Short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruise WB-0717 in the Gulf of Mexico from 2017-07-22 to 2017-07-28

This dataset contains short-lived radioisotope (SLRad) data collected aboard R R/V Weatherbird II cruise WB-0717 in the Gulf of Mexico from 2017-07-22 to 2017-07-28. SLRad data were 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. Cruise documentation was provided for cruise WB-0717. The cruise was led by chief scientists Dr. Steve Murawski and Dr. David Hollander.
