data/0-data/recovered is originators data recovered by Keith Levinson from flat file
databases originally created by Phil Hadsell.

data/0-data/opdb is originators data recovered by Keith Levinson from the Ocean
Profile Database (OPDB).

The subdirectory <top>/data/0-data/recovered of this accession contains
 data that were reassembled from one or more NODC standard format
 databases, known as MULDARS (MULti-Discipline Archives Retrieval System)
 data. MULDARS was operational at NODC from approximately 1970-1995.
 During this period, most new data were received as or converted to one
 or more MULDARS standard data formats, with each format known as a "file
 type". Each "file type" was represented by an alphanumeric identifier -
 it's "file alias" - such as C100 (for low resolution bottle cast data),
 F291 (for Meteorology, Oceanography and Wave Spectra from Buoys), etc.
 The format of each NODC "file alias" is available upon request from the
 NODC or in NODC accession 0001164.

 The subdirectory <top>/data/0-data/opdb of this accession contains data
 that were recovered from a legacy NODC profile data database, the Ocean
 Profile Data Base (OPDB). The OPDB was operational from approximately
 1995-2002. Profile data, primarily data from bottle casts,
 bathythermographs, and STD/CTD casts were converted from their original
 formats into the NODC standard "P3" format. However, data in the /opdb
 directory is structured using standard pre-P3 data formats, i.e., Ocean
 Station Data (SD2) and Universal Bathythermograph (UBT) format. Details
 about the "P3", SD2 and UBT formats are available upon request from the
 NODC or in NODC accession 0001164.

 NOTE: Much of the data in the /opdb and/or /recovered directories was
 used in the production of the NODC World Ocean Database products,
 beginning in 1994. As such, profile data may be duplicated as a result
 of merging data from NODC originator accessions with data products like
 the NODC World Ocean Database.
