R/V Nathaniel B. Palmer NBP1104A: Antarctic Underway Research Data

Antarctic research data collected during the NBP1104A leg of the R/V Nathaniel B. Palmer icebreaker, which operated in support of the U.S. Antarctic Program. The dataset consists of underway measurements for global change studies across biological, chemical, physical, and oceanographic disciplines. The leg started and ended in Punta Arenas, Chile, and the data was last updated in September 2011.

Use Cases

• Analyze temporal patterns in oceanographic conditions based on underway time-series data.
• Study correlations between biological and chemical measurements in Antarctic waters.
• Model physical oceanographic processes using continuous ship-based observations.
• Investigate global change impacts on Antarctic marine systems using multidisciplinary data.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides continuous underway measurements, likely offering temporal consistency.

Limitations

• Last updated 2011-09-11 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
