Variations in modelled and measured hyperspectral remote sensing reflectance
… these features were not determined by individual seawater constituents, but they proved useful as a tool for water type classification. The sign of the integral between 400-455nm discriminated between open ocean and coastal waters, and coastal sub-types could be distinguished by applying cluster …

Evolution of the Geohydrologic Cycle During the Past 700 Million Years
… contribute to short-term (<1 Ma) variations in seawater composition and isotopic signatures.

Investigating the Fate of Mg-bearing Calcium Carbonates During Early Diagenesis
… history also reflects the secular variation of seawater through time and is a key mineral in probing past change in climate.This study investigates whether dolomite can form from seawater in the presence of carboxylated organic matter (COM), and if the presence of COM further facilitates Mg …

Abyssal benthonic foraminifera and the carbonate saturation of sea water and a benthonic foraminferal carbonate saturation history for the Cape Verde Basin for the last 550,000 years
… correlated with the degree of saturation of seawater with respect to calcium carbonate. The relative abundance of cibicidids, miliolids, Uvigerina and Globocassidulina subglobosa increases in saturate water and the relative abundance of Nuttlaides umbonifera increases in undersaturated water. …

Boron in Foraminiferal Calcite as an Indicator of Seawater Carbonate Chemistry
… whose physical and chemical nature reflect the seawater conditions in which they grow. Thus, fossil tests preserved on the sea floor represent an archive that may be used to investigate the composition of ancient seawater. With the aim of improving our understanding of past ocean-climate links, …

Dissolved inorganic and particulate iodine in the oceans
Analytical methods have been developed for the determination of iodate, iodide and particulate iodine in sea water. Iodate is converted to tri-iodide and the absorbance of tri-iodide at 353 nm is measured. The precision of this method is ca. ±3%. Iodide is first separated from most other anions by …
