About World dataset: J. L. Reid, and A. W. Mantyla
This data set is provided freely in the anonymous
ftp directory at Scripps Institute of Oceanography by Drs. Reid and Mantyla, and was formatted for Web by NOAA/PMEL/EPIC.
Additional variables, such as neutral density, have been
computed and included in the EPIC files.
Note: Arctic data is included in the Pacific category.
Here is the README file from the Scripps anonymous ftp directory
(at HOST minerva.ucsd.edu).

These data files have been compressed using UNIX
utility compress. They can be returned to readable
ascii files using compress -d, or uncompress.
The set of about 12,000 stations that J. L. Reid and
A. W. Mantyla have used in various world ocean studies
is available for anyone who wishes to use it.
These data have been accumulated for the purpose of
global ocean studies and are not intended for fine scale
analyses. Each station represents, to our knowledge,
the best station available for that locality at the time
of the selection.
The set was compiled over many years and from many
sources and has been brought up to date as new data have
become available. Most of the data were obtained from
NODC. The others came directly from various P.I.s in
various formats and may lack some NODC parameters such
as ship, country, and institution codes and NODC assigned
number.
It should be noted that these are edited data files and
an accurate account of deletions and corrections is,
unfortunately, not available. In some cases these data
may not agree exactly with versions published later or
data supplied later by the NODC or an originator.
We chose only stations that reach close to the bottom.
This means, unfortunately, that the set is rather sparse
near the equator. We believe that the temperature and
salinity measurements are acceptable. However, some of
the oxygen and nutrient data are quite poor. We have not
eliminated them from the data set, but simply ignore them
in our hand-contouring. We would have eliminated them if
we had realized the troubles they will cause in computer-
contouring or instant atlases, but this set was begun
before such methods were generally available.
A few known systematic errors such as IGY oxygens or
early Discovery oxygens and silicates have been adjusted,
based upon deep comparisons with more modern data. In a
few localities, stations have been reoccupied many times
and a mean composite profile is given; at other localities,
only the most recent, or the best sampled profile is saved
and all others deleted. Because of the large-scale scope
intended for this data array, some closely-spaced stations
have been omitted. When needed, those stations can be
retrieved from tapes of the entire cruise.
We add to this set as appropriate new data become
available. We suggest that those who have received
earlier versions might wish to get the current set. We have
not yet added the WOCE data from the North and South Pacific
Ocean or many of the recent expeditions in the Pacific. We
are in the process of updating the Pacific Ocean data set
as data become available. The data are mostly sorted
geographically, but the newer materials are in a separate file
in cruise order.
