Short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruises WB-0815 and WB-0915 in the northern Gulf of Mexico from 2015-08-16 to 2015-10-01

This dataset contains short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruises WB-0815 and WB-0915 in the northern Gulf of Mexico from 2015-08-16 to 2015-10-01. 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. The cruise documentation was provided for the R/V Weatherbird II cruises WB-0815 and WB-0915. The cruises were led by chief scientists Dr. Steve Murawski and Dr. David Hollander.
