Geomorphology of the Continental Slope Seaward of Totten Glacier, East Antarctica

Geoscience Australia Data provides a dataset describing the submarine geomorphology of the continental slope and rise seaward of the Totten Glacier and Sabrina Coast, East Antarctica (112°E-122°E). The data, published in Marine Geology in 2020, details a suite of submarine canyons and ridges formed by mixed contourite-turbidite systems. It characterizes two distinct areas with differing canyon thalweg profiles, ridge asymmetry, and sediment sources from the glacier and ocean currents.

Use Cases

• Classifying submarine canyon types based on thalweg profile (concave vs. convex) and linkage to shelf edges.
• Modeling sediment transport and deposition processes for mixed contourite-turbidite systems.
• Identifying potential coring sites for paleoclimate records based on ridge morphology and sediment accretion patterns.
• Analyzing the geomorphological impact of ice drainage basins like the Moscow University Ice Shelf on slope features.

Strengths

• Dataset is derived from a peer-reviewed study published in Marine Geology (Volume 427, 2020).
• Description provides a detailed geomorphological analysis of two distinct areas within the study region.
• The data links specific ridge and canyon features to sediment sources from the Totten Glacier and along-margin transport.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study area (112°E-122°E).
