LMG9911: Antarctic Research Vessel Underway Data from 1999

The NSF-supported research icebreaker Laurence M. Gould collected this data during leg LMG9911 in 1999. The dataset consists of underway measurements from a transit that started and ended in Punta Arenas, Chile. It was last updated on December 16, 1999, and is provided by the organization SCIOPS.

Use Cases

• Analyzing oceanographic conditions during Antarctic transit based on underway data mentioned in the description.
• Studying temporal patterns of physical and chemical properties in polar waters.
• Correlating biological observations with environmental data collected by the research vessel.
• Modeling vessel-based measurement series for climate change studies in the Southern Ocean.

Strengths

• Data originates from the NSF-supported research icebreaker Laurence M. Gould, a dedicated platform for Antarctic science.
• Covers multiple scientific disciplines including biological, chemical, physical, and oceanographic measurements.
• Provides a specific temporal snapshot from leg LMG9911 in 1999.

Limitations

• Last updated 1999-12-16 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.
