Hurricane Harvey impacts on biogeochemistry of sediments assessed using samples collected in Mission-Aransas Estuary in south Texas from June 2017 to March 2019

The impact of Hurricane Harvey on sediment biogeochemistry was assessed using sediment samples collected from June 2017 to March 2019 in Mission-Aransas Estuary in south Texas. Sediment core samples were sectioned and analyzed for mineral grain size, organic carbon and nitrogen, stable isotopic composition, pigments, plus sediment alkane and polycyclic aromatic hydrocarbons.

本研究以2017年6月至2019年3月采自得克萨斯州南部米申-阿兰萨斯河口（Mission-Aransas Estuary）的沉积物样品为实验材料，评估了哈维飓风（Hurricane Harvey）对沉积物生物地球化学的影响。研究人员对沉积物岩心样品进行分层切片处理，并对其矿物粒度、有机碳与氮含量、稳定同位素组成、沉积色素，以及沉积物烷烃和多环芳烃（polycyclic aromatic hydrocarbons）进行了分析测定。
