LMG1212: Underway Data from Antarctic Research Cruise

Underway data was collected during leg LMG1212 of the NSF-supported research icebreaker R/V Laurence M. Gould. The leg started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated by SCIOPS on November 23, 2012.

Use Cases

• Analyzing oceanographic conditions in Antarctic waters based on underway measurements.
• Studying global change impacts on polar marine biology and chemistry.
• Modeling physical oceanographic processes using time-series data from a research vessel.
• Correlating environmental variables across biological, chemical, and physical disciplines.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2012-11-23 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
