============================== = Deep Sea Drilling Project = = Penetrometer Data Set = ============================== I. INTRODUCTION The Penetrometer test was performed onboard Glomar Challenger in the earlier Legs of the DSDP. The test is generally considered to be only a qualitative indicator of sediment strength. The test was subsequently discontinued and to our knowledge no in depth studies of these results was ever undertaken. Digitized data is available only for Legs 4, 6-15. Data was probably taken on other Legs, but not digitized. Depths reported in this file were computed at the time of the cruise and will reflect any corrections to corrections to core depths.

We were advised by the DSDP data management staff that the data are completly unstandardized. Penetrometer data were included only for the sake of completeness. Data were heavily edited to make the Leg, Hole, Core fields match the "Standard DSDP identifier" format used in all of the other data files, ie. leading zeros were removed and numbers aligned within the proper columns. No other editing was done.
