LMG0802: Underway Oceanographic Data from Antarctic Research Cruise

Antarctic and Southern Ocean data was collected during the LMG0802 research cruise of the R/V Laurence M. Gould, which operated in support of the U.S. Antarctic Program. The leg started and ended in Punta Arenas, Chile, and the dataset likely contains biological, chemical, physical, and oceanographic measurements. The data was last updated on March 16, -2008.

Use Cases

• Analyze temporal changes in oceanographic conditions based on underway data collection.
• Study biological and chemical interactions in Antarctic waters based on the multidisciplinary nature of the cruise.
• Model physical oceanographic processes in the Southern Ocean based on the described measurement disciplines.
• Correlate ship-track data with other regional observations based on the known voyage path.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional credibility.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic), indicating multidisciplinary scope.
• Specific voyage leg (LMG0802) and ports (Punta Arenas) are documented, providing clear operational context.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2008-03-16 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
