Instructor: Christina Ravelo
We focus on the development of Earth as a habitable planet, from its origins to human impacts on global geochemical cycles in the ocean and atmosphere. We seek to define the scientific basis for understanding the magnitudes and temporal scales of these effects.
You are expected to have a background equivalent to high school chemistry and to have passed Subject A if enrolling for W credit. General Education Codes: T2, W elective

Professor: Ken Bruland
This course is designed to provide an introduction to the marine environment stressing the interaction of physical, chemical, geological and biological factors in the ocean. The course provides the oceanographic background for studies in marine biology.
Prerequisites: Chemistry 1C, Physics 6B or 7B, and Mathematics 11B or 19B.
Students taking the prerequisite physics and math courses concurrently may enroll in the course with permission from the instructor.
The instructor is Professor Ken Bruland <http://natsci.ucsc.edu/acad/oceansci/kwbCV.html>.
For more details, check out the class web site and syllabus <http://wwwcatsic.ucsc.edu/~ocea101/> from last year.
Instructors: Mary Silver, Raphael Kudela
This course provides a discussion of selected topics in marine pelagic ecology, especially regarding physical and biological factors affecting production in marine food chains, adaptations to the pelagic habitat, and the distribution of planktonic organisms.
Prerequisite: Biology 20B is required, plus one additional marine science course is recommended as preparation.
Undergraduates should enroll in OCEA 140. (Also offered as Biology 146. Students may not receive credit for both courses.) Enrollment restricted to seniors, or juniors may enroll with permission of the instructor.
Graduate students should enroll in OCEA 240. (They may not receive credit for OCEA 240 if they've already taken OCEA 140 or BIOL 146.)
The instructors are Mary Silver <http://natsci.ucsc.edu/acad/oceansci/mwsCV.html> and Raphael Kudela <http://natsci.ucsc.edu/acad/oceansci/rmkCV.html>.
For more details, check out the class web site and syllabus <http://natsci.ucsc.edu/acad/oceansci/os140.html> from last year.

Overview of marine geology and of this course
What are the characteristics of the seafloor and the ocean basins?
Seafloor provincesOcean basins, continental drainage basins
Hypsometric curve, depth-age and area-age relationships for ocean crust/lithosphere
How are these characteristics explained in the context of plate tectonics?
Major plates and plate boundariesDistribution of seismic and volcanic activity, heat flow
Paleomagnetism and the age of the oceanic crust
Driving mechanisms, paleogeographic reconstructions
What are the distributions, sources, and characteristics of oceanic sediments?
The context: ocean circulation, oceanic biogeochemical cycles, and particle transportPlate stratigraphy: sediment distribution in space and time
Calcium carbonate sedimentation and the CCD: global, regional, and local
Opaline silica sedimentation
Other sediment types: detrital, authigenic, organic carbon
Particle distributions and sediment reworking
How do we define sediment ages? What are the effects of organisms on the sediment record?
Sediment dating and sediment accumulation ratesBioturbation
What are the roles of fluids in ocean sediments and ocean crust?
Interstitial water in marine sedimentsHydrothermal systems
What is the structure of the oceanic crust? What are the effects of the processes of formation, aging, and alteration?
Structure of oceanic crust, types of evidenceFormation and aging of oceanic crust, heat budgets
What are the characteristics of the continental margins? What processes are important in their formation and evolution?
Classification and distribution of continental marginsPassive margins, active margins
What do oceanic sediment records tell us about ocean and climate history?
Goals and methods of paleoceanography, climate history of the last 3 m.y.
Climate and ice volume history of the past 100 m.y.
Paleogeographies and past ocean circulation
Proposal presentations (students)
Overview and the future
Problem sets (3)
Leading scheduled class discussions of journal articles (at least once for undergraduates, at least once for graduate students)
Participation in formal and informal class discussions
Preparation of one set of weekly study questions (graduate students)
Mid-term exam (in class)
Take-home final exam
Proposal and oral presentation of proposal
Evaluations will be based on performance on these requirements, on overall participation in class and discussion section, and on comprehension of course material demonstrated in interactions with instructor. The expectations, some of the assignments, and the context for evaluation are different for undergraduate and graduate students in this class. Class lectures and information from discussion sections are critical to your understanding and performance in this class.
