LMG9809: Underway Data from Antarctic Research Cruise

R/V Laurence M. Gould leg LMG9809 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, with this specific leg starting and ending in Punta Arenas, Chile. Data was last updated in November 1998.

Use Cases

• Analyzing oceanographic conditions in Antarctic waters based on the described physical and chemical data.
• Studying temporal changes in biological activity based on the biological discipline data mentioned.
• Modeling ship-track environmental measurements based on the underway data collection method.
• Investigating historical baseline conditions for climate change studies based on the global change research focus.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional rigor.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Specific cruise leg (LMG9809) and route (Punta Arenas to Punta Arenas) are clearly documented.

Limitations

• Last updated 1998-11 20 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.
