Aerogeophysical characterization of Titan Dome, East Antarctica, and potential as an ice core target

Abstract. Based on sparse data, Titan Dome has been identified as having a higher probability of containing ice that would capture the middle Pleistocene transition (1.25 to 0.7 Ma). New aerogeophysical observations (radar and laser altimetry) collected over Dome, located about 200 km from South Pole within East Antarctic Ice Sheet, were used characterize region (e.g., geometry, internal structure, bed reflectivity, flow history) assess its suitability paleoclimate core site. The radar coupled with an available chronology enabled tracing dated reflecting horizons throughout region, which also served constraints basal age modeling. results survey revealed new topographic detail better constrain topographical location differs between community datasets. is not expected be relevant study due combination past fast dynamics, likely being too young, temporal resolution coarse if 1 Ma exist.
