2000 data from leg LMG0003A of the NSF-supported research icebreaker R/V Laurence M. Gould, which operates year-round for the U.S. Antarctic Program. The dataset consists of underway measurements collected on a voyage that started and ended in Punta Arenas, Chile, supporting global change studies in biological, chemical, physical, and oceanographic disciplines. It is provided by the organization SCIOPS via NASA's Earthdata platform.
Use Cases
- Analyzing oceanographic conditions along the ship's track based on the underway data collection method.
- Studying biological and chemical indicators of global change in Antarctic waters as referenced in the description.
- Correlating physical oceanographic measurements with other Antarctic climate datasets.
- Validating satellite-derived ocean data with in-situ measurements from a dedicated research vessel.
Strengths
- Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
- Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) for integrated analysis.
- Specific voyage leg (LMG0003A) and its start/end points (Punta Arenas, Chile) are clearly documented.
Limitations
- Last updated 2000-04-21 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file format are unknown, which may limit suitability assessment.
