NBP1107: Antarctic Circumpolar Current Underway Data from Drake Passage

The NSF-supported research icebreaker Nathaniel B. Palmer collected this underway data set during leg NBP1107 in support of the U.S. Antarctic Program. The data supports global change studies in biological, chemical, physical, and oceanographic disciplines. The cruise leg started and ended at Punta Arenas, Chile.

Use Cases

• Modeling the dynamics of the Antarctic Circumpolar Current based on underway physical oceanographic data.
• Analyzing transport properties in the Drake Passage based on time-series measurements.
• Studying global change impacts on Antarctic marine systems based on multidisciplinary cruise data.
• Validating satellite or model-derived oceanographic data with in-situ underway measurements.

Strengths

• Data originates from the NSF-supported research icebreaker Nathaniel B. Palmer, a dedicated platform for Antarctic science.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic disciplines.

Limitations

• Last updated 2007-12-06 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.
