ODP Technical Note 10


TABLE OF DOWNHOLE TOOL USAGE DURING ODP LEGS 101-146 The following table lists tools run during the first 46 legs of the Ocean Drilling Program, through November 1992. The table is not detailed, but is instead intended to point the interested investigator toward appropriate volumes of ODP Initial Reports and Scientific Results. The table indicates only that a specific tool was run down the pipe at each specified site, not whether the deployment was successful, nor if data are available. Interested scientists should contact the Data Librarians at ODP/TAMU and LDEO, or individual tool developers, to determine if data exist for a particular run.

For third-party and specialty tools, the developer affiliation (for U.S. scientists) or country of origin (for non-U.S. scientists) is also listed. The following list of tool abbreviations is used for wireline-logging instruments in Table B-1.
