LMG0204B: Underway Oceanographic Data from Antarctic Research Icebreaker

R/V Laurence M. Gould collected this underway data during leg LMG0204B, which started and ended at Punta Arenas, Chile. The NSF-supported icebreaker operates year-round for the U.S. Antarctic Program, conducting studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated on July 29, 2002.

Use Cases

• Analyzing oceanographic conditions along the vessel's transit route based on the description of physical and chemical disciplines.
• Studying temporal changes in marine environments based on the time-series nature of underway data.
• Correlating biological observations with physical oceanographic data based on the multidisciplinary research scope.
• Modeling ship-based data collection for Antarctic research programs based on the described operational support role.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.
• Provides a specific temporal reference point with a last update date of 2002 -07-29.

Limitations

• Last updated 2002-07-29 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.
