Brief course description and rationale
This is a course for graduate-level students that offers a practical 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 in the polar regions and the transdisciplinary importance of the ice cover in the climate system.
The course is organized in such a way 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. An effort will be made to entrain students from Ilisagvik College in the course activities and include a Native Alaskan ice-knowledge component.
Student Learning Outcomes:
The goal of this course is to introduce graduate students to the methodological approaches for interdisciplinary sea ice research. These approaches will include biology, ecology, sea ice physics and chemistry, oceanography, remote sensing and statistics. Discussions and lectures during the field course will broaden the scope into understanding of the complete scope of sea ice services to the ecosystem and humans in ice-covered waters. This course will enhance the awareness of challenges related to conduct research in the Arctic and the implications of Arctic warming in Alaskan waters. Students taking this course will receive training in applying modern state-of-the art tools in the Arctic and will also improve their writing and oral skills based on assignments given during the class.
Registration: Prior to registration at the UAF summer sessions website (www.uaf.edu/summer/), students are asked to send their CV and a 1-page statement indicating how this field course will fit into their research and career plans to email@example.com. The instructors will evaluate these documents to decide about participation if the course is oversubscribed. Deadline for submission of these documents is Friday, March 15, 2013. Students will then be notified by April 1 at the latest about their inclusion in the course.
All students will complete 9 different teaching modules that involve a wide range of field work, sample processing in the lab, presentations and lectures. Module descriptions can be found at:
All students will complete Module 1 individually before the onset of the field course.
For the field course, the students will form 4 interdisciplinary teams composed of between 3 and 5 students (depending on enrollment). Each team will complete all of the field-course modules (module 2 to 9). Data analysis and module reports will be completed such that each student is part of a small group that is responsible for 2 of the reports for modules 2-9.
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.
All students will participate in the following nine modules. Detailed descriptions of the modules will be posted on the class specific website and be made available to the students latest one month prior to the class.
Module 1, Introduction to field program design, including use of remote sensing of sea ice properties and processes
Seasonal cycle of sea-ice reflectance (albedo) and surface temperature based on AVHRR data analysis; synthetic aperture radar (SAR) backscatter signatures of sea ice; use of remote-sensing data in designing field measurement programs; regional upscaling from field measurements through remote sensing
Module 2, Sea ice and snow thickness and morphology
Direct measurements of ice thickness; electromagnetic induction measurements of apparent conductivity and derivation of sea-ice thickness; ice morphology (level, rafted, ridged); snow depth and snow property measurements
Module 3, Ice-core and in-situ measurements of basic sea-ice physical properties
Ice core drilling and sampling; in-situ measurements of ice temperature, ice electrical conductivity, measurement of ice strength in-situ with borehole jack strength tests and ice engineering properties

Those enrolled in this class are subject to the Student Code of Conduct as outlined in University Regents' Policy on Student Rights and Responsibilities.Students should be familiar with the UAF Honor Code. Neither cheating, plagiarism nor fabrication will be tolerated. Any student found 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. Students are expected to participate in all modules outlined above, be on time, and be active members of their working groups.
Special needs: Students with learning or other disabilities who may need special course accommodations are encouraged to visit the Disabilities website and make an appointment with the Office of Disability Services (474-5655). Please meet with the instructors (not later than April 1, 2013) so that the appropriate accommodations and supports to assist in meeting the goals of the course can be made in collaboration with the Office of Disability Services. Note that the ability to conduct field work in harsh environments and transportation by snow machine will be essential to successfully complete the class.
