LMG0304A: Underway Data from Antarctic Research Icebreaker Laurence M. Gould

The NSF-supported research icebreaker Laurence M. Gould operates year-round in support of the U.S. Antarctic Program, carrying out global change studies in biological, chemical, physical, and oceanographic disciplines. This data set consists of underway data from leg LMG0304A, which started and ended at Punta Arenas, Chile. The dataset was last updated on June 4, 2003.

Use Cases

• Analyze physical oceanographic conditions in Antarctic waters based on underway data.
• Study biological and chemical changes in the Southern Ocean based on multidisciplinary global change studies.
• Model ship-track environmental transects based on the route from Punta Arenas, Chile.
• Correlate in-situ marine measurements with satellite observations based on the described global change research scope.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional quality control.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.

Limitations

• Last updated 2003-06-04 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.
