Ice-Penetrating Radar Data Across Siple Coast grounding Lines
Entry ID: NSIDC-0474

[ Update this Record ]

Abstract: These data consist of ice-penetrating radar data collected on the ground across the grounding line near Siple Dome during the 2006 and 2007 Antarctic summer field seasons. Primarily, the data consist of low-frequency radar data (2MHz, resolution ~50 m) in order to observe deep internal layers and the ice-bed interface. In places, high-frequency (100 MHz, resolution ~1m) radar data also exist. Coincident kinematic GPS data was also collected to correct our radar data for topography along each profile. Radar profiles are typically ~20 km in length with the grounding line crossed centrally where possible.
