LMG0202: Antarctic Icebreaker Underway Data from 2002 Transit

Antarctic research vessel R/V Laurence M. Gould collected this underway data during its LMG0202 transit leg in 2002. The leg started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated on April 2, 2002.

Use Cases

• Analyze vessel transit patterns and environmental conditions based on the underway data collection method.
• Study correlations between physical oceanographic parameters and biological/chemical measurements mentioned in the description.
• Model baseline conditions for the Antarctic region during the 2002 research season.
• Validate or calibrate other Southern Ocean datasets using this direct observational record.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating authoritative collection.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.
• Provides a specific temporal snapshot from a completed research leg (LMG0202).

Limitations

• Last updated 2002-04-02 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.
