Preface

This numeric data package was originally published in September of 1986, and included a printed document, and a magnetic tape. The printed document provided the revised TTO data on a microfiche; the format, description, and units for the origional TTO data; a sample listing of the origional TTO data; reprints of pertinent literature to describe both data sets; and a listing of the magnetic tape contents. The magnetic tape contained four data files: a descriptive file; a fortran data retrieval code to read and print the revised TTO data; the revised TTO data; and the origional TTO data.

Although this online version of NDP004/R1 varies slightly from the origional publication format, it provides comparable information. The data files have not changed, and are provided in their origional format. The major difference is that this electronic version does not include the following literature originally published within the printed documentation:

• Brewer, P.G., A.L. Bradshaw, and R.T. Williams. 1986. Measurements of total carbon dioxide and alkalinity in the North Atlantic Ocean in 1981. pgs. 348-370. In The Changing Carbon Cycle: A Global Analysis, J.R. Trabalka and D.E. Reichle editors, Springer-Verlag, New York.
• Takahashi, T., and P.G. Brewer. 1986. Hydrographic and chemistry data for the TTO/NAS expedition, April - October, 1981: Revised Carbon Chemistry data. (letter to CDIC).
