A 2023/24 ground-based gravity and GNSS dataset collected at nine sites along a ~14 km transect across the Denman Glacier system. The survey was conducted along an existing ICECAP airborne flight line, enabling direct comparison between ground and airborne observations. The data is provided by the Australian Ocean Data Network.
Use Cases
- Validate airborne gravity measurements based on coincident ground-based observations.
- Analyze glacier mass changes based on precise ground-based gravity data.
- Calculate precise station positions and ellipsoidal heights based on GNSS observations.
- Study the Denman Glacier system's geophysical properties based on a transect across its features.
Strengths
- Data collected along a ~14 km transect enabling spatial analysis.
- Coincident GNSS observations provide precise positioning.
- Survey aligns with an existing ICECAP airborne flight line for direct comparison.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific transect.
