Geomorphology of the Sabrina Coast Continental Slope and Rise, East Antarctica

A suite of submarine canyons and ridges seaward of the Totten Glacier reveals distinct sediment transport processes. The study area, spanning 112°E to 122°E, is divided into eastern and western zones with differing canyon thalweg shapes and ridge formation mechanisms. This dataset, published in Marine Geology in 2020, likely contains geospatial features describing these underwater landforms and their inferred sedimentary history.

Use Cases

• Classifying submarine landform types based on described geomorphological features like concave vs. convex thalwegs.
• Modeling sediment transport pathways based on the described mechanisms of turbidity currents and contourite formation.
• Identifying potential coring sites for paleoclimate records based on the description of ridges as prime sedimentary archives.
• Comparing mixed contourite-turbidite systems across the Antarctic margin using the described continuum of geomorphology.

Strengths

• Dataset is associated with a peer-reviewed publication in Marine Geology (Volume 427, 2020).
• Description provides a detailed, process-oriented analysis of distinct geomorphological regions (eastern vs. western study area).
• The geographic scope is precisely defined as the area from 112°E to 122°E seaward of the Totten Glacier.

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 of the Sabrina Coast.
