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.
