NASA Earthdata hosts a dataset from a project by AMD_USAPDC to revise models of glacier-ocean interactions. The project uses laboratory experiments to study melt rates influenced by ice roughness, geometry, ocean turbulence, and density stratification. Data includes high-resolution velocity, density, and temperature measurements near the ice-ocean interface, with a last updated date of 2026-04-30.
Use Cases
- Validating and improving numerical models of glacier evolution based on laboratory-derived melt rate data.
- Analyzing the relationship between subglacial meltwater plumes and ice melt rates as described in the experimental program.
- Studying the effects of ice roughness and geometry on ocean boundary layer dynamics.
- Investigating the impact of ocean density stratification and turbulence on heat transfer at the ice-ocean interface.
Strengths
- Data is gathered using high-resolution, laser-based optical techniques (particle image velocity and laser-induced fluorescence).
- Experiments are conducted using refractive-index matching techniques to eliminate measurement bias.
- Experiments are run in a climate-controlled cold room to mimic field conditions.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
