Figure F64. A. Temperature data for Site U1352. An exponential decrease in temperature is expected for the time interval shown and used to estimate ambient temperature. This decrease is evident in Cores 317-U1352B-10H, 15H, 20H, and 38X. Data for the time interval ti to tf (solid circles) were used to estimate asymptotic temperature. See Table T27 for these values. B. Resulting geothermal gradient (46.0°C/km). Solid circles = reliable temperature measurements. APCT-3 = third-generation advanced piston corer temperature tool, SET = Sediment Temperature tool.
