Approximately 1000 profiles of temperature, salinity, dissolved oxygen, fluorescence, and optical backscatter were collected by a pair of ocean gliders. This data set consists of underway data from leg LMG1411 on the NSF-supported research icebreaker R/V Laurence M. Gould, which operates in support of the U.S. Antarctic Program. The leg started and ended in Punta Arenas, Chile, and the data was last updated in December 2014.
Use Cases
- Analyze frontal dynamics in the Southern Drake Passage based on high-resolution temperature and salinity profiles.
- Study phytoplankton biomass distribution based on fluorescence and optical backscatter data.
- Investigate water mass properties and oxygen variability based on dissolved oxygen and salinity measurements.
- Validate regional ocean circulation models based on underway data collected by research vessels.
Strengths
- Approximately 1000 profiles collected by ocean gliders, suggesting a detailed spatial/temporal series.
- Data covers multiple oceanographic variables: temperature, salinity, dissolved oxygen, fluorescence, and optical backscatter.
- Collected by the NSF-supported R/V Laurence M. Gould, a dedicated Antarctic research vessel.
Limitations
- Last updated 2014-12-21 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
