LMG9908B: Underway Data from Antarctic Research Vessel Transit

1999 data from leg LMG9908B of the NSF-supported research icebreaker R/V Laurence M. Gould. The dataset consists of underway measurements collected during a transit that started and ended in Punta Arenas, Chile, in support of global change studies in biological, chemical, physical, and oceanographic disciplines. It was last updated on October 21, 1999, by the organization SCIOPS.

Use Cases

• Analyzing marine environmental conditions during transit based on the description of global change studies.
• Studying temporal patterns in underway measurements from a research icebreaker.
• Correlating biological, chemical, and physical oceanographic data from a specific Antarctic voyage.
• Using the data as a historical baseline for comparison with contemporary Antarctic observations.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• The dataset is associated with a specific, documented research leg (LMG9908B) with known start and end points (Punta Arenas, Chile).
• Platform tags indicate it supports multidisciplinary global change studies.

Limitations

• Last updated 1999-10-21 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file format are unknown, which may limit suitability assessment.
