LMG1809: Antarctic Research Cruise Underway Data from the R/V Laurence M. Gould

The NSF-supported research icebreaker Laurence M. Gould collected this underway data during leg LMG1809, which started and ended in Punta Arenas, Chile. The dataset supports global change studies in biological, chemical, physical, and oceanographic disciplines in the Antarctic region. The data was last updated on November 3, 2018.

Use Cases

• Analyze time-series patterns of oceanographic conditions based on underway data collection.
• Model biological or chemical changes in Antarctic waters based on the described global change studies.
• Correlate physical oceanographic measurements with other Antarctic climate datasets.
• Study vessel-based data collection methodologies for remote polar research.

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 defined research leg (LMG1809).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2018-11-03 23:59:59.999000; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
