ASSIGNMENT A sampling of the spatial characteristics of glaciers in the lower 48 states.
The intent of this assignment is to acquaint you with the spatial characteristics of a sampling of glaciers within the lower 48 United States and to help you make the connection with spatial patterns in climate. Because of the size of the image files (1.7 - 3.2 Mb) you will be using, I recommend you do this assignment at a computer on campus.
1. Eight glacierized areas have been scanned:
2. Choose 10 glaciers in each state (50 glaciers) that, in your opinion, roughly represent the spatial characteristics of the glaciers in that quadrangle. Spatial characteristics include area, orientation, elelvation, etc. Make a table for each quadrangle (EXCEL can help here) and include the following columns of data in order: Glacier
Minimum Maximum Average
Altitude Orientation
Not all glaciers will have a name, if not, please include the peak the glacier is on if possible. Calculate the average altitude from the average of the minimum and maximum altitude. The range is the difference between minimum and maximum. Estimate the orientation according to the 8 cardinal points of the compass (N, NE, E, etc) Include the approximate latitude and longitude of the center of each quadrangle from which the glacier data has been collected.
3. Make 3 plots: a) the average altitude of all the glaciers for a north-south transect along the Pacific Coast (WA-OR); b) the same for the inland north-south inland transect (MT, WY, CO); c) a west to east transect (WA-MT). Note, include in this plots
the range of each glacier. Use the plotting symbol 4. Discuss the differences in these elevations according to variations in climate for each region. Consult the library and search the web for data to support your discussion of climate. Since there are no climate stations near the glaciers do the best you can with the climate data you acquire. Include in the discussion a section on orientation of the glaciers in each region. Can you figure out a way to plot that data? 5. FINAL PRODUCT: Turn in the results of steps 2, 3, and 4 in the form of a report. Outline the report as follow:
----------------------------------------------- You may work with others on the report, but your writing, figures, tables, etc, must be your one work. The report will be typed in 12pt font, double spaced, and multiple pages stapled together. |
