LMG1408: Underway Oceanographic Data from Antarctic Research Cruise

Leg LMG1408 of the R/V Laurence M. Gould collected underway data for global change studies in biological, chemical, physical, and oceanographic disciplines. The cruise started and ended at Punta Arenas, Chile, and the dataset was last updated in September 2014. The data is supported by the NSF and managed by the U.S. Antarctic Program.

Use Cases

• Analyze temporal changes in oceanographic conditions based on the underway data collection.
• Study biological and chemical properties in Antarctic waters mentioned in the description.
• Model physical oceanographic processes using continuous measurements from a research vessel.
• Correlate environmental variables for global change research as described.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, the R/V Laurence M. Gould.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides continuous underway measurements from a specific Antarctic research leg (LMG1408).

Limitations

• Last updated 2014-09-27 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
