OCEAN DRILLING PROGRAM July 1990 DATA FILE DOCUMENTATION * Revised edition PHYSICAL PROPERTIES MEASUREMENTS SHEAR STRENGTH I. INTRODUCTION The Shear Strength data file contains information generated onboard the JOIDES Resolution by the shipboard physical properties scientists and technicians. The strength tests may be done with several different devices. The dataset contains data from four different instruments: the Motorized Torque Transducer device, the Wykeham-Farrance device, the Hand Held Torvane, and the SoilTest Pocket Penetrometer. The tests can be run on a whole core sample in the horizontal orientation of the core (into the end of the core), on a split core sample in the vertical orientation of the core (into the split core surface), or on a remolded sediment sample. Each Strength data record contains raw data and calculated values for strength tests. Each record represents strength evaluations for a single core sample, but may contain two different test runs for every sample which may be in the same or in different orientations (although the second run would generally be made on a remolded sample). When two tests are run, the sensitivity is calculated as the ratio of the original shear strength of the sample to its remolded shear strength and recorded in the data record. Spring calibration and vane calibration data files are also available upon request. However, the pertinent calibration data are included in the Shear Strength data file. Additional information in the calibration data files that may be of interest includes comments concerning the springs and vanes used, the dates that the instruments were calibrated, and the heights and diameters of the vanes. The Spring calibration file is included at the end of this document.

EXPLANATION OF THE DATA ITEMS LEG - Number identifying the cruise. The Ocean Drilling Program started numbering the cruises of the JOIDES Resolution at Leg 101. SUBLEG - Letter identifying a subleg or transit. A subleg is the continuation of a Leg after a port call; it often involves a crew change. SITE - Number identifying the site. A site is the position of a beacon around which holes are drilled. HOLE - Letter identifying the hole. DATE_TIME - The date and time when the test was performed. OBSERVER - Three or four letter code identifying the person performing the strength analysis. CORE - Number identifying the core. Cores are numbered serially from the top of the hole downward. CORETYPE - A letter code identifying the drill bit/coring method used to retrieve the core. The coretype codes are: B - Drill Bit C - Center Bit D - Positive Displacement H - Hydraulic (Advanced) Piston Core I - Interstitial Water (only used on Legs 101 to 116) M - Miscellaneous N - Downhole Mud Motor (Navidrill) P - Pressure Core Barrel R - Rotary S - Side Wall Core W - Wash Core X - Extended Core Barrel SECTION - A core is cut into 1.5-meter-long sections that are numbered serially from the top of the core. A core with full recovery will have 7 sections and a core catcher and be approximately 9.8 meters long. TOP_INTERVAL - The location of the top of a sample within a section in centimeters. BOTTOM_INTERVAL - The location of the bottom of a sample within a section in centimeters. SAMPLE_CODE - An alpha code identifying the investigator or test for which the sample was taken. PIECE - Number identifying a rock piece. A piece is one rock fragment or a group of rock fragments that can be fitted together. SUBPIECE - Letter identifying an individual rock fragment within a piece. TEST_TYPE - Method designating type of device used to perform the strength test. The codes for the instruments are: TD - The Motorized Torque Transducer Device SP - The Wykeham Farrance Device TV - The Hand Held Torvane PM - The SoilTest Pocket Penetrometer DIRECTION - Direction in which the test was performed. The codes are: W - Designates Whole Core with device inserted in the horizontal orientation of the core (into the core end). S - Designates Split Core with the device inserted in the vertical orientation of the core (into the split core surface). CAPACITY - Capacity setting (adapted vanes) of the Hand Held Torvane. Values are "L" for low, "M" for medium, and "H" for high, where L = LOW_CAPACITY_CONSTANT = 200 * MAX_CAPACITY M = MEDIUM_CAPACITY_CONSTANT = 1000 * MAX_CAPACITY H = HIGH_CAPACITY_CONSTANT = 2500 * MAX_CAPACITY. MAX_CAPACITY - Maximum capacity of Torvane instrument in g/cm**2. SPRING - ID of the spring used in the strength test. SPRING_CONSTANT - Constant of spring used for strength tests. VANE - ID of the vane used in the strength test. VANE_CONSTANT - Constant of vane used in strength test. TORQUE - The maximum torque reading in gram-centimeters or spring rotation in degrees of torque. ROTATION or STRAIN - The rotation of the vane, at maximum torque, in degrees. STRENGTH - Calculated value of the strength of the sediments. For the spring calculations, STRENGTH = VANE_CONSTANT * SPRING_CONSTANT * TORQUE * TRANSDUCER_CONSTANT. (kPa) (1/cm**3) (g-cm/deg) (deg) (kPa-cm**2/g) For transducer calculations, STRENGTH = VANE_CONSTANT * TORQUE * TRANSDUCER_CONSTANT. (kPa) (1/cm**3) (g-cm) (kPa-cm**2/g) For Torvane calculations, STRENGTH = LOW_CAPACITY_CONSTANT * TORQUE * TRANSDUCER_CONSTANT or STRENGTH = MEDIUM_CAPACITY_CONSTANT * TORQUE *TRANSDUCER_CONSTANT or STRENGTH = HIGH_CAPACITY_CONSTANT * TORQUE * TRANSDUCER_CONSTANT, (kPa) (g-cm) (fraction (kPa-cm**2/g) of max capacity) where TRANSDUCER_CONSTANT = 0.0980665 = conversion factor for converting g/cm**2 to kilo-Pascal(kPa). For the pocket penetrometer and other methods, the following apply: STRENGTH = STRENGTH * 0.001 (kg/cm**2) (g/cm**2) (kg/g) STRENGTH = STRENGTH * 0.0980665 (kPa) (g/cm**2) (kPa-cm**2/g) STRENGTH = STRENGTH * 0.48824 (lb/ft**2) (g/cm**2) (lb/g)(cm**2/ft**2). SENSITIVITY - The ratio of the sample's original shear strength to its remolded shear strength. COMMENTS - Any comments concerning the strength test or sample. ADD_DATE - The date and time that the record was first entered into the dataset. CHANGE_DATE - The date and time when the record was last changed.
