METEO 451: Introduction to Physical Oceanography

Spring 2019 Semester 

DESCRIPTION: The primary objective of this course is to describe the circulation of the ocean and present a theoretical basis for understanding it. The focus is on the large-scale, basin-wide features of the ocean circulation, such as: (1) the subtropical ocean gyres, which contain the wind-driven western boundary currents like the Gulf Stream; (2) the equatorial oceans, which respond rapidly to external forcing to produce phenomena like El Niño; and (3) the thermohaline circulation, which acts as a slow regulator of the earth's climate. A main goal is to demonstrate to meteorology students that the ocean is not a static, passive lower boundary to the atmosphere but a dynamic, evolving entity that is intimately coupled to the atmosphere through the exchange of heat, momentum, and water. Thus, the oceans affect weather and climate. 

TIME & PLACE: 9:05−10:20 AM Tuesday (105 Walker) and Thursday (105 or 126 Walker). 

INSTRUCTOR: Raymond Najjar (pronounced NAY-jar), Professor, Department of Meteorology
Office: 522 Walker Building
Phone: 814-863-1586
Email: rgn1@psu.edu
Office hours: Monday 3:30−4:30 pm, Tuesday 10:30−11:30 am, Wednesday 2:30−3:30 pm. 

REQUIRED COURSES: Prerequisite: Meteo 421 (Atmospheric Dynamics). Policy: Students who do not meet these prerequisites may be disenrolled according to Administrative Policy C-5 if they do not have the proper prerequisite override. Students who add the course after being disenrolled according to this policy are in violation of Item 15 on the Student Code of Conduct: https://studentaffairs.psu.edu/support-safety-conduct/student-conduct/code-conduct.

CLASS STRUCTURE: Readings will be assigned weekly and discussed in class on Tuesday. Please read the assigned material before coming to class on Tuesday. Thursdays will start with a 10−15 minute quiz on the previous week’s reading, followed by a laboratory exercise using Matlab (see below). 

LABORATORY EXERCISES: On Thursdays in 126 Walker, you will work on one of six laboratory exercises, each of which you will be given 2−3 weeks to complete. Upload completed labs to Canvas on the Friday before the next lab starts. The exercises will typically require several additional hours of work outside of the lab periods. The assignments will engage you directly in oceanographic data analysis and modeling using the programming language Matlab. Matlab is also very useful in science and engineering and thus many of your prospective employers will be pleased that you know it. I anticipate that most of your learning will occur as you do these assignments. 

REQUIRED TEXTBOOK: Najjar, R. G., Meteo 451 Notes: Introduction to Physical Oceanography. This is available free on Canvas. Readings will be assigned primarily from this source. There may be a few additional required readings from other sources, which I will make available to you if you do not already have them. Readings are assigned for each topic as shown in the detailed syllabus. 

QUIZZES: There will be weekly, closed-book, equally weighted quizzes given during the first 10−15 minutes of each Thursday class period. The quizzes will be taken in 105 Walker. When you are done you may go to 126 Walker to work on the lab. The quizzes will cover the weekly reading and associated lecture of the previous week in order to give you time to synthesize the material. If you are unable to take a quiz because of extenuating circumstances, please let me know ahead of time and we will schedule a makeup. 

FINAL EXAM: To assess your overall comprehension of the material presented during the course, a final exam will be given during finals week (date and time to be determined).

GRADES: A: 92−100%; A−: 88−91%; B+: 84−87%; B: 80−83%; B−: 75−79%; C+: 71−74%; C: 63−70%; D: 50−62%; F: <50%. Weighting: 20% quizzes, 60% labs, 20% final exam.

ACADEMIC INTEGRITY POLICY: I expect all submitted work to be your own. Feel free to discuss assignments with others, but never ever (I really mean it) copy another’s work. If it appears that there is copying on an assignment, I will begin the formal Disciplinary Action Procedure as outlined by our college. Students who present other people's work as their own will receive at least a 0 on the assignment and may well receive an F or XF in the course.  Please see: Earth and Mineral Sciences Academic Integrity Policy: http://www.ems.psu.edu/undergraduate/academic-advising/forms-and-procedures/academic-integrity, which this course adopts. To learn more, see Penn State’s "Plagiarism Tutorial for Students."
