LMG0307: Antarctic Research Icebreaker Underway Data from 2003

Antarctic and Southern Ocean data was collected during the LMG0307 transit leg of the R/V Laurence M. Gould icebreaker in 2003. The dataset consists of underway measurements supporting global change studies in biological, chemical, physical, and oceanographic disciplines. The voyage started and ended in Punta Arenas, Chile.

Use Cases

• Analyze oceanographic conditions along a specific Antarctic transit route based on the underway data.
• Study temporal changes in marine biological or chemical parameters during the 2003 voyage.
• Correlate physical oceanographic measurements with other Antarctic climate datasets.
• Model ship-based transit paths and associated environmental sampling for logistical planning.

Strengths

• Data originates from a dedicated NSF-supported research icebreaker, the R/V Laurence M. Gould.
• Supports multidisciplinary global change studies across biological, chemical, physical, and oceanographic fields.
• Specific voyage details are provided: leg LMG0307 with start and end points in Punta Arenas, Chile.

Limitations
