NBP0101: Underway Oceanographic Data from the R/V Nathaniel B. Palmer Antarctic Expedition

R/V Nathaniel B. Palmer leg NBP0101 collected underway data during a research cruise in the Indian Sector of the Southern Ocean. The NSF-supported icebreaker conducted global change studies in biological, chemical, physical, and oceanographic disciplines. The dataset originates from a voyage that started and ended in Hobart, Tasmania, and was last updated in March 2001.

Use Cases

• Modeling carbon export and primary production based on underway biogeochemical measurements.
• Analyzing physical oceanographic conditions in the Southern Ocean based on continuous underway sampling.
• Studying seasonal or spatial variability in Antarctic marine ecosystems based on the cruise track and collected data.
• Calibrating satellite ocean color data with in-situ measurements from the research voyage.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research icebreaker, suggesting authoritative collection methods.
• Focuses on the under-sampled Indian Sector of the Southern Ocean, a critical region for climate studies.
• Covers multiple oceanographic disciplines (biological, chemical, physical), likely enabling interdisciplinary analysis.

Limitations

• Last updated 2001-03-25 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
