LMG9807: Underway Oceanographic Data from Antarctic Icebreaker Transit

1998 data from the R/V Laurence M. Gould's LMG9807 transit leg, which started and ended in Talcahuano, Chile. The dataset consists of underway data collected by the NSF-supported research icebreaker for global change studies in biological, chemical, physical, and oceanographic disciplines. It was last updated on September 4, 1998.

Use Cases

• Analyze physical oceanographic conditions during a ship transit based on the description of physical discipline data.
• Study biological or chemical indicators in Antarctic waters based on the mention of biological and chemical disciplines.
• Model time-series environmental trends from underway ship measurements.
• Correlate ship-collected data with other Antarctic research datasets.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides a specific temporal snapshot from the 1998 LMG9807 transit leg.

Limitations

• Last updated 1998-09-04 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.
