NBP0104: Antarctic Underway Hydrographic and Biological Data from R/V Nathaniel B. Palmer

R/V Nathaniel B. Palmer is a U.S. Antarctic Program research icebreaker conducting year-round global change studies. This dataset contains underway data from leg NBP0104, which started and ended in Punta Arenas, Chile. The data likely includes biological and physical hydrographic measurements collected during the cruise.

Use Cases

• Modeling Antarctic ocean circulation based on underway physical hydrographic data.
• Analyzing biological productivity patterns in the Southern Ocean based on biological measurements.
• Studying temporal changes in water properties during a research cruise based on time-series data.
• Calibrating regional oceanographic models with in-situ underway observations.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting high-quality collection standards.
• Covers both biological and physical oceanographic disciplines, enabling interdisciplinary analysis.

Limitations

• Last updated 2001-08-30 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.
