R/V Nathaniel B. Palmer NBP1105: Antarctic Underway Research 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 NBP1105, which started and ended in Punta Arenas, Chile. The data was last updated on November 4, 2011.

Use Cases

• Modeling Antarctic oceanographic conditions based on underway data collection.
• Analyzing time-series trends in physical oceanography for global change studies.
• Studying marine chemical or biological properties from Antarctic research cruise data.
• Correlating underway sensor data with other Antarctic environmental datasets.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides time-series underway data from a specific Antarctic research leg.

Limitations

• Last updated 2011-11-04 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.
