LMG0603: Surface pCO2 Underway Data from the Drake Passage

The Drake Passage and Antarctic region are covered by this dataset of underway measurements from the R/V Laurence M. Gould research icebreaker. It was collected during leg LMG0603, which started and ended in Punta Arenas, Chile, and is supported by the NSF for the U.S. Antarctic Program. The data focuses on processes driving spatial and temporal variability of surface partial pressure of carbon dioxide (pCO2).

Use Cases

• Modeling carbon dioxide fluxes between the ocean and atmosphere based on surface pCO2 measurements.
• Analyzing spatial variability of ocean chemistry in the Drake Passage based on underway survey data.
• Studying temporal changes in surface ocean carbon content in Antarctic waters.
• Investigating processes driving biogeochemical cycles in polar marine environments.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, the R/V Laurence M. Gould.
• The dataset is focused on a specific, scientifically critical region: the Drake Passage.

Limitations

• Last updated 2006-04-04 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.
