The Matusevich Glacier flows toward the coast of East Antarctica, pushing through a channel between the Lazarev Mountains and the north-western tip of the Wilson Hills.[1] Constrained by surrounding rocks, the river of ice holds together. But stresses resulting from the glacier’s movement make deep crevasses, or cracks, in the ice. After passing through the channel, the glacier has room to spread out as it floats on the ocean. The expanded area and the jostling of ocean waves prompts the ice to break apart, which it often does along existing crevasses. Matusevich Glacier does not drain a significant amount of ice off of the Antarctic continent, so the glacier’s advances and retreats lack global significance.[1] Like other Antarctic glaciers, however, Matusevich helps glaciologists form a larger picture of Antarctica’s glacial health and ice sheet volume.

Matusevich Glacier Tongue

Matusevich Glacier Tongue (69°5′S 157°15′E / 69.083°S 157.25°E / -69.083; 157.25) is a glacier tongue about 18 nautical miles (33 km) long which is the broad seaward extension of the Matusevich Glacier. The Magga Dan, vessel of the ANARE (Australian National Antarctic Research Expeditions) led by Phillip Law, sailed around the tongue, February 21, 1959, at which time the seaward extremity was determined to be floating in 300 fathoms of ocean.
