LMG1706: Underway Oceanographic Data from Antarctic Research Cruise

The R/V Laurence M. Gould LMG1706 dataset contains underway data collected by the NSF-supported research icebreaker during a leg that started and ended in Punta Arenas, Chile. This data supports global change studies in biological, chemical, physical, and oceanographic disciplines for the U.S. Antarctic Program. The dataset was last updated on July 24, 2017.

Use Cases

• Analyze physical oceanographic conditions along the cruise track based on the description of underway data.
• Study temporal changes in water properties for global change research based on the expedition's stated purpose.
• Model biogeochemical cycles in Antarctic regions based on the multidisciplinary scope of the research program.
• Correlate underway measurements with other Antarctic datasets based on the vessel's role in the U.S. Antarctic Program.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating institutional support.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields.
• Dataset is associated with a specific, documented research expedition leg (LMG1706).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2017-07-24 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
