Definition
Matusevich Glacier is a large outlet glacier located in East Antarctica, draining ice from the interior of the continent toward the coast.
Overview
The glacier lies in the region of Oates Land, flowing north‑eastward into the Matusevich Ice Shelf along the coast of the Southern Ocean. Satellite imagery and topographic maps indicate that the glacier extends for approximately 30–35 km (19–22 mi) in length, with a width that varies between 5 and 10 km (3–6 mi). The glacier is part of the East Antarctic Ice Sheet system and contributes ice mass to the adjacent ice shelf, which ultimately calves into the ocean.
Matusevich Glacier was first delineated from aerial photographs taken during the U.S. Navy’s Operation Highjump (1946–1947) and later mapped in greater detail by subsequent Soviet Antarctic Expeditions in the late 1950s. The glacier has been the subject of glaciological studies that monitor surface velocity, accumulation rates, and basal conditions, primarily using remote‑sensing techniques.
Etymology / Origin
The glacier was named by the Soviet Antarctic Expedition in honor of a Russian polar explorer bearing the surname Matusevich. Precise biographical details of the individual honored are not universally documented in publicly available sources; however, the naming follows the common practice of commemorating notable figures in polar exploration.
Characteristics
- Type: Outlet glacier feeding an ice shelf.
- Length: Approximately 30–35 km (19–22 mi).
- Width: 5–10 km (3–6 mi) (variable along its course).
- Flow direction: North‑eastward toward the Matusevich Ice Shelf.
- Surface velocity: Remote‑sensing measurements indicate flow speeds ranging from 200 to 400 m yr⁻¹, typical for East Antarctic outlet glaciers.
- Terminus: The glacier terminates at the Matusevich Ice Shelf, where ice is subsequently discharged into the Southern Ocean.
- Climate context: Situated in a polar desert environment, the glacier experiences extremely low annual precipitation and temperatures well below freezing year‑round.

Note: While the existence and basic geographical attributes of Matusevich Glacier are documented in scientific databases and cartographic sources, some specific historical details—particularly concerning the exact individual after whom the glacier was named—remain limited in publicly accessible records.
