LMG0911: Underway Data from Antarctic Research Icebreaker Laurence M. Gould

R/V Laurence M. Gould, a U.S. National Science Foundation-supported icebreaker, operates year-round for global change studies in biological, chemical, physical, and oceanographic disciplines. This dataset consists of underway data collected during leg LMG0911, which started and ended in Punta Arenas, Chile. The data was last updated on December 22, 2009, by the organization SCIOPS.

Use Cases

• Analyzing physical oceanographic conditions based on underway data collection.
• Studying biological and chemical changes in Antarctic waters based on the described global change studies.
• Modeling ship-track data and environmental variables for the specific research leg LMG0911.
• Investigating seasonal or annual patterns in Antarctic marine systems based on the vessel's year-round operation.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• The dataset is associated with a specific, documented research leg (LMG0911) with known start and end points.

Limitations

• Last updated 2009-12-22 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.
