NBP9206: Underway Oceanographic Data from the Weddell Sea, 1992

R/V Nathaniel B. Palmer collected this underway data during its 1992 Antarctic research cruise NBP9206. The dataset captures environmental conditions in the Weddell Sea, focusing on trophic coupling between mesopelagic and sea-ice communities. It was gathered by the NSF-supported icebreaker and last updated in October 1992.

Use Cases

• Modeling trophic coupling between mesopelagic and sea-ice communities based on the research focus described.
• Analyzing time-series changes in Antarctic marine conditions based on the 'underway data' nature of the collection.
• Studying the physical and biological oceanography of the Weddell Sea based on the geographic scope.
• Investigating global change impacts on polar regions based on the vessel's stated mission for global change studies.

Strengths

• Data originates from the NSF-supported research icebreaker R/V Nathaniel B. Palmer, a dedicated platform for Antarctic science.
• Focuses on a specific and ecologically significant Antarctic region, the Weddell Sea.
• Captures a temporal snapshot from a defined research leg, NBP9206, in 1992.

Limitations

• Last updated 1992-10-16 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.
