LMG1302: Underway Data from Antarctic Research Cruise

Antarctic waters are the focus of this dataset from leg LMG1302 of the R/V Laurence M. Gould icebreaker. The data was collected in support of the U.S. Antarctic Program for global change studies across biological, chemical, physical, and oceanographic disciplines. The cruise leg started and ended in Punta Arenas, Chile, and the dataset was last updated in March 2013.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on underway data collection.
• Study biological and chemical changes in Antarctic waters based on the multidisciplinary research focus.
• Model physical oceanographic processes in the Southern Ocean based on the cruise's operational area.
• Correlate environmental variables for climate change research based on the global change studies mentioned.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional credibility.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2013-03-04 23:59:59.999000; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
