NBP0205: Antarctic Underway Oceanographic Data from R/V Nathaniel B. Palmer

R/V Nathaniel B. Palmer, a U.S. Antarctic Program research icebreaker, collected this data during its 2002 NBP0205 voyage. The dataset contains underway measurements from a round-trip expedition originating and ending in Punta Arenas, Chile. NSF-supported scientists gathered biological, chemical, physical, and oceanographic data for global change studies.

Use Cases

• Modeling latitudinal gradients in marine microbial communities based on the described biological sampling.
• Analyzing underway physical oceanography data for changes in water properties along the cruise track.
• Studying the impact of ultraviolet radiation (UVR) on bacterioplankton as suggested by the project title.
• Correlating chemical and biological measurements to understand Antarctic marine biogeochemistry.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research vessel, ensuring authoritative collection.
• Covers multiple oceanographic disciplines (biological, chemical, physical) as stated in the description.
• Provides a specific temporal anchor with a last updated date of 2002-10-17.

Limitations

• Last updated 2002-10-17 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.
