LMG0204: Underway Oceanographic Data from Antarctic Research Vessel Transit

Antarctic waters and the Southern Ocean are covered by this dataset of underway measurements from the R/V Laurence M. Gould research icebreaker. The data was collected during leg LMG0204, which started and ended in Punta Arenas, Chile, in support of the U.S. Antarctic Program. The dataset was last updated in June 2002 and is provided by the organization SCIOPS.

Use Cases

• Modeling oceanographic conditions in Antarctic transit routes based on underway measurements.
• Analyzing temporal changes in water properties during a research voyage.
• Correlating biological and chemical data with physical oceanographic features mentioned in the description.
• Studying global change impacts in polar marine environments based on multidisciplinary data.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, suggesting authoritative collection.
• Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.

Limitations

• Last updated 2002-06-30 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.
