Figure F336. Multisensor track measurements for Expedition 312 show depth variations in magnetic susceptibility, bulk density from gamma ray attenuation (GRA), and natural gamma ray. No volume correction has been applied to GRA bulk density values. Only data from core pieces longer than ~8 cm are shown. Expedition 312 data are listed in Table T51. We suspect that recalibration of the GRA instrument at the beginning of Expedition 312 produced a decrease in estimated bulk density (Fig. F337), although we have no way to test this conjecture. Unusually high spikes are labeled with the core numbers in which they occur. High values of all three parameters occur in Core 312-1256D-184R (Unit 1256D-74).
