This course focuses on the elemental cycles of the major bioactive elements carbon, nitrogen, phosphorus, oxygen, and iron in the ocean. Topics include the biological and microbial carbon pumps, nitrogen fixation, iron fertilization, the carbon-climate system, ocean acidification and deoxygenation. This course will provide insight and corresponding critical review of the current outstanding scientific questions being pursued by ocean biogeochemists.
Introduces students to the four oceanographic disciplines: the geology of the ocean basins, including the creation of oceans and continents. The physics of the seas, including the origin of the ocean currents and their effect on the Earth's climate. The chemistry of the ocean waters, including how the distribution of elements reflects circulation and biology. The life in the ocean, including animals, plants and microbes, and humanity's influence on them. Special fee. Lab.
The chemical processes that determine the composition of aquatic systems such as rivers, lakes, groundwater and the ocean. The goal is to quantitatively understand the behavior of inorganic species such as carbon dioxide, nutrients, trace metals and inorganic pollutants in natural waters. Topics include, acid-based equilibria, carbonate chemistry, reduction-oxidation reactions, organic complexation and mineral precipitation and dissolution. Lab. Prereq: 1 year of college calculus and chemistry or geochemistry.
This course investigates the physical and biogeochemical processes that determine the composition of seawater. Topics include biological effects on chemistry, ocean nutrient cycles, air-sea gas exchange, radiogenic and stable isotopes as tracers of ocean processes, sediment and tace-metal chemistry. Prereq: MATH 426and CHEM...
