CHRONOS ADP core-depth data file format

The core-depth data file specifies the depth range, in meters below sea floor (mbsf), for each core obtained from a sample hole. It should be a tab-delimited plain text file with two lines of header information, as in the following example:

 278 2.00    19910225	1	Extracted from CD-ROM
 1	 0 	 6
 2	 101 	 110.5
 3	 110.5 	 119.5
 4	 120 	 127.5
 5	 129.5 	 138.5
 6	 139 	 148.5
 7	 148.5 	 157.8
 8	 158 	 167.5
 9	 167.5 	 176     

This file follows the format of the DSDP and ODP core-depth files used in the original (Macintosh) ADP. The five tab-delimited fields in the first line represent the hole ID, a program version number, a date, a file type number, and a comment. The Java version of ADP extracts the hole ID from the first field and displays the entire line following the Core file info label at the top of the application. However, after extracting the hole ID, the code does not try to parse the line any further, so the remainder of the line could really contain anything. If you are preparing an input file, use this line to convey the hole ID and any other helpful information regarding the data provenance.

The second line contains headers for the three columns of data. Java ADP simply skips over this line, so its contents have no effect on program operation.

The third and following lines should contain core number, top depth (mbsf), and bottom depth (mbsf) for each core. The cores do not have to be listed sequentially and gaps (no core 6, for example) are allowed.
