East Antarctic Interior Structure Inventory
East Antarctica contains a diverse collection of buried geological structures identifiable through radar, gravity, magnetic, and seismic datasets.
Regional Geological Context
Important regions include Dome A, Dome C, Wilkes Land, Aurora Subglacial Basin, Recovery Basin, Gamburtsev Mountains, and the East Antarctic Craton.
Research institutions associated with Antarctic geophysical investigations include British Antarctic Survey, Cambridge, United Kingdom; Australian Antarctic Division, Tasmania, Australia; and National Science Foundation Antarctic Program, United States.
Observation
Current datasets reveal extensive buried topography, structural boundaries, crustal heterogeneity, and regional-scale geophysical anomalies.
Constraint Analysis
Many East Antarctic structures remain only partially constrained due to limited direct geological exposure.
Open Questions
Which East Antarctic features represent the highest-priority targets for future geological and geophysical investigation?
