LMG1409: Underway Oceanographic Data from Antarctic Research Cruise

The 2014 LMG1409 research leg collected underway data aboard the NSF-supported icebreaker R/V Laurence M. Gould. This data supports global change studies in biological, chemical, physical, and oceanographic disciplines. The cruise operated in the Antarctic region, starting and ending in Punta Arenas, Chile.

Use Cases

• Analyzing temporal patterns of oceanographic conditions based on underway data collection.
• Studying biological and chemical changes in Antarctic waters based on the described global change studies.
• Correlating physical oceanographic measurements with climate models based on the multidisciplinary research focus.
• Mapping the spatial distribution of marine properties along the cruise track based on the underway data type.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2014-10-21 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
