LMG1106A: Underway Oceanographic Data from Antarctic Research Cruise

Antarctic waters and the Southern Ocean are the focus of this dataset, which contains underway measurements from a 2011 research cruise aboard the NSF-supported icebreaker R/V Laurence M. Gould. The data was collected by the organization SCIOPS on leg LMG1106A, which traveled from Punta Arenas, Chile, and returned to the same port. It supports global change studies across biological, chemical, physical, and oceanographic disciplines.

Use Cases

• Modeling oceanographic conditions in the Southern Ocean based on underway physical measurements.
• Analyzing temporal changes in marine chemistry based on underway chemical data collection.
• Studying biological activity patterns in Antarctic waters based on underway biological sampling.
• Calibrating satellite-derived ocean data with in-situ measurements from the research cruise.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting high-quality collection methods.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for a holistic view.

Limitations

• Last updated 2011-08-20 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.
