LMG0405: Antarctic Research Icebreaker Underway Data from 2004

R/V Laurence M. Gould, a U.S. Antarctic Program icebreaker, collected this underway data during leg LMG0405 in 2004. The transit data originates from a round-trip voyage starting and ending in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated by SCIOPS on May 25, 2004.

Use Cases

• Analyze transit patterns and environmental conditions in Antarctic waters based on the described underway data collection.
• Study correlations between physical oceanographic parameters and biological/chemical observations mentioned in the description.
• Model ship-based data collection routes and efficiency for polar research logistics.
• Investigate baseline conditions for global change studies in the Southern Ocean from the 2004 time period.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker, indicating a controlled collection environment.
• Specific voyage leg (LMG0405) and its start/end points (Punta Arenas, Chile) are clearly documented.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields.

Limitations

• Last updated 2004-05-25; 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.
