Short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruises WB-2010-08, WB-1109 and WB-1110 in the northern Gulf of Mexico from 2010-08-11 to 2010-12-09

This dataset contains short-lived radioisotope (SLRad) data collected aboard R/V Weatherbird II cruises WB-2010-08, WB-1109 and WB-1110 in the northern Gulf of Mexico from 2010-08-11 to 2010-12-09. 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 the 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. Cruise documentation was provided for each of the R/V Weatherbird II cruises. The cruises were led by chief scientists Dr. Benjamin Flower (WB-1109) and Dr. David Hollander (WB-2010-08 and WB-1110).
