NBP9707: Underway Oceanographic Data from Antarctic Research Vessel Transit

R/V Nathaniel B. Palmer, a U.S. Antarctic Program research icebreaker, collected this data during a 1997 transit leg. The dataset contains underway measurements from a round-trip voyage starting and ending in Punta Arenas, Chile, supporting global change studies across biological, chemical, physical, and oceanographic disciplines. It was last updated in October 1997.

Use Cases

• Analyzing physical oceanographic conditions during Antarctic transit based on underway data mentioned in the description.
• Studying temporal patterns in marine chemical or biological parameters collected during the voyage.
• Correlating in-situ Antarctic measurements with broader global change models referenced in the description.
• Investigating baseline environmental conditions for a specific Antarctic research cruise leg.

Strengths

• Data originates from a dedicated, NSF-supported research icebreaker, indicating a controlled collection environment.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Provides a specific temporal snapshot from a known cruise leg (NBP9707) in 1997.

Limitations

• Last updated 1997-10-27 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.
