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

A study area from 112°E to 122°E seaward of the Totten Glacier and Sabrina Coast in East Antarctica. The dataset, published in Marine Geology in 2020, describes submarine canyons and ridges formed by mixed contourite-turbidite systems, indicating sediment accretion and mass movement processes. These features are proposed as prime locations for sampling sedimentary records of glacier-ocean interaction.

Use Cases

• Classifying submarine geomorphological features based on described canyon and ridge morphologies.
• Modeling sediment transport pathways based on descriptions of pelagic, hemipelagic, and turbidity current deposits.
• Identifying potential coring sites for paleoclimate records based on the described long-lived depocenter and ridge accretion processes.
• Analyzing the continuum of mixed contourite-turbidite systems on the Antarctic margin as described in the study.

Strengths

• Study area is precisely defined from 112°E to 122°E seaward of the Totten Glacier.
• Description provides a detailed geomorphological analysis differentiating eastern and western canyon-ridge systems.
• Dataset is associated with a peer-reviewed publication in Marine Geology (Volume 427, 2020).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data format is listed as HTML, which may not be a standard geospatial data format.
