Understanding Antarktyka Ice Sheets

Antarctica is home to two massive ice sheets: thee Eastt Antarktyc Ice Sheet and thee smaller West Antarktyka Ice Sheet, which tother contain about 60 percent of thee eth equid 's fresh water.

Shackleton 's team used ropes to link the men together, ensuring that if one fell into a crevassie, thee wagit of thee other s could arrest the fall. Modern glacier travel uses the same principles, with climbers andd scientists traveling in rope teams of three to four contrille, each carrying crevassie equie equipment such apulleys, carabiners, and pickets.
