R/V Nathaniel B. Palmer NBP0710: Underway Oceanographic Data from Drake Passage

Underway data was collected during the NBP0710 research cruise of the NSF-supported icebreaker R/V Nathaniel B. Palmer. The leg started and ended at Punta Arenas, Chile, focusing on the Antarctic Circumpolar Current in Drake Passage. The dataset was last updated in December 2007.

Use Cases

• Analyzing the physical dynamics of the Antarctic Circumpolar Current based on underway measurements.
• Studying ocean transport processes in the Drake Passage based on the cruise's research focus.
• Investigating global change impacts in the Antarctic region based on the vessel's multidisciplinary mission.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
• Focuses on a critical oceanographic region, the Drake Passage, which is a key chokepoint for the Antarctic Circumpolar Current.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• 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.
