- Abstract
The article discusses the investigation of glacial retreat in Antarctica. Many questions concerning the glacial retreat have inspired middle school students to design a directed inquiry by simulating glacial retreat. The students have melted glaciers, changed the water level and salinity of the Southern Ocean, and examined alterations to the Antarctic food web. Scientists have observed that the salinity of coastal water decreases as glaciers rapidly melt, causing a shift in the Antarctic phytoplankton community from diatoms to cryptophytes. The shift is unfavorable for krill to feed on efficiently, and may be of low nutritional value. These will largely affect the Antarctic food web.
