Molecular level characterization of oil and aggregate oxidation products: Mesocosm LTMOSE, a Long Term Marine Oil Snow Experiment, Fourier transform ion cyclotron mass spectrometry (FTICR-MS) data

Marine oil snow samples were collected during the mesocosm/roller table experiments and analyzed by Fourier transform ion cyclotron resonance mass spectrometry coupled with electrospray ionization (ESI-FTICR-MS). The dataset contains the raw mass-to-charge ratio (m/z) and their peak intensity data directly from the instrument and the processed excel files used for analysis. In this project, seawater obtained from Galveston Bay, containing plankton but filtered to exclude zooplankton and debris, was mixed with either water accommodated fraction (WAF) or chemically enhanced WAF (CEWAF) in mesocosm tanks. A control experiment containing neither WAF nor CEWAF was also conducted. After fixed periods of incubation tanks were destructively sampled for marine snow. Marine snow was analyzed with Fourier transform ion cyclotron resonance mass spectrometry coupled with electrospray ionization.

本数据集的海洋油雪样品采集自中宇宙/滚台受控实验，并通过电喷雾电离耦合傅里叶变换离子回旋共振质谱法（ESI-FTICR-MS）完成分析。数据集包含仪器直接产出的原始质荷比（m/z）数据及其峰强度信息，以及用于分析的已处理Excel文件。本项目中，研究人员从加尔维斯顿湾采集海水，该海水含有浮游生物，但经过滤去除了浮游动物与碎屑；随后将其分别与水可溶组分（WAF）或化学增强型水可溶组分（CEWAF）混合于中宇宙培养槽内。同时设置了不含WAF与CEWAF的对照组实验。经过固定时长的孵育后，对培养槽进行破坏性采样以获取海洋油雪样品。后续采用电喷雾电离耦合傅里叶变换离子回旋共振质谱法对海洋油雪样品开展分析。
