Characterization of Seawaters by Ion Chromatography – Comparison of ionic patterns and balances
Abstract
Accurate characterization of seawater composition is required to understand chemical changes occurring in the ocean and their impact on marine ecosystems. In this work, three different seawater samples collected from the Portuguese Coast were analyzed by Ion Chromatography. For matrix comparison purposes, the same procedure was performed in two samples collected in two different locations in the Baltic Sea, known to be composed essentially by brackish water with a salinity gradient typical of estuaries. Special focus on calcium and magnesium ions is presented since both ions are essential for biological processes in the ocean s environment. The uncertainty associated with the results of ionic composition were evaluated to further use in the ionic balance and to assess the constancy of the proportion of major ionic components in the analysed seawaters. The collected information is of key usefulness for characterizing major components and for determining long-term trends or spatial variations of seawater composition.
