LMG1311: Underway Data from Antarctic Research Icebreaker Voyage

R/V Laurence M. Gould is a National Science Foundation-supported icebreaker conducting year-round global change studies in the Antarctic. This dataset contains underway measurements from leg LMG1311, which sailed from and returned to Punta Arenas, Chile. The data likely supports biological, chemical, physical, and oceanographic research for the U.S. Antarctic Program.

Use Cases

• Analyzing temporal patterns in oceanographic conditions based on underway data collection.
• Studying biogeochemical cycles in Antarctic waters based on the described chemical and biological disciplines.
• Correlating physical oceanographic measurements with biological observations for climate change research.
• Modeling ship-track environmental data for spatial analysis of the Southern Ocean.

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

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
