The Antarctic ice sheet changes in size over the course of a year. When it is summer in the southern hemisphere, the ice sheet decreases in size. As the ice sheet melts, it releases fresh water into the ocean. In the southern winter (our summer), the ice refreezes, drawing fresh water out of the surrounding ocean, leaving the salt behind. These seasonal changes in the ice sheet are examined in this activity, utilizing satellite imagery.
