NBP9706B: Antarctic Research Vessel Underway Data from 1997

Underway data was collected during leg NBP9706B of the NSF-supported research icebreaker R/V Nathaniel B. Palmer. The leg operated in support of the U.S. Antarctic Program, conducting global change studies in biological, chemical, physical, and oceanographic disciplines. The voyage started and ended at Punta Arenas, Chile in 1997.

Use Cases

• Analyze physical oceanographic conditions in Antarctic waters based on the description of underway data collection.
• Study temporal patterns in marine chemical or biological parameters based on the time-series nature of the data.
• Model historical environmental baselines for global change research based on the dataset's stated purpose.
• Correlate vessel-track data with other Antarctic research based on the transit leg description.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.
• Provides a specific temporal reference with a last updated date of 1997-10-04.

Limitations

• Last updated 1997-10-04 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.
