LMG0905: Underway Data from Antarctic Research Cruise on R/V Laurence M. Gould

The 2009 LMG0905 research leg collected underway data from the NSF-supported icebreaker R/V Laurence M. Gould during a round-trip voyage from Punta Arenas, Chile. The dataset supports global change studies in biological, chemical, physical, and oceanographic disciplines in the Antarctic region. It was aggregated by SCIOPS and last updated on June 10, 2009.

Use Cases

• Analyzing environmental conditions during the research cruise based on the described underway data collection.
• Studying linkages between mitochondrial function and thermal tolerance in Antarctic fish based on the dataset's stated research focus.
• Modeling physical and chemical oceanographic parameters for the Antarctic region based on the described global change studies.
• Correlating ship-track data with biological sampling events based on the voyage's described purpose.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Specific voyage leg (LMG0905) and its route (Punta Arenas to Punta Arenas) are clearly documented.

Limitations

• Last updated 2009-06-10 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.
