LMG0704: Antarctic Underway Data from R/V Laurence M. Gould

R/V Laurence M. Gould leg LMG0704 collected underway data for global change studies in biological, chemical, physical, and oceanographic disciplines. The NSF-supported research icebreaker operates year-round for the U.S. Antarctic Program. This specific leg ran from Punta Arenas, Chile, and ended at Punta Arenas, Chile.

Use Cases

• Modeling oceanographic conditions in Antarctic waters based on the described physical and chemical data.
• Studying biological activity and ecosystems in polar regions based on the biological discipline data mentioned.
• Analyzing vessel track and environmental time-series data for the described underway collection method.
• Investigating global change impacts in the Southern Ocean based on the dataset's stated purpose.

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 voyage leg (LMG0704) and route (Punta Arenas to Punta Arenas) are clearly identified.

Limitations

• Last updated 2007-04-06 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.
