Short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruise WB-0517 in the Gulf of Mexico from 2017-05-11 to 2017-05-23

This dataset contains short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruise WB-0517 in the Gulf of Mexico from 2017-05-11 to 2017-05-23. SLRad data are generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to the base of cores. SLRad data generated include sample activity as disintegrations per minute per gram(dpm/g) of 1) Excess Thorium-234 (234Thxs) activity, which is calculated by measuring the total Thorium-234 (234ThTot) activity and the subtraction of the measured or estimated “Supported” Thorium-234 (234ThSup) activity, 2) Excess Lead-210 (210Pbxs) activity, which is calculated by measuring the total Lead-210 (210PbTot) activity and subtraction of the measured background "supported" Lead-210 (210PbSup) activity {average of Lead-214 (214Pb) at 295 kiloelectron volts (keV), 214Pb at 351keV, and Bismuth-214 (214Bi) at 609keV}, 3) Cesium-137 (137Cs) activity, and 4) Berilium-7 (7Be) activity. The dataset contains the location, date, water depth of core site in meters (m), core collection date, site identification (ID), core identification (ID), top depth of Interval in millimeters (mm), bottom depth of interval in millimeters (mm), average depth of interval in millimeters (mm), average of top and bottom depths and a variety of SLRad data. The cruise documentation was provided for the R/V Weatherbird II cruise WB-0517, led by chief scientists Dr. Steve Murawski and Dr. David Hollander.
