LMG0903: Underway Data from Antarctic Research Cruise, 2009

2009 data collected from the NSF-supported research icebreaker R/V Laurence M. Gould during leg LMG0903. The dataset consists of underway measurements supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The cruise operated in the Antarctic region, starting and ending in Punta Arenas, Chile.

Use Cases

• Analyze physical oceanographic conditions in the Antarctic region based on underway data.
• Study chemical properties of seawater related to global change based on the description.
• Investigate biological activity patterns in polar waters based on the multidisciplinary scope.
• Model environmental changes near the Larsen Ice Shelf system based on the cruise's research focus.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Specific cruise leg (LMG0903) and date (2009-04 -09) are documented, providing clear temporal context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2009-04-09 23:59:59.999000; freshness should be verified.
• Row count and file formats are unknown, which may limit suitability assessment.
