R/V Laurence M. Gould LMG9902: Antarctic Underway Research Data

NSF-supported research icebreaker Laurence M. Gould collected this underway data set during leg LMG9902. The leg operated in support of the U.S. Antarctic Program, conducting global change studies in biological, chemical, physical, and oceanographic disciplines. Data collection for this leg concluded on March 17, 1999.

Use Cases

• Analyze temporal patterns in Antarctic oceanographic conditions based on underway data.
• Study global change impacts on polar marine biology based on the described biological discipline.
• Model physical oceanographic processes in Antarctic waters based on the described physical discipline.
• Investigate chemical properties and cycles in the Southern Ocean based on the described chemical discipline.

Strengths

• Data originates from the NSF-supported research icebreaker Laurence M. Gould, an authoritative platform for Antarctic research.
• Covers multiple scientific disciplines including biological, chemical, physical, and oceanographic studies.
• Provides a specific temporal snapshot with a recorded last update date of 1999-03-17.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1999-03-17; freshness should be verified for contemporary applications.
• Row count and file size are unknown, which may limit suitability assessment.
