NBP1001: Underway Oceanographic Data from the Larsen Ice Shelf System, Antarctica

Antarctic underway data was collected during leg NBP1001 of the R/V Nathaniel B. Palmer icebreaker, which operated in support of the U.S. Antarctic Program. The dataset, supported by the NSF, consists of measurements from a research voyage that started and ended in Punta Arenas, Chile. It was last updated in March 2010.

Use Cases

• Analyzing abrupt environmental changes in the Antarctic based on the LARISSA project focus mentioned in the title.
• Studying physical oceanographic conditions from underway ship-based measurements described in the summary.
• Modeling ice shelf-ocean interactions in the Larsen system using data from a dedicated research expedition.
• Conducting time-series analysis of marine variables along the ship's track from Chile to Antarctica and back.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, the R/V Nathaniel B. Palmer.
• Focuses on a specific, high-impact geographic region: the Larsen Ice Shelf System in Antarctica.
• Covers a complete research leg (NBP1001) with a defined start and end point in Punta Arenas, Chile.

Limitations

• Last updated 2010-03-01 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.
