LMG0910: Underway Data from Antarctic Research Icebreaker Laurence M. Gould

Underway data was collected during leg LMG0910 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. The dataset was last updated by SCIOPS on October 28, 2009.

Use Cases

• Analyze physical oceanographic conditions based on underway data collection.
• Study biological and chemical changes in Antarctic waters based on the described global change studies.
• Model ship-track environmental data based on the time-series nature of underway measurements.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields.

Limitations

• Last updated 2009-10-28 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
