Sediments of the northwestern Gulf of Mexico were analyzed for grain size and radiometric data (210-Pb, 234-Th, and 7-Be) to assess Hurricane Harvey impacts.
Sediments of the northwestern Gulf of Mexico were analyzed for grain size and radiometric data (210Pb, 234Th, and 7Be) to assess Hurricane Harvey impacts. Samples were collected from the Louisiana-Texas shelf in September and October 2017 using the ship R/V Acadiana. Sediment cores were obtained using a multi corer and subsampled at 2 cm depth intervals.
Sediment core subsamples were dried, homogenized, and subsequently analyzed. Grain size distribution was determined using laser diffraction after deflocculation in a 0.05% sodium metaphosphate solution, and disaggregation with an ultrasonic probe (Denommee et al., 2016). Radiometric data (210Pb, 234Th, and 7Be) were obtained using gamma spectroscopy (Maiti et al., 2010).
