R/V Nathaniel B. Palmer NBP9704B: Underway Antarctic Oceanographic Data

Underway data was collected during the NBP9704B research cruise of the R/V Nathaniel B. Palmer icebreaker in support of the U.S. Antarctic Program. The dataset, managed by SCIOPS, contains measurements from a transit leg that started and ended at Talcahuano, Chile. It was last updated in July 1997.

Use Cases

• Modeling oceanographic conditions along the ship's transit path based on the underway data collection.
• Analyzing time-series trends in Antarctic marine environments based on the continuous measurement nature of underway data.
• Studying global change in biological, chemical, and physical oceanographic disciplines as referenced in the description.
• Correlating ship-track data with other regional Antarctic datasets based on the geographic focus.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a scientific collection standard.
• Focuses on the Antarctic region, a critical area for global change studies.
• Covers multiple oceanographic disciplines (biological, chemical, physical) as stated in the description.

Limitations

• Last updated 1997-07 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 format are unknown, which may limit suitability assessment.
