Shiller, A M

In this thesis two separate marine chemical studies are described. The first study is concerned with the inorganic composition of fine particulate matter in the Santa Barbara Basin. In the second study, the difficulties in using simple models to examine the calcium carbonate-carbon dioxide system in the ocean are discussed. Several particulate profiles have been obtained in the Santa Barbara Basin off southern California. The inorganic composition of the particulates, as determined by thin-film x-ray fluorescence, reveals information regarding their origin and fate. Resuspension of fine sediments is found to be responsible for the major input of particulates to the basin water column. The second half of this thesis begins with an examination of calcium-alkalinity correlations in the North Pacific. It is found that reported deviations of calcium-alkalinity correlations from expected trends appear to be related to boundary processes (i.e., ocean circulation) rather than to previously ignored chemical reactions. This study also demonstrates the difficulties to be found in making corrections for changes in the preformed values of CO/sub 2/ system parameters.
