R/V Nathaniel B. Palmer NBP1202: Underway Data from Antarctic Research Cruise

NBP1202 leg data was collected by the NSF-supported research icebreaker R/V Nathaniel B. Palmer in support of the U.S. Antarctic Program. The dataset consists of underway measurements from a voyage starting at Punta Arenas, Chile and ending at McMurdo Station. It was last updated on February 27, 2012.

Use Cases

• Analyze temporal patterns of oceanographic conditions based on underway time-series data.
• Study biological and chemical changes in Antarctic waters based on the described global change disciplines.
• Model physical oceanographic processes along the cruise track from Chile to McMurdo Station.
• Correlate in-situ underway measurements with other regional environmental datasets.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting controlled collection.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
• Provides a defined temporal snapshot from a specific research leg (NBP1202).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2012-02-27 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
