R/V Laurence M. Gould, an NSF-supported research icebreaker, collected this data during leg LMG0104 in support of the U.S. Antarctic Program. The dataset focuses on krill distribution, physiology, predation, and copepod prey abundance in the Southern Ocean. Data collection began and ended in Punta Arenas, Chile, with the dataset last updated in June 2001.
Use Cases
- Modeling krill population dynamics based on distribution and physiology data.
- Studying predator-prey relationships in the Southern Ocean based on krill and copepod abundance.
- Analyzing underway oceanographic conditions during the research cruise for context on biological observations.
Strengths
- Data originates from a dedicated NSF-supported research icebreaker, the R/V Laurence M. Gould.
- Dataset has a specific temporal anchor, with a last updated date of 2001-06-05.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2001-06-05 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
