Chemical Composition of WAF made through a novel passive dosing method tested during the GOMCOAST mesocosm using Gulf Of Mexico COASTal water

Mesocosm experiments were performed with Gulf of Mexico seawater collected from the Texas coastline, near TABS buoy R (29° 38.1000'N, 93° 38.5020'W) and was amended with nutrients. The two treatments in triplicate were analyzed for oil composition were 1) Control with blank silicone (Si) tubing device, 2) passively dosed Water accommodated oil fraction (Si-WAF). The oil composition data presented here are PAH (polycyclic aromatic hydrocarbons), Total petroleum hydrocarbons (TPAHs), and individuals aliphatic hydrocarbons (nC10-nC35).

本研究以墨西哥湾得克萨斯海岸线附近TABS浮标R点位（北纬29°38.1000′，西经93°38.5020′）采集的海水为实验介质，开展中型生态系统（mesocosm）实验，并向实验体系中添加了营养盐。本实验设置两组处理，每组均设置三次生物学重复，随后对两组样品的油品组成进行分析：1）空白对照组：采用空白硅酮（Si）管装置；2）被动投加水包油组分（Si-WAF）。本次公开的油品组成数据涵盖多环芳烃（PAH，polycyclic aromatic hydrocarbons）、总石油烃（TPAHs）以及碳数范围为nC10-nC35的正构烷烃。
