Abstract:

Short-lived Radioisotope (SLRad) data were generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to base of cores. SLRad data generated include sample activity as disintegrations per minute per gram (dpm/g) of: 1) Excess 234Th (234Thxs) activity, which is calculated by measuring the total 234Th (234ThTot) activity and the subtraction of the measured or estimated “Supported” 234Th (234ThSup) activity, 2) Excess 210Pb (210Pbxs) activity, which is calculated by measuring the total 210Pb (210PbTot) activity and subtraction of the measured background 210Pb (210PbSup) activity (average of 214Pb at 295keV, 214Pb at 351keV, and 214Bi at 609keV), 3) 137Cs activity, and 4) 7Be activity. Where appropriate, age dating was calculated in calendar years for 234Th and 210Pb activity profiles and mass accumulation rates (MAR) expressed as g/cm2/yr using the Constant Rate of Supply model. This dataset supports the publication: Larson, R. A., Brooks, G. R., Schwing, P. T., Holmes, C. W., Carter, S. R., & Hollander, D. J. (2018). High-resolution investigation of event driven sedimentation: Northeastern Gulf of Mexico. Anthropocene, 24, 40–50. doi:10.1016/j.ancene.2018.11.002

Purpose:

Provide age control for sediment cores as well as mass accumulation rates (MAR) and inventories to assess depositional patterns and variability over past ~100 years and following the Deepwater Horizon (DWH) event.
