In memory of friendship and the pleasure of his company, in recognition of his many contributions to the GEOSECS program:

This book, which is primarily the result of his efforts, is gratefully and affectionately dedicated by his colleagues and shipmates.

The GEOSECS Program was conceived by a handful of far-sighted and the shoreside laboratory construction and improvements were geochemists and physical oceanographers in 1967.

The number of casts at "small volume" stations was also for the Indian Ocean, and the fraction of "small volume" stations was reduced from roughly one-half to roughly one-fifth of the total. These "small volume" stations consisted of a single "deep rosette" cast which provided a CTD profile and a profile of 22 thirty-liter samples.

PRECISION OF GEOSECS SHIPBOARD DATA

1 Preface Ideally, we would like to establish the precision with which it is possi­ ble to dip into a homogeneous solution and determine a constituent over The utility of any set of data depends, ultimately, on the precision with periods long enough that errors due to changes in standards, operators and which that data has been measured. An important part of the GEOSECS pro­ instrument drift are included. Clearly none of the above methods meet this gram is the acquisition of precisely determined profiles of salinity, tempera­ ideal. ture, dissolved oxygen, nutrients, total carbon dioxide and alkalinity.

These targets represented realistic limits that could be approached stationary water column was invalid. during routine operations using the best methods available. During the GEOSECS Pacific and Indian Oceans Expeditions the design of the track excluded station reoccupation. Further, the shortage of time, the depth of the water column and perhaps the inclinations of the chief scientists led to a decreased number of deliberate duplicate samplings. However, HYDROGRAPHIC, NUTRIENT, AND OXYGEN DATA sufficient replications and instances of adiabatic water columns were encountered so that some reasonable precision estimates may be attempted. During the GEOSECS expeditions three methods of obtaining precision estimates were attempted: Methods of Operation, Sampling and Analyses 1.

In general, two casts level of the constituent, the mean difference between the first and second were made at each station, each cast having two rosettes with a total of 22 bottle tripped at the same depth should be zero, and the standard deviation to 24 bottles. The lower rosette was equipped with a Neil Brown CTD for of the difference will be a measure of the overall precision attained by the in-situ measurement of conductivity, temperature, and pressure.

Furthermore, on the basis of about 200 measurements of pCO ~ Niskin samplers made of PVC and analyzed for the alkalinity and dissolved in water samples, it has been found that the alkalinity, total CO~ concentration total inorganic CO ~ using the potentiometric acid titration method.
