West Antarctic field and modeling data investigates the potential reactivation of Kamb Ice Stream. The project collected observations of bed properties, internal radar reflectors, surface strain rates, and velocity changes using Ice-Penetrating Radar and GPS. Research was conducted by SCIOPS, with data last updated in December 2005.
Use Cases
- Model ice stream reactivation by analyzing downstream migration rates of the bulge-trunk transition.
- Predict near-future ice stream evolution over 100-1000 years using numerical models informed by field observations.
- Analyze ice diversion toward Whillans Ice Stream using surface strain rate and velocity change data.
- Study controls on ice stream stoppage by examining bed properties and internal radar reflector geometry.
Strengths
- Focuses on a specific, critical transition zone (bulge-to-trunk) for detailed process understanding.
- Combines field observations (radar, GPS) with numerical modeling for a multi-method approach.
Limitations
- Data is temporally stale, last updated in 2005, limiting analysis of recent changes.
- Specific row counts, column details, and sample sizes from the field component are unknown.
- Geographic scope is limited to a single ice stream in West Antarctica.
Provenance
- Source
- SCIOPS via NASA EarthData.
- Collection Method
- Field observations using Ice-Penetrating Radar and differential GPS, combined with numerical modeling.
- Time Range
- Modeling covers near-future scenarios (~100-1000 years). Field observation period is unspecified.
- Freshness
- 2005-12-26
- Geography
- Kamb Ice Stream (formerly Ice Stream C), West Antarctica, specifically the bulge-trunk transition near camp UpC.
