Description
The NSF-supported research icebreaker Laurence M. Gould collected this data during leg LMG9907, which started and ended in Punta Arenas, Chile. The vessel operates year-round for the U.S. Antarctic Program, conducting studies in biological, chemical, physical, and oceanographic disciplines. The dataset was last updated in September 1999.
Use Cases
Analyzing oceanographic conditions during Antarctic transit based on the description of physical and chemical data collection.
Studying biological phenomena in polar regions based on the mention of biological discipline studies.
Modeling ship-based data collection routes and patterns based on the described transit from Punta Arenas, Chile.
Investigating long-term environmental changes in the Southern Ocean based on the global change studies focus.
