Prerequisites: Graduate standing in a meteorology or related discipline, or permission by instructor.

Course description:

This course provides an introduction and overview to the weather and climate in the Earth’s polar regions. We will first discuss the climatology, dynamics, and thermodynamics of the Arctic and Antarctic atmospheres. We will then focus on special topics of significance in polar regions, including the atmospheric boundary layer, sea ice, polar vortices, polar lows, and oceanic circulations. There will be no exams in this course, and instead, this course aims to develop and strengthen your skills in teaching, research, and service. The format of this class will consist of two meetings per week, with one meeting time devoted to instructor-lead lectures, and one meeting time devoted to student-lead discussions of relevant peer-reviewed journal articles.

Required text:

None. Readings will be distributed either in class or through Canvas.

Grading:

Grading weights will be determined as shown below. In general, a letter grade of ‘B’ is earned if a student at least minimally demonstrates competence in the course material. An ‘A’ means the student has demonstrated exceptional knowledge of the material, and students will receive a letter grade of ‘C’ or below if they have not demonstrated that they meet course expectations. Rubrics are provided with further details of how student’s are evaluated in the grade components listed below.

Format:

Class meetings with alternate each week between instructor-driven lectures and student-driven scientific journal discussions.

Term project:

There will be a semester-long term project in which you will perform a scientific research project. Dead- lines/due dates are listed in the Grading section above. The outcome of this project is a scientific paper consisting of the following sections in the final draft: (1) Title, (2) Abstract, (3) Introduction, (4) Data and Methods, (5) Results, (6) Conclusions or Summary, and (7) References. These sections are described in further detail in Chapter 4 of “Eloquent Science”. The final paper will be evaluated on your adherence to the scientific method based on a rubric provided (Rubric_science_WrittenPaper_list.pdf).

You will also turn in a first draft of your paper. This first draft must contain a “Title,”, “Abstract,”

“Introduction”, “Data and Methods”, and “References” section, and at least one preliminary figure (with the accompanied description in your draft) that is a possible candidate for the “Results” section of your final draft. See Chapters 11 and 12 of “Eloquent Science” for details on Figures, tables, and references.

Evaluations of your first and final drafts will be by 2 anonymous peers, and the instructor. A factor in the grade of your final draft, in addition to those listed on the rubric, is the quality for which you addressed the peer reviews of your first draft. Guidance on peer reviews, and how to respond to peer reviews, are provided in Chapters 19-21 of “Eloquent Science.”

Approximately one week before your final draft is due, you will have a 20 minute block of time to present your research on this term project orally to the class. You must allocate at least 5 minutes of this time for questions. Students are expected to read Chapters 25-26 of “Eloquent Science” for information on who to prepare and give oral presentations. The final research presentation will be evaluated on your adherence to the scientific method based on a rubric provided (Rubric_science_OralPresentation_list.pdf)

For further reading about writing scientific papers, preparing peer reviews, addressing peer reviews, and preparing oral presentations, students are expected to read Chapters 4, 11, 12, 25, and 26 of “Eloquent Science,” which is provided on the course Canvas page. Grading rubrics are provided, which are based on these readings:

Exams:

There will be no written in-class exams. There will be a term project that involves both written and oral components, described below.

Final exam:

There is no written, in-class final exam. The time slot of the final exam is scheduled for Monday May 11 10:30 am-12:30 pm, which is reserved for the term project, if necessary.

Policy for use of calculators, mobile devices, tablets, or laptops:

As a courtesy to other students and to the instructor, please refrain from cell phone use during class and please set your ringer to silent mode. Tablet computers or laptops are allowed during lectures, but only for the purpose of taking notes.

Collaboration:

Collaboration with other students is encouraged, so long as you follow the OU Academic Integrity Policy. Feel free to utilize the discussion board on the course Canvas page. It is not required that you participate, and there will be no grade for participating in these online discussions. This aim is to provide an easily accessible forum to assist you as you learn subtleties within topics via discussions with your colleagues.

University Policies Academic Integrity:

Cheating is strictly prohibited at the University of Oklahoma, because it devalues the degree you are working hard to get. As a member of the OU community it is your responsibility to protect your educational investment by knowing and following the rules. For specific definitions on what constitutes cheating, review the Student’s Guide to Academic Integrity at

http://integrity.ou.edu/students.html.

To be successful in this class, all work must be yours and yours alone. In group work, you MUST actively engage with group members and contribute to your group’s preparation and presentation. Your individual student assignments MUST be prepared by you. You may seek outside help in preparing your assignments, but you must present it and provide credits where appropriate. Should you see someone else engaging in academic misconduct, I encourage you to report it to myself or directly to the Office of Academic Integrity Programs. That student is devaluing not only their degree, but yours, too. Be aware that it is my profes- sional obligation to report academic misconduct, which I will not hesitate to do. Sanctions for academic misconduct can include expulsion from the University and a failing/unsatisfactory grade (U) in this course, so don’t cheat. It’s simply not worth it.

Religious Observance:

It is the policy of the University to excuse the absences of students that result from religious observances and to reschedule examinations and additional required classwork that may fall on religious holidays, without penalty.

Reasonable Accommodation Policy:

Students requiring academic accommodation should contact the Disability Resource Center for assistance at (405) 325-3852 or TDD: (405) 325-4173. For more information please see the Disability Resource Center website http://www.ou.edu/drc/home.html. Any student in this course who has a disability that may prevent him or her from fully demonstrating his or her abilities should contact me personally as soon as pos- sible so we can discuss accommodations necessary to ensure full participation and facilitate your educational opportunities.

Title IX Resources and Reporting Requirements:

For any concerns regarding gender-based discrimination, sexual harassment, sexual misconduct, stalking, or intimate partner violence, the University offers a variety of resources, including advocates on call 24.7, counseling services, mutual no contact orders, scheduling adjustments and disciplinary sanctions against the perpetrator. Please contact the Sexual Misconduct Office 405-325-2215 (8 to 5, M-F) or OU Advocates 405-615-0013 (24.7) to learn more or to report an incident.

Adjustments for Pregnancy/Childbirth Related Issues:

Should you need modifications or adjustments to your course requirements because of documented pregnancy- related or childbirth-related issues, please contact your professor or the Disability Resource Center at 405/325-3852 as soon as possible. Also, see http://www.ou.edu/eoo/faqs/pregnancy-faqs.html for an- swers to commonly asked questions.
