Petermann is a tidewater glacier whose ice extends into the ocean as a floating ice tongue.

Key Terms

Calving → breaking off of large blocks of glacier ice.

Ice tongue → floating extension of glacier ice into water.

Climate Significance

Glacier changes can indicate:

  • Arctic warming
  • Ocean temperature changes
  • Ice-sheet dynamics
  • Sea-level implications.

Key Pointer

Petermann → Greenland → Arctic → ice tongue → calving
