LMG0413A: Underway Data from Antarctic Research Icebreaker Laurence M. Gould

The R/V Laurence M. Gould LMG0413A dataset consists of underway data collected during a research leg in support of the U.S. Antarctic Program. The leg started and ended in Punta Arenas, Chile, and the data was collected for global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated on November 18, 2004.

Use Cases

• Analyzing oceanographic conditions along the vessel's route based on the underway data collection.
• Studying biological and chemical indicators for global change research in Antarctic waters.
• Correlating physical oceanographic measurements with other Antarctic climate datasets.
• Tracing the operational path and environmental context of a specific research icebreaker leg.

Strengths

• Data originates from the NSF-supported research icebreaker Laurence M. Gould, a known platform for Antarctic science.
• Dataset is focused on a specific, documented research leg (LMG0413A) with a clear start and end point in Punta Arenas, Chile.

Limitations

• Last updated 2004-11-18 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
