NBP0705: Underway Oceanographic Data from Antarctic Research Vessel Transit

R/V Nathaniel B. Palmer collected this data during a 2007 transit leg for the U.S. Antarctic Program. The NSF-supported icebreaker gathers biological, chemical, physical, and oceanographic measurements for global change studies. This specific dataset, NBP0705, documents underway conditions from a round-trip voyage starting and ending in Punta Arenas, Chile.

Use Cases

• Modeling Southern Ocean physical properties based on underway oceanographic data.
• Analyzing temporal changes in biological and chemical indicators during a vessel transit.
• Calibrating satellite or model data with in-situ measurements from a research icebreaker.
• Studying vessel track and environmental correlations for Antarctic research logistics.

Strengths

• Data originates from the NSF-supported R/V Nathaniel B. Palmer, a dedicated Antarctic research icebreaker.
• Covers multiple disciplines: biological, chemical, physical, and oceanographic measurements.
• Provides a continuous time-series record of underway conditions during a specific transit leg.

Limitations

• Last updated 2007-06-25; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
