Supervising Scientist: Adam Klaus
JOIDES Resolution Downhole Measurements Lab
OverviewThe ODP runs the most advanced suite of routinely used downhole instruments of any scientific project in the world today. These tools change frequently and rapidly in terms of design and capabilities, and downhole tools specialists sailing on the JOIDES Resolution are often confronted with a bewildering array of instruments and proceedures. With the short time available between establishment of the ship schedule and the start of individual legs, shipboard scientists often do not have access to instruments or even manuals, prior to sailing. The purpose of this page is to provide contact with the people involved in the planning of downhole tool deployment and to give brief descriptions of key aspects of those tools. For many of the ODP downhole tools, fully detailed operating instructions written by the tool designers or manufacturers are available at ODP and on board the JOIDES Resolution, and will only be briefly summarized here. Factors that are important in planning and conducting measurements are discussed in ODP Technical Note No. 10..
"ODP" will be used to refer to the ODP Science Operator at Texas A&M University (TAMU), and "LDEO", will refer to the ODP Logging Contractor, Lamont-Doherty Earth Observatory.
ODP and LDEO divide responsibilities for downhole tools in a general way as follows: LDEO is responsible for providing logs measured with tools run on the seven-conductor logging cable (or "wireline"), whereas ODP is responsible for those tools used with the drill string and/or the nonconducting coring line (or "sandline").
