Seminar about the Quaternary Period (relatively recent past — spanning the past two million years) in order to gain a better understanding of the landscape, biota and climate of the present day. Quaternary studies are concerned with the historical dimension of the natural sciences. This seminar will range widely over diverse interdisciplinary subjects of Quaternary interest, such as paleoclimatology, paleobiogeography, vertebrate paleontology and sedimentology. (Prerequisite: Graduate standing or permission of instructor.) (3 + 0) Offered As Demand Warrants


GEOS 653     4 Credits
Palynology and Paleopalynology
(Stacked with GEOS 453)
Survey of the evolutionary record of palynomorphs and their uses in biostratigraphy and paleoclimatology. Focus on evolution of palynomorphs from Precambrian to the present and concurrent evolutionary developments of producing plants. Use of Quaternary palynofloras in reconstructing global climates. Labs involve collection of herbarium specimens, processing of fossil palynomorphs, study of type slides and a survey of palynofloras from each geologic period. Course fee: $60.

The principles and applications of active and passive microwave remote sensing with emphasis on spaceborne remote sensing of the Earth's atmosphere, land and oceans. The laboratory section will provide hands-on experience on special processing techniques, and the possibility of using these techniques for a student-defined term project in areas of geology, volcanology, glaciology, hydrology, environmental science, etc. (Prerequisite: GEOS 422 or equivalent. Next offered: 2008-09.) (2 + 2) Offered Alternate Spring


GEOS 658     3 Credits
Geoscience Applications of GPS and GIS (n)
(Stacked with GEOS 458)
Aspects of GPS data collection, including hands-on experience with different GPS units, differential GPS methods, real-time and post processing corrections. Concepts of Geographic Information Systems (GIS). Working with real-world data and software tools such as Excel spread sheets and ArcGIS, students will learn to organize and integrate multisource data, analyze spatial relationships and generate maps for digital and print media. Course is not available for audit. (Prerequisites: GEOS 225 or permission of instructor. Recommended: MATH 107X and 200X.) (2 + 3) Offered Spring


GEOS 663     4 Credits
Glacial and Periglacial Geology (n)
(Stacked with GEOS 463O)
Glaciers and their geological processes. Emphasizes recognition and understanding of glacial landforms, sediments, stratigraphic relations, implications for paleoclimatology and paleogeography. Includes non-glacial techniques and methods for interpreting Quaternary sediments. Course fee: $95. (Prerequisites: Graduate standing or GEOS 304. Next offered: 2008-09.) (3 + 3) Offered Alternate Fall
