LMG0108B: Antarctic Research Icebreaker Underway Data from 2001

R/V Laurence M. Gould LMG0108B - Transit is a dataset of underway data collected during a research cruise leg in support of the U.S. Antarctic Program. The NSF-supported icebreaker Laurence M. Gould operates year-round for global change studies in biological, chemical, physical, and oceanographic disciplines. This specific leg, LMG0108B, started and ended at Punta Arenas, Chile, and the data was last updated in November 2001.

Use Cases

• Analyzing oceanographic conditions along the transit route based on the description of underway data collection.
• Studying temporal changes in Antarctic marine environments based on the cruise's focus on global change.
• Correlating biological, chemical, and physical measurements from a polar research vessel based on the described multidisciplinary scope.
• Mapping the operational track and environmental context of a specific Antarctic research cruise leg.

Strengths

• Data originates from the NSF-supported research icebreaker Laurence M. Gould, a dedicated platform for Antarctic science.
• Dataset is focused on a specific, documented research leg (LMG0108B) with a known start and end point (Punta Arenas, Chile).
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic disciplines as described.

Limitations

• Last updated 2001-11-12 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.
