Sea Ice Brine Water Content and Diffusivity Measurements via NMR, 1997

Arctic sea ice cores were sampled to measure brine water content and liquid water diffusivity using Nuclear Magnetic Resonance (NMR). Measurements were taken at three points per depth in 200 mm steps over a 2.2-meter ice layer, with salinity and temperature data collected for comparison. The dataset was created by SCIOPS and last updated in November 1997.

Use Cases

• Modeling brine volume fraction in sea ice based on NMR-measured water content.
• Analyzing brine water mobility and transport properties based on diffusivity measurements.
• Comparing brine fraction estimates from NMR with those derived from salinity and temperature data.
• Studying the relationship between brine diffusivity and electrical conductivity for salinity estimation.

Strengths

• Measurements were taken at three points per depth over a 2.2-meter ice layer, providing a vertical profile.
• Data includes multiple correlated measurements: NMR water content, diffusivity, salinity, and temperature.

Limitations

• Last updated 1997-11-20 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
