LMG9804: Underway Data from Antarctic Research Vessel Transit

R/V Laurence M. Gould leg LMG9804 collected underway data during a transit starting and ending in Punta Arenas, Chile. The NSF-supported research icebreaker operates year-round for the U.S. Antarctic Program, conducting studies in biological, chemical, physical, and oceanographic disciplines. This dataset was last updated on June 30, 1998.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on the time-series nature of the underway data.
• Study biological and chemical changes in Antarctic waters based on the described multidisciplinary scope.
• Model physical oceanographic processes for a specific vessel transit route based on the described geographic journey.
• Correlate environmental measurements with global change phenomena based on the dataset's stated purpose.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.

Limitations

• Last updated 1998-06-30 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.
