Over four decades of historical and modern airborne radar sounding observations of the Ross Ice Shelf, spanning from 1971 to 2017. The dataset was created by a collaborative research project funded under the American Rescue Plan Act, involving three institutions and supporting student education. It contains processed and calibrated radar data from field campaigns in 1971-79 and 2011-17.
Use Cases
- Estimate basal melt rates by analyzing changes in ice-shelf thickness between 1971 and 2017.
- Calculate englacial temperature trends through attenuation analysis of radar data.
- Characterize changes in ice-shelf basal roughness and marine-ice formation using radiometric and scatterometric bed echo data.
- Improve geolocation of historical radar film by leveraging dense modern survey data for precise thickness comparisons.
- Analyze ice-shelf thickness, roughness, and englacial temperature to test hypotheses on decadal-scale basal melt rates.
Strengths
- Temporal coverage spans more than four decades, from 1971 to 2017.
- Data includes both historical (1971-79) and modern (2011-17) airborne radar campaigns for comparison.
- Project supports calibration and geolocation improvements for historical data.
Limitations
- Specific row count, column details, and file size are unknown.
- Data availability and direct access methods for the processed radar observations are not specified.
- Geographic coverage is limited to the Ross Ice Shelf region of Antarctica.
