LMG9808A: Underway Data from Antarctic Research Vessel Transit

1998 data from the R/V Laurence M. Gould's LMG9808A transit leg, which started and ended in Punta Arenas, Chile. The dataset contains underway measurements collected by the NSF-supported research icebreaker for global change studies in biological, chemical, physical, and oceanographic disciplines. It was last updated in October 1998.

Use Cases

• Analyze physical oceanographic conditions during a specific Antarctic transit based on the description of underway data.
• Study temporal patterns in marine biological or chemical parameters along a vessel track based on the description of global change studies.
• Correlate underway measurements with other Antarctic datasets for climate research based on the described multidisciplinary scope.

Strengths

• Data originates from the NSF-supported R/V Laurence M. Gould, a dedicated Antarctic research vessel.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.
• Provides a specific temporal anchor with a last update date of 1998-10-08.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1998-10-08 23:59:59.999000; freshness should be verified.
• Row count and file formats are unknown, which may limit suitability assessment.
