GEOS/MSL 695 Field techniques in interdisciplinary sea-ice research (2 CR)

Brief course description and rationale

            This is a course for graduate-level students that is open to post-graduate professionals from relevant fields; openings may also exist for a small number of advanced undergraduate students with appropriate background with permission from the instructors. The course offers hands-on introduction to the principal field techniques employed in sea-ice studies of an interdisciplinary (geophysical-biogeochemical) nature. The course focuses on sea ice as an instructive example of the close intertwining between ocean, ice and biosphere processes and humans in the polar regions and the transdisciplinary importance of the ice cover in the Arctic system. The course will be held with the support of the Barrow Arctic Science Consortium (BASC) in Barrow, Alaska and consists mostly of field-based instruction and completion of different research modules with a laboratory component, some introductory lectures and evening seminars/discussions.

           The course is organized such as to encourage interdisciplinary approaches to the problems posed, addressing in particular the themes of temporal and spatial variability of geophysical and biogeochemical variables at different scales and the central role sea ice plays in the Arctic through the services it provides to ecosystems and human activities. The course is designed as an international effort at the peak of the International Polar Year (IPY) and includes a group of recognized experts as contributors for the different modules (see below).

Student Learning Outcomes:

The goal of this course is to introduce students to different approaches and methodologies in interdisciplinary sea ice research. These will include biology, ecology, sea ice geophysics and chemistry, oceanography, remote sensing and statistics. Discussions and lectures during the field course will broaden understanding of the complete scope of sea ice services provided to the ecosystem and humans in polar environments. This course will introduce students to different approaches to successfully address challenges of field research in the Arctic and Antarctic and allow students to design interdisciplinary field components of their research work. Students taking this course will receive training in applying modern state-of-the art tools and will also improve their writing and oral skills based on assignments given during the class. The class will provide students with a perspective of different and potentially conflicting uses of sea ice in Arctic environments. Students will be introduced to research approaches and methodologies that can provide stakeholders with data of relevance in the context of planning for and adapting to environmental and socio-economic change.

Instructors: Hajo Eicken,   Rolf Gradinger (UAF), Kunio Shirasawa (Hokkaido University) and contributing sea-ice experts (for details see below)

The instructors will prepare a detailed field handbook covering all modules. Students do not need to purchase any textbooks for this class. Suggested reading materials will be identified and made available in electronic form at no cost to the students at the latest one month prior to the start of the course. No additional library access is needed while being in the field. Students are expected to have read all field handbook instructions before traveling to Barrow. Students are also expected to be familiar with the UAF library electronic resources (such as web of science and electronic journal access) to access additional resources required for the final reports.

Course organization:

            All students will complete Module 1 individually before the onset of the field course.

           For the field course, the students will form interdisciplinary teams composed of between 3 and 5 students (depending on enrollment). Each team will complete all field-course modules. The reports on the different field course modules will then be prepared by groups of students with the appropriate disciplinary background, such that each student is at responsible for a final report on three field modules (in addition to Module 1 which will be completed prior to the course by every student). For example, one sub-group of students with a physical sciences background will team up to complete the final report for modules 2-4 (drawing on the data collected by all groups), while another sub-group with a biological background will be responsible for reporting on Modules 5, 6 and 8.

            During the field course, each group completing fieldwork will be accompanied by an instructor (and/or bear guard depending on weather, location and course progress). Laboratory work will be organized accordingly.

           

Grading policy

Grades will be based on reports (80 %) and course participation (20%) which would give us a bit of flexibility to recognize that somebody in a poor group may still be performing at a higher level.

Grades will be determined jointly by the instructor team based on student performance. We will use the following letter grade system:

F: <50%,

D: 50-60%,

C-: >60-63%,

C: >63-67%

C+:>67-70%

B-: >70-75%

B:>75-80%

B+:>80-85%

A-:>85-90%

A>:90-95%

A+:>95%

Students should be familiar with the UAF Honor Code (you find it in the catalog). Neither cheating, plagiarism nor fabrication will be tolerated. Any student found cheating during the exams or to have plagiarized or fabricated statements (including passages from web pages) will receive an automatic 'F' for the class . Any student found turning in a paper that has been used in another class will also receive an automatic 'F' grade for the class.

Learning disabilities : All disabilities have to be documented by UAF's Center for Health & Counseling, and instructors receive a formal letter requesting that we make accommodations for any student with disabilities. Please contact us as early as possible (not later than March 15, 2008) about your special requirements you might need. We will work with the UAF office of disabilities services (474-7043) to provide reasonable accommodation to students with disabilities. Note that the ability to conduct field work in harsh environments and transportation by snow machine will be essential to successfully complete the class.
