LMG1703: Underway Oceanographic Data from the R/V Laurence M. Gould Antarctic Cruise

The NSF-supported research icebreaker Laurence M. Gould operates year-round in support of the U.S. Antarctic Program. This data set consists of underway data from leg LMG1703, which started and ended at Punta Arenas, Chile. The dataset was last updated on April 9, 2017.

Use Cases

• Analyze temporal patterns of oceanographic conditions based on underway data.
• Study global change impacts in Antarctic ecosystems based on multidisciplinary measurements.
• Model physical oceanographic processes using continuous ship-track data.
• Correlate biological and chemical measurements with physical parameters from the research cruise.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, ensuring a controlled collection environment.
• Covers multiple scientific disciplines: biological, chemical, physical, and oceanographic.
• Provides continuous underway measurements along a specific cruise track (LMG1703).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2017-04-09 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
