LMG1709: Underway Oceanographic Data from Antarctic Research Cruise

Leg LMG1709 data was collected in 2017 by the NSF-supported research icebreaker R/V Laurence M. Gould. The dataset consists of underway measurements from a round-trip voyage between Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. It was last updated on October 17, 2017.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on underway data collection.
• Study biological and chemical changes in Antarctic waters mentioned in the description.
• Correlate physical oceanographic measurements with global change phenomena.
• Model ship-track environmental transects for the specified research leg.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides a specific temporal snapshot from leg LMG1709 in 2017.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2017-10-17 23:59:59.999000; freshness should be verified.
• Row count and file formats are unknown, which may limit suitability assessment.
