Before you begin retrieving data, be sure your SEE Image software is installed on your computer.

RETRIEVING DATA

Data for the tutorial and exercises have been put into individual folders and compressed for faster downloading. To retrieve the desired data folder, click on the appropriate link below. When the download is complete and the archive is unpacked, which will occur automatically, you'll see three new icons on your desktop for each set of data you downloaded. Two are document icons that will the file name extensions .sea.hqx and .sea. The third is a folder icon. (In case you don't see the folder icon, just double click the .sea file icon on your desktop.) When you've completed this step you may trash the .sea.hqx and .sea files. Drag that folder into the "Sea_Ice" folder inside the "Data" folder in your SEE Image folder.
NOTE: It is important to place your data folders in the correct place in order to follow the step-by-step instructions given in the tutorial and exercises, where navigational paths are shown as follows:

DATA FOR FURTHER STUDY

Once you're comfortable with the concepts presented in the exercises and have mastered the software, explore the entire Polar Sea Ice data set (psi_entire) more fully. After all, you have nearly 20 years of monthly mean, maximum, and minimum sea ice images for each pole right here on this Web site. Complete the same exercises using other images or sequcnes of images.

The National Snow and Ice Data Center in Boulder, CO, is the source for information and data about high latitude Earth science, including sea ice. The Web site is http://www.nsidc.noaa.gov.

SATELLITE DATA INFORMATION

Information on the satellite data is included in Part 2 of the Scientific Background for Studying Polar Sea Ice Processes lecture in the Class Resources component of this module.
