GEOS 615, Sea-ice geophysics (3 CR) GEOS 615 Overview Labs Project assignment Syllabus & Notes GEOS 615, Sea-ice geophysics (3 CR), Fall 2006 Time & place: M 9-10.30am NS 235 (Natural Sciences Building), W 9-10.30am NS 235 (tentative schedule and location, potentially subject to change!) FIRST CLASS: W Sep 6, 9-10.30am (at this meeting we will decide on the class hours and location for the rest of the semester, please get in touch with instructor if unable to attend) Instructor: Hajo Eicken, Geophysical Institute, UAF e-mail: [email protected] Phone: 474-7280 Office: West Ridge Research Building (WRRB) 104E (office hours: ad-hoc/by appointment) Grading scheme: Final exam: 30 % Mid-term exam: 15 % Lab exercises: 25% (two exercises on sea-ice albedo and ice growth and remote sensing, requiring a lab report, each weighted equally) Project assignment: 30 % (includes presentation and written report of <5 pages length) In regards to the class project, the official start of the International Polar Year 2007-2009 (www.ipy.org) is only just over half a year away. To get ready for this exciting opportunity, the class projects should in some form address the history of sea ice through time from the first IPY (1882/83) through to today, a day and age where arguably, northern hemisphere sea ice extent is at the lowest it has been observed in the historical record. While students are encouraged to pursue their own project ideas, a number of interesting potential project topics (and advice from experts in historical environmental observations) will be supplied. Required reading: To be assigned (incl. lecture notes and selected papers); course does not have required text; however, students are encouraged to consult primary references listed below (on hold for duration of semester at Keith Mather Library-GI/IARC, some also available from instructor).
