R/V Nathaniel B. Palmer NBP1303: Antarctic Research Cruise Underway Data

The NSF-supported research icebreaker Nathaniel B. Palmer operates year-round for the U.S. Antarctic Program. This dataset consists of underway data from leg NBP1303, which started and ended in Punta Arenas, Chile. The data supports global change studies in biological, chemical, physical, and oceanographic disciplines.

Use Cases

• Modeling oceanographic conditions in Antarctic waters based on underway physical measurements.
• Analyzing temporal trends in marine chemical properties for global change studies.
• Correlating biological observations with environmental data from the research cruise.
• Studying the physical oceanography of the Southern Ocean based on continuous underway sampling.

Strengths

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

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
