LMG1404: Underway Data from Antarctic Research Cruise

The R/V Laurence M. Gould LMG1404 dataset contains underway data collected by the NSF-supported research icebreaker during a leg in the Southern Ocean. This leg started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The data was last updated in April 2014.

Use Cases

• Analyzing temporal patterns in oceanographic conditions based on the underway time-series data.
• Studying biogeochemical cycles in the Southern Ocean based on the described chemical and biological data collection.
• Modeling physical oceanographic processes in Antarctic waters based on the described physical discipline data.
• Investigating the impact of global change on Antarctic marine systems based on the dataset's stated purpose.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional quality control.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.

Limitations

• Last updated 2014-04-04 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.
