LMG1103: Underway Oceanographic Data from Antarctic Research Cruise

The R/V Laurence M. Gould LMG1103 dataset contains underway data collected by the NSF-supported research icebreaker. This leg of the vessel's operations started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The data was last updated on April 8, 2011.

Use Cases

• Analyzing temporal patterns in oceanographic conditions based on underway data collection.
• Studying biological and chemical changes in Antarctic waters mentioned in the description.
• Correlating physical oceanographic measurements with other regional climate datasets.
• Modeling vessel-track environmental data for time-series analysis.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating institutional support.
• Covers multiple scientific disciplines including biological, chemical, physical, and oceanographic studies.
• Platform tags specify the data is tabular and a time-series, providing format context.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2011-04-08 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
