Source: Personnel with the Rolling Deck to Repository (R2R) program at the
Lamont-Doherty Earth Observatory (LDEO) made available to NCEI these data
and information files in one or more compressed tar files, which, also,
contained BagIt tag files. In addition, they provided NCEI with MD5
checksums for these data and information files.

Actions: After transferring the compressed tar file(s) and MD5 checksum file
for CH0109_602520_r2rctd and CH0109_603093_r2rnav from LDEO, NCEI extracted
these data and information files from the compressed tar file(s) and then
verified their integrity by recalculating their MD5 checksums and comparing
them against those from LDEO. If NCEI was able to verify the integrity of
the data and information files, they removed the compressed tar file(s).

Files:
about/
Under this directory are files generated by NCEI with ancillary information
about the data submission.

0178906_lonlat.txt -
  Geographic coordinates showing where these data were collected
  (longitude in the left column and latitude in the right column, both
  in degrees).
 
0178906_map.jpg -
  Map showing sampling locations of these data.

data/0-data/
This directory contains the data files as submitted to NCEI.

Some sub-packages in 0-data contain supplemental BagIt files.
1. data/ - subdirectory contains the payload of actual data files
2. bag-info.txt - summary metadata for the dataset including submitter
     (R2R), date, bag size(#bytes), cruise ID#, fileset ID#, instrument
     type, etc
3. bagit.txt - lists version# of BagIt specification
4. file-info.txt - lists R2R file ID#, checksum, path, and size (#bytes)
     of each file in the data/ subdirectory
5. manifest-md5.txt - lists path and checksum of each file in the data/
     subdirectory
6. tagmanifest-md5.txt - lists path and checksum of each .txt file in
     the bag
