LMG0717: Antarctic Underway Oceanographic Data from R/V Laurence M. Gould

Underway data were collected during leg LMG0717 of the NSF-supported research icebreaker R/V Laurence M. Gould. The dataset originates from a 2007 research cruise focused on testing the Polar Gateway Glaciation Hypothesis in the Drake Passage. The voyage started and ended in Punta Arenas, Chile.

Use Cases

• Analyze water-mass properties and changes based on underway oceanographic measurements.
• Study the kinematic history of Drake Passage opening mentioned in the research title.
• Model past ice-volume and sedimentary records to test glaciation hypotheses.
• Correlate physical and chemical oceanographic data with global change studies.

Strengths

• Data originates from a dedicated NSF-supported Antarctic research vessel.
• Cruise track is specified, starting and ending in Punta Arenas, Chile.

Limitations

• Last updated 2007-12-21 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
