Description
R/V Laurence M. Gould, a U.S. Antarctic Program icebreaker, collected this underway data during a 1998 transit from Punta Arenas, Chile, and back. The dataset supports global change studies across biological, chemical, physical, and oceanographic disciplines. It was last updated on April 9, 1998.
Use Cases
Analyze physical oceanographic conditions during Antarctic transit based on underway data mentioned in the description.
Study biological and chemical parameter trends in the Southern Ocean based on the multidisciplinary research focus.
Model vessel-based time-series data for climate change studies based on the global change research context.
Correlate environmental measurements along a specific ship track based on the described transit from Punta Arenas.
Strengths
Data originates from a dedicated NSF-supported research icebreaker, indicating a controlled collection environment.
Supports multidisciplinary global change studies across four listed disciplines: biological, chemical, physical, and oceanographic.
Covers a specific, documented transit leg (LMG9803) with a known start and end point (Punta Arenas, Chile).
