Antarctic Sea Ice Mass Balance Measurements from 2007 and 2009 Drift Program

Fall 2007 and spring 2009 Antarctic sea ice data from the SIMBA program, collected during the Nathaniel B. Palmer icebreaker drift with a buoy network. Measurements include ice thickness, temperature profiles, large-scale deformation, and other sea ice characteristics. The dataset is provided by NASA.

Use Cases

• Modeling sea ice mass balance using ice thickness and snow depth measurements.
• Analyzing thermal properties of sea ice through temperature profile data.
• Studying ice deformation and stress from large-scale deformation records.
• Investigating snow-ice interactions using snow classification and density data.

Strengths

• Data collected during two distinct seasons (fall 2007 and spring 2009) provides seasonal comparison.
• Multi-instrument measurements from a coordinated drift program and buoy network.
• Dataset is hosted by NASA and appears on multiple platforms, indicating established use.

Limitations

• Specific row counts, file sizes, and column names are not provided by any source.
• Conflicting last updated dates: datagov lists 2026-03 12, while nasa_earthdata lists 2009-03-19.
• License is specified as 'other-license-specified' on datagov but is 'None' on nasa_earthdata.
