LMG9806: Underway Oceanographic Data from Antarctic Research Vessel Transit

R/V Laurence M. Gould leg LMG9806 collected underway data during a transit starting and ending in Punta Arenas, Chile. The NSF-supported icebreaker conducts year-round global change studies in biological, chemical, physical, and oceanographic disciplines. The data was last updated on August 2, 1998.

Use Cases

• Analyzing physical oceanographic conditions during a vessel transit based on the description of physical discipline data.
• Studying chemical properties of Antarctic waters based on the mention of chemical discipline studies.
• Investigating biological phenomena in polar regions based on the description of biological discipline research.
• Modeling oceanographic time series for climate studies based on the platform tags indicating time-series 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.
• Provides a specific temporal snapshot from a completed research leg (LMG9806).

Limitations

• Last updated 1998-08-02 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.
