LMG9802: Underway Oceanographic Data from Antarctic Research Cruise

R/V Laurence M. Gould leg LMG9802 collected underway data during a research cruise starting and ending in Punta Arenas, Chile. The NSF-supported icebreaker conducts global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated on March 21, 1998.

Use Cases

• Analyze oceanographic conditions along the cruise track based on the description of underway data.
• Study biological and chemical changes in Antarctic waters based on the described research disciplines.
• Model physical oceanographic processes in the Southern Ocean based on the vessel's operational focus.
• Correlate underway measurements with other Antarctic datasets based on the described global change studies.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.

Limitations

• Last updated 1998-03-21 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.
