NBP0901: Antarctic Ocean and Sea Ice Underway Data from the R/V Nathaniel B. Palmer

Antarctic underway data was collected by the NSF-supported research icebreaker R/V Nathaniel B. Palmer during leg NBP0901. The dataset captures ocean-sea ice interactions in the Pacific center of the Antarctic Dipole, starting and ending in Punta Arenas, Chile. It was last updated in February 2009.

Use Cases

• Modeling ocean-sea ice interactions in the Antarctic based on the described physical and oceanographic data.
• Analyzing time-series changes in the Antarctic marine environment based on the underway data collection.
• Studying the Antarctic Dipole phenomenon based on data from its Pacific center.
• Investigating global change impacts on Antarctic biological and chemical systems based on the multidisciplinary scope.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers multiple disciplines including biological, chemical, physical, and oceanographic, indicating multidisciplinary scope.
• Specific voyage leg (NBP0901) and geographic route (Punta Arenas to Punta Arenas) are documented.

Limitations

• Last updated 2009-02 25 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
