NBP9706A: Underway Data from Antarctic Research Vessel Transit

The NSF-supported research icebreaker Nathaniel B. Palmer collected this underway data during leg NBP9706A. The transit started and ended at Punta Arenas, Chile, in support of the U.S. Antarctic Program's global change studies. The dataset was last updated on September 24, 1997.

Use Cases

• Analyzing physical oceanographic conditions during a specific Antarctic transit based on the description of underway data.
• Studying temporal patterns in marine biological or chemical properties based on the time-series nature of the data.
• Modeling ship-based environmental observations for climate research based on the global change studies context.
• Correlating transit route data with other Antarctic datasets based on the known start and end points.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional rigor.
• Dataset is associated with multidisciplinary global change studies in biological, chemical, physical, and oceanographic disciplines.
• Specific transit leg (NBP9706A) and its start/end points (Punta Arenas, Chile) are clearly documented.

Limitations

• Last updated 1997-09 24 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.
