LMG1108: Underway Data from Antarctic Research Cruise, 2011

R/V Laurence M. Gould leg LMG1108 collected underway data for global change studies in biological, chemical, physical, and oceanographic disciplines. The NSF-supported icebreaker operates year-round in the Antarctic, with this specific leg starting and ending in Punta Arenas, Chile. The dataset was last updated in October 2011.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on the underway time-series data.
• Study biological and chemical changes in Antarctic waters based on the multidisciplinary data collection.
• Model physical oceanographic processes in the Southern Ocean based on the cruise-based measurements.
• Investigate global change impacts on polar regions based on the integrated biological, chemical, and physical data.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides a continuous time-series record from a specific research cruise leg.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2011-10-01 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
