LMG1712: Underway Oceanographic Data from Antarctic Research Cruise

The R/V Laurence M. Gould collected this underway data during leg LMG1712, which sailed from and returned to Punta Arenas, Chile. The dataset supports global change studies in biological, chemical, physical, and oceanographic disciplines for the U.S. Antarctic Program. The National Science Foundation (NSF) supported the research, and the data was last updated on December 20, 2017.

Use Cases

• Analyzing temporal patterns in oceanographic conditions based on underway data collection.
• Modeling biological or chemical changes in Antarctic waters based on the described global change studies.
• Correlating physical oceanographic measurements with other Antarctic environmental datasets.
• Studying ship-track based time-series data for the Southern Ocean region.

Strengths

• Data originates from the NSF-supported research icebreaker R/V Laurence M. Gould, an authoritative platform.
• Supports multi-disciplinary global change studies across biological, chemical, physical, and oceanographic fields.
• Specific cruise leg (LMG1712) and route (Punta Arenas to Punta Arenas) are documented.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2017-12-20 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
