Ice Core Physical Properties for Brittle Behavior Prediction

EAGER project data investigates the physical properties of ice cores to predict brittle ice behavior. The project is a collaboration between Northern Arizona University, the National Science Foundation Ice Core Facility, and Pennsylvania State University, utilizing existing ice-core data from multiple sites. The project description was last updated in January 2024.

Use Cases

• Predict brittle ice behavior from physical properties like bubble size and c-axis fabric to guide drilling site selection.
• Analyze correlations between site characteristics and measured ice brittleness across multiple ice-core locations.
• Model the onset of brittle ice using targeted investigations of various ice physical properties from existing core samples.

Strengths

• Data leverages existing ice cores from several previously drilled Antarctic sites, avoiding the need for new fieldwork.
• Research focuses on specific, measurable drivers of brittleness: bubble size and c-axis fabric.

Limitations

• The exact sample size, row count, and specific data columns are not provided in the description.
• Data is derived from a 'high-risk, low-cost' exploratory project, which may indicate preliminary or incomplete findings.
• Geographic coverage is limited to specific, pre-existing ice-core sites, which may not be fully representative.
