LMG1109: Underway Oceanographic Data from Antarctic Research Cruise

R/V Laurence M. Gould collected this data during a 2011 Antarctic research leg, LMG1109, which began and ended in Punta Arenas, Chile. The NSF-supported icebreaker operates year-round, conducting global change studies in biological, chemical, physical, and oceanographic disciplines. This dataset consists of the underway measurements recorded during that specific voyage.

Use Cases

• Analyzing temporal patterns in oceanographic conditions based on underway time-series data.
• Studying biological or chemical changes along the ship's track in Antarctic waters.
• Correlating physical oceanographic measurements with other Antarctic climate datasets.
• Modeling ship-based observation routes and data collection strategies for polar research.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker.
• Covers a specific research voyage (LMG1109) with a known start and end point (Punta Arenas, Chile).
• Platform tags indicate it includes time-series and multi-disciplinary (biological, chemical, physical, oceanographic) measurements.

Limitations

• Last updated 2011-10-24 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
