LMG0306: Underway Data from Antarctic Research Icebreaker Transit

The 2003 LMG0306 leg of the R/V Laurence M. Gould collected underway data during a transit starting and ending in Punta Arenas, Chile. This dataset, supported by the NSF and the U.S. Antarctic Program, captures measurements for global change studies in biological, chemical, physical, and oceanographic disciplines. It was last updated on October 4, 2003.

Use Cases

• Analyze marine environmental conditions based on the described biological, chemical, and physical measurements.
• Study transit patterns and oceanographic features in Antarctic waters based on the underway data collection method.
• Model historical global change impacts in polar regions based on the multidisciplinary study focus.
• Correlate icebreaker-collected data with other Antarctic research datasets based on the described scientific support role.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for a holistic view.
• Provides a specific temporal snapshot from a 2003 Antarctic research transit.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2003-10-04 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
