Geomorphology of the Sabrina Coast Slope Seaward of Totten Glacier, East Antarctica

A 2020 study describes the geomorphology of the continental slope and rise between 112°E and 122°E, seaward of the Totten Glacier. The dataset, published in Marine Geology, details submarine canyons and ridges formed by sediment accretion and mass movement. It is sourced from Geoscience Australia Data and was last updated in March 2026.

Use Cases

• Classifying submarine canyon types based on thalweg shape (concave vs. convex) and sediment source.
• Modeling sediment transport pathways based on ridge asymmetry and canyon linkage to the shelf edge.
• Identifying potential coring sites for paleoclimate records based on described ridge sediment composition.
• Analyzing the continuum of mixed contourite-turbidite systems on the Antarctic margin as described in the study.

Strengths

• Study area is precisely defined between 112°E and 122°E longitude.
• Description provides detailed geomorphological analysis of distinct eastern and western regions.
• Data is associated with a peer-reviewed publication in Marine Geology (2020).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study area.
