Description
R/V Laurence M. Gould leg LMG9804 collected underway data during a transit starting and ending in Punta Arenas, Chile. The NSF-supported research icebreaker operates year-round for the U.S. Antarctic Program, conducting studies in biological, chemical, physical, and oceanographic disciplines. This dataset was last updated on June 30, 1998.
Use Cases
Analyze temporal patterns in oceanographic conditions based on the time-series nature of the underway data.
Study biological and chemical changes in Antarctic waters based on the described multidisciplinary scope.
Model physical oceanographic processes for a specific vessel transit route based on the described geographic journey.
Correlate environmental measurements with global change phenomena based on the dataset's stated purpose.
Strengths
Data originates from a dedicated NSF-supported research icebreaker, suggesting a controlled collection environment.
Covers multiple scientific disciplines (biological, chemical, physical, oceanographic) as stated in the description.
