LMG9908: Underway Oceanographic Data from Antarctic Research Cruise

1999 data from the NSF-supported research icebreaker Laurence M. Gould captures continuous measurements during a scientific cruise in support of the U.S. Antarctic Program. This underway dataset likely contains biological, chemical, physical, and oceanographic variables collected to study global change. The leg started and ended at Punta Arenas, Chile.

Use Cases

• Analyzing temporal trends in oceanographic conditions based on continuous underway measurements.
• Correlating biological and chemical parameters for global change studies as mentioned in the description.
• Modeling physical ocean dynamics in Antarctic waters using time-series data from a research vessel.
• Establishing baseline environmental conditions for the Southern Ocean from a 1999 research cruise.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting controlled collection methods.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Provides a specific temporal snapshot from a completed research leg (LMG9908).

Limitations

• Last updated 1999-09-28 23:59:59.999000; 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.
