LMG1803: Underway Data from Antarctic Research Cruise

Antarctic research data was collected by the NSF-supported icebreaker R/V Laurence M. Gould during leg LMG1803. The voyage started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated on April 9, 2018.

Use Cases

• Analyzing physical oceanographic conditions based on underway data mentioned in the description
• Studying biological and chemical changes in Antarctic waters based on the described global change studies
• Modeling ship-track time-series data for environmental monitoring based on the voyage information

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Last updated 2018-04 09 23:59:59.999000; freshness should be verified
