LMG0804: Underway Oceanographic Data from Antarctic Research Cruise

NSF-supported research icebreaker Laurence M. Gould collected this underway data during leg LMG0804, which operated in support of the U.S. Antarctic Program. The leg started and ended at Punta Arenas, Chile, focusing on global change studies across biological, chemical, physical, and oceanographic disciplines. Data was last updated on April 23, 2008.

Use Cases

• Modeling oceanographic conditions in Antarctic waters based on the described underway data collection.
• Calibrating benthic foraminifera as paleoenvironmental proxies based on the research cruise's stated purpose.
• Analyzing seasonal impacts on marine biology as suggested by the dataset's title and research focus.
• Studying global change across multiple disciplines (biological, chemical, physical, oceanographic) using the integrated cruise data.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Specific cruise leg (LMG0804) and ports (Punta Arenas, Chile) are documented, providing clear voyage context.

Limitations

• Last updated 2008-04-23 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.
