Frequently Asked Questions
Q. The hole I am interested in is not included in the log database. Is it missing?
A. If the hole you are interested in is not listed, then no logging data were collected at that hole. Core data from that hole may be available through IODP-TAMU at http://iodp.tamu.edu/tasapps/ and at http://iodp.tamu.edu/database/ .
Q. I cannot access the hole that I am interested in. It looks like I need a password.
A. All holes are subject to a 1-year moratorium after the post-cruise meeting. During this time only members of the shipboard party are allowed access to the data. After one year, the data becomes available to the general public. The list of the moratorium dates is at http://iodp.tamu.edu/database/moratorium.html .
Q. How can I get access to password-protected data?
A. To access password-protected data you need to obtain written permission from the co-chiefs and staff scientist of the expedition during which the log data was acquired. You can find the list of the expedition scientific participants at http://iodp.tamu.edu/scienceops/expeditions.html . If your request is approved, submit written proof via email to the IODP-USIO Log Data Services Manager. Then, you will be granted a username and password that will give you access to the IODP log and core databases.
Q. In the case of password-protected data, do I need a different username and password to access the IODP core database?
A. No, you can use the same username and password.
Q. Where can I get information about the processing performed at each hole?
A. The Documents section of each Index Page contains detailed information about the processing performed for each dataset at a particular hole.
Q. I am not familiar with log and logging tool acronyms. Where can I find their definition?
A. The list of all the acronyms used in DSDP/ODP/IODP is available in the Documents section of the Index Page (see previous question). The list of the definitions of all the data files of each hole is available as a File Dictionary link at the top of the Index Page of a particular dataset.
Q. I am searching for the data types of a specific hole and I have come up with page-long lists of individual files. How do I get a list of the data types available at a specific hole?
A. To get a list of data types instead of individual files, you must click on the active link for the hole in the ‘Results:Hole’ or ‘Results:Files’ page. This will take you to the Index Page of the hole.
Q. I noticed that not all data types are listed in the Results:Files page.
A. A complete list of the data types of a specific hole is available on the Index Page of the hole. To access the Index Page, click on the hole number in the Results:Files page (see previous questions)
Q. Is any industry-standard format available in this database?
A. The DLIS (Digital Log Interchange Standard) is available for both original (raw) and processed data. Data in this format are available only through the Index Page of a specific hole.
Q. Where can I get information about the logging tools currently used in the logging program?
A. You can find a description of the tools and their applications under Tool & laboratories ->Logging tools->Tool description on the main search page of this database or by clicking on http://iodp.ldeo.columbia.edu/TOOLS_LABS/tools.html
Q. Where can I get information about the logging tools that are no longer used in the logging program?
A. You can find a description of 'legacy' tools and their applications under the Tool & laboratories ->Logging tools->Tool description on the main search page of this database or by clicking on http://iodp.ldeo.columbia.edu/TOOLS_LABS/tools.html . Then click on the Legacy Tool button at the bottom of the page.
