LMG9808: Underway Oceanographic Data from Antarctic Research Vessel Transit

The R/V Laurence M. Gould LMG9808 dataset contains underway data collected during a research transit leg of the NSF-supported icebreaker. This leg operated in support of the U.S. Antarctic Program, conducting global change studies in biological, chemical, physical, and oceanographic disciplines. The transit started and ended in Punta Arenas, Chile, with data last updated in September 1998.

Use Cases

• Analyze physical oceanographic conditions during Antarctic transit based on underway data mentioned in the description.
• Study temporal patterns in biological or chemical parameters collected during the research cruise.
• Model ship-based observations for global change studies in polar regions.
• Correlate underway measurements with other Antarctic research datasets from the same time period.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional credibility.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.

Limitations

• Last updated 1998-09-20 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.
