Abstract

The urgent need to minimize the effects of climate change caused by increased greenhouse gases has generated interest in Ocean Alkalinity Enhancement (OAE) as a strategy for decreasing ocean acidity. A key aspect of implementing OAE involves monitoring chemical reactions in oceanic conditions, which are complex and involve a multitude of ions and compounds. This thesis aims to utilize the Infrared (IR) Spectroscopic signatures of solid products from potential OAE reactions. It records and explains the spectral changes that could occur when an alkaline earth hydroxide is added to water, forming carbonate minerals. This work serves as an essential catalog to help future researchers in OAE keep track of spectral features to look for.
