LMG0811: Underway Data from Antarctic Research Icebreaker Voyage

2008 data collected by the NSF-supported R/V Laurence M. Gould icebreaker during leg LMG0811. The dataset consists of underway measurements from a round-trip voyage between Punta Arenas, Chile, and Palmer Station, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The data is provided by SCIOPS.

Use Cases

• Analyzing oceanographic conditions along the Antarctic Peninsula based on underway measurements.
• Studying temporal changes in marine biological or chemical properties during an icebreaker transit.
• Correlating physical ocean data with other Antarctic environmental records from the same period.
• Modeling ship-based observation routes and data collection patterns for polar research.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers a specific, documented voyage leg (LMG0811) with a known start and end point.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2008-09-27 23:59:59.999000; freshness should be verified.
• Row count and file formats are unknown, which may limit suitability assessment.
