NBP9306: Underway Data on UV Radiation Effects on Antarctic Phytoplankton

The NSF-supported research icebreaker Nathaniel B. Palmer collected this data set during leg NBP9306. It consists of underway data from a voyage starting and ending in Punta Arenas, Chile, focusing on the effects of UV radiation on phytoplankton photosynthesis in the Antarctic Marginal Ice Zone. The data was last updated in November 1993.

Use Cases

• Modeling phytoplankton photosynthesis rates in the Antarctic Marginal Ice Zone based on the described research focus.
• Analyzing temporal patterns of UV radiation exposure during the research cruise based on the time-series nature of the underway data.
• Studying the relationship between sea ice conditions and biological productivity in polar regions based on the 'Ice Zone' context.
• Comparing historical Antarctic marine data with modern observations based on the 1993 collection date.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting institutional rigor.
• Focuses on a specific and ecologically relevant phenomenon: UV radiation effects on phytoplankton.
• Provides a temporal snapshot of Antarctic conditions from a completed research leg.

Limitations

• Last updated 1993-11-11 23:59:59.999000; 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.
