Short-lived radioisotope (SLRad) data collected R/V Weatherbird II cruise WB-0814 in the northern Gulf of Mexico from 2014-08-14 to 2014-08-28

This dataset contains short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruise WB-0814 in the northern Gulf of Mexico from 2014-08-14 to 2014-08-28. 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 the R/V Weatherbird II cruise WB-0814. The cruise was led by chief scientists Dr. Steve Murawski and Dr. David Hollander.
