LMG1303: Underway Data from Antarctic Research Cruise

Punta Arenas, Chile served as the start and end point for the R/V Laurence M. Gould's LMG1303 research leg. This dataset contains underway measurements collected during that voyage in support of the U.S. Antarctic Program. The data was last updated in April 2013 and is hosted by NASA's Earthdata platform.

Use Cases

• Analyzing underway oceanographic conditions based on continuous shipboard measurements.
• Studying biological and chemical changes in Antarctic waters based on the described sampling disciplines.
• Investigating physical properties of the Southern Ocean based on the described research focus.
• Correlating ship-track data with other Antarctic time-series datasets based on the voyage's temporal and spatial scope.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
• Supports multi-disciplinary global change studies across biological, chemical, physical, and oceanographic fields.
• Provides a continuous time-series record from a specific Antarctic research voyage (LMG1303).

Limitations

• Last updated 2013-04-07 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.
