NBP9201: Underway Oceanographic Data from the Weddell-1 Rotation Cruise, 1992

R/V Nathaniel B. Palmer collected this underway data during its 1992 Weddell-1 rotation cruise to resupply a US-Russia ice camp. The NSF-supported icebreaker operates year-round for Antarctic research in biological, chemical, physical, and oceanographic disciplines. This leg started and ended in Punta Arenas, Chile.

Use Cases

• Analyze physical oceanographic conditions in the Weddell Sea based on the description of the cruise's purpose and location.
• Study temporal environmental changes in the Antarctic region based on the time-series nature of the underway data.
• Investigate chemical and biological parameters for global change studies as referenced in the vessel's research mission.
• Model ice-ocean-atmosphere interactions in polar regions based on the data's collection from a research icebreaker near a drifting ice camp.

Strengths

• Data originates from the NSF-supported research icebreaker R/V Nathaniel B. Palmer, a dedicated platform for Antarctic science.
• The cruise had a specific scientific mission to support a US-Russia drifting ice camp, suggesting focused data collection.
• Platform tags indicate the data is structured for time-series analysis.

Limitations

• Last updated 1992-05-16 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.
