧光计来追踪海底石油羽流。由于仪器规格和功能存在不确定性，因此需要对暴露于模拟分散油羽流的传感器进行性能测试。对暴露于新鲜和人工风化原油的 Chelsea Technologies Group AQUAtracka、Turner Designs Cyclops、Satlantic SUNA 和 WET Labs，Inc. ECO 的动态范围进行了测定。利用在溢油期间采集的已知油体积和总石油烃以及苯-甲苯-乙苯-二甲苯测量值对传感器进行了标准化，这为波槽稀释实验期间的石油估算提供了依据。所有传感器都能估算低至 300 ppb 的石油浓度，这驳斥了之前的报告。传感器性能结果有助于解释 DWH 溢油数据并制定未来的方案。
