Figure F27. Raw APCT tool data for estimating in situ temperatures. Only the portion of data immediately before, during and immediately after penetration of the probe into the subsurface is shown. For an example of the entire temperature history of a deployment, see "Downhole Tools and Pressure Coring" in the "Explanatory Notes" chapter. The ODP core identification number associated with each run of the APCT tool is indicated in the upper left corner of the graph. B. DVTPP temperature data. The ODP identification for the cores preceding and following tool deployment is indicated.
