LMG0906A: Underway Data from Antarctic Research Icebreaker Voyage

R/V Laurence M. Gould leg LMG0906A collected underway data for global change studies in biological, chemical, physical, and oceanographic disciplines. The NSF-supported icebreaker operates year-round for the U.S. Antarctic Program. This specific voyage started and ended at Punta Arenas, Chile.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on underway data collection mentioned in the description
• Study biological and chemical changes in Antarctic waters based on the multidisciplinary research focus
• Correlate physical ocean data with global change models based on the dataset's stated purpose
• Map the route and environmental parameters of a specific Antarctic research voyage based on the leg details

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting controlled collection
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis
• Specific voyage leg (LMG0906A) and ports (Punta Arenas) are clearly identified

Limitations

• Last updated 2009-07-01 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
