Going Further

Variations

The National Snow and Ice Data Center (NSIDC) has many opportunities for further exploration. Here are a few ideas to try.

  • Examine the sea ice data downloaded in this lesson for variations in concentration.
  • Examine sea ice in the Antarctic Regioncompare fluctuations and seasonality. Use either the online animations or access the data sets from the ftp site referred to in the chapter.
  • Add wind pattern data to the sea ice data and explore relationships between these two factors.

Other Data

Antarctic Sea Ice data can be also be downloaded from the NSIDC website. Antarctic sea ice is in the same directories, but it is in the "South" folders.

An important difference is when you import the Antarctic fields: the images are 316 by 332 pixels instead of the values used for the Arctic.

Other Tools

Google Earth software can be used for visualization of this data.
Data sets in KMZ format (for Google Earth) can be downloaded at NSIDC Data on Virtual Globes: Google Earth

Sea Ice data can be viewed and animated online using the NSIDC Sea Ice Animation Tool

Case Studies with Tool

Other EET chapters that utilize ImageJ as a tool and satellite imagery as a data source include the following:
