LMG1808: Underway Data from Antarctic Research Icebreaker Laurence M. Gould

Underway data was collected during leg LMG1808 of the NSF-supported research icebreaker R/V Laurence M. Gould. The leg started and ended in Punta Arenas, Chile, in support of the U.S. Antarctic Program for global change studies. The dataset was last updated by SCIOPS on October 17, -2018.

Use Cases

• Analyzing oceanographic conditions along the vessel's transit route based on the underway data collection.
• Studying temporal changes in marine environments based on the time-series nature of the underway measurements.
• Correlating biological and chemical observations with physical oceanographic data collected during the Antarctic research leg.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• The dataset covers a specific research leg (LMG1808) with a defined start and end point in Punta Arenas, Chile.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2018-10-17 23:59:59.999000; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
