NBP0502: Underway Data from Antarctic Icebreaker Research Cruise

R/V Nathaniel B. Palmer, a U.S. Antarctic Program research icebreaker, collected this data during its 2005 SHALDRIL mission focused on shallow drilling. The dataset consists of underway measurements from leg NBP0502, which began and ended in Punta Arenas, Chile. It was contributed by SCIOPS and last updated in April 2005.

Use Cases

• Analyze physical oceanographic conditions during the Antarctic cruise based on underway data mentioned in the description.
• Study temporal patterns in marine chemical or biological properties collected by the icebreaker.
• Correlate ship-track data with geological sampling from the SHALDRIL shallow drilling mission.
• Model historical Antarctic continental margin conditions using expedition measurements.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection methods.
• Covers a specific Antarctic research expedition (SHALDRIL) with a defined route from Punta Arenas, Chile.

Limitations

• Last updated 2005-04-22 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.
