LMG9801T: Underway Oceanographic Data from Antarctic Research Vessel Transit

1998 data from the NSF-supported icebreaker R/V Laurence M. Gould captures environmental conditions during a transit leg. This dataset likely contains measurements for biological, chemical, physical, and oceanographic global change studies. The leg started and ended at Fourchon, Louisiana, and was last updated on January 16, 1998.

Use Cases

• Analyzing oceanographic conditions during a research vessel transit based on the description of underway data.
• Studying temporal changes in marine environments based on the time-series nature of the data.
• Correlating physical and chemical ocean measurements for global change research as mentioned in the description.
• Modeling vessel-based environmental sampling routes for Antarctic studies.

Strengths

• Data originates from the NSF-supported R/V Laurence M. Gould, a dedicated Antarctic research vessel.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides a specific temporal snapshot from a 1998 transit leg.

Limitations

• Last updated 1998-01-16 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.
