The thermal conductivity and diffusivity of first year sea ice measured as a temperature d

McMurdo Sound, Antarctica, is the location for this dataset of temperature-depth profiles measured through developing sea ice during winter months. The data, recorded hourly and retrieved biweekly, was collected by SCIOPS to calculate thermal conductivity and diffusivity, excluding solar radiation effects. The measurements can be used to determine the rate of ice growth and reconstruct the formation history of the sea ice.

Use Cases

• Modeling sea ice growth rates based on recorded thermal information and temperature profiles.
• Calculating thermal conductivity and diffusivity of first-year sea ice based on heat flow measurements.
• Reconstructing the formation history of seasonal sea ice based on combined growth and thermal data.

Strengths

• Temperature profiles were measured with a 10cm vertical resolution.
• Data was logged hourly, providing a high temporal resolution.
• Measurements were designed to exclude confounding thermal radiation from sunlight.

Limitations

• Last updated 1999-10-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
