Geological oceanography topics that will be covered include: Structure and evolution of ocean basins, types and properties of marine sediments, sediment transport processes and characterizing coastal regions. Physical oceanography topics that will be covered include: basic physical laws, properties of the water and the ocean, air-sea interactions, general circulation and coastal processes.
Oceanography ("ocean"= the marine environment, and "graphy"= the study of) is literally the study of the marine environment. In practice, oceanography is an interdisciplinary science at the intersection of geology, chemistry, physics and biology. Marine Science II focuses on fundamental concepts in chemical and biological oceanography. The study of chemical oceanography will encompass dissolved components, stratification, chemical tracers, marine pollution, ocean acidification and global warming. This will lead to an introduction to biological oceanography, which will include organismal biology, marine adaptation and fisheries. In-class lectures will provide the students with the foundation to understand the principles discussed and will be supplemented with discussion of the modern ways in which these disciplines are pursued.

The coastal ocean has a physical regime that is distinct from that of the open ocean. This physical regime contributes to disproportionally high levels of ecological productivity associated with these areas. Because of the often close coupling of physical and biogeochemical processes in the costal ocean, the solutions to the problem facing these ecosystems typically require interdisciplinary perspectives. The objective of the course is to introduce the main physical processes and fisheries in the coastal ocean. The course will provide an overview of the physics operating in the coastal ocean and link the physical forcings to biogeochemical processes and ecosystem function. The course will cover topics from shelf break-open ocean interactions to the fundamental processes operation in estuarine environments. The end goal is for graduate students to acquire a fundamental understanding of the physical mechanisms driving the circulation and the associated hydrographic properties in the coastal ocean and how those physical phenomena link to biogeochemical processes.
Coastal Ecosystem Dynamics will allow students to investigate the basic principles of ecosystem structure and function. The course is divided into 2 parts: an instructional phase for learning basics of ecosystem modeling, and a student-led investigation of the structure and function of a variety of coastal ecosystems. This approach will give the student a set of quantitative tools for modeling ecosystems. Also, students will learn to evaluate differences and similarities of energy and nutrient processing in disparate ecosystems. There will be one 2 hr class meeting each week during which students will learn to use the ecological modeling software packages 'Ecopath' and 'Ecoism'. During the initial period, students will 'dissect' published models (obtained from the Internet) as a mechanism to understand the utility of ecosystem modeling as well as the basics of this particular software. The second half of the course will be devoted to student-constructed ecosystem models. The models will be constructed from data and pathway descriptions in Alongi's 'Coastal Ecosystem Processes' (CRC Press). A synthesis of these models will be constructed and placed on the WWW.
