This course will introduce students to the natural chemical systems of the hydrosphere. These systems become the backdrop by which aquatic ecosystems thrive. The hydrosphere also plays a significant role in the transport of matter and energy around the world which drives climate and food production. Students will study ocean-atmospheric interactions, circulation patterns, and major chemical processes in both fresh and saltwater systems. This course is approved as an elective in the Marine Science Curriculum. Pre-requisites: CHEM 106.
