Description
EAGLE/ICECAP II data contains geolocated, time-registered aerogeophysical observations collected over Antarctica during the 2015/16 and 2016/17 field seasons. The dataset includes GPS, raw serial packet data, radar records, gravimeter readings, and camera images. It was produced by the International Collaborative Exploration of the Cryosphere through Airborne Profiling (ICECAP) collaboration, funded by the US National Science Foundation and supported by the Australian Antarctic Division.
Use Cases
Map subglacial topography and bedrock features by analyzing raw radar records and gravimeter data.
Calibrate sensor readings and validate flight paths using the time-registered GPS and raw serial packet data.
Correlate surface features with subsurface measurements by fusing camera images with geophysical sensor data.
Develop time-series models of ice sheet changes using the temporally registered observations from two consecutive field seasons.
Strengths
Data from two consecutive Antarctic field seasons (ICP7 and ICP8) provides temporal comparison.
Includes multiple sensor modalities (GPS, radar, gravimeter, camera) for data fusion.
Data is geolocated and time-registered, enabling precise spatial and temporal analysis.
Follows established formats from the predecessor ICECAP/OIB project, aiding in continuity.
Limitations
Specific row counts, file sizes, and detailed column definitions are not provided.
Data is from 2015-2017 and may not reflect current Antarctic conditions.
The multimodal nature requires specialized tools for processing radar, images, and serial data together.
