Dataset: Grain size and radiometric data from multi-core sediments collected Fall 2017 from the R/V Acadiana in the northwestern Gulf of Mexico 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).
