Physical trajectory profile data was collected by a glider (ud_134) deployed by the University of Delaware. The mission conducted cross-canyon transects in the Palmer Deep near Anvers Island, Antarctica, from January 5 to 21, 2015. Data includes measurements of temperature, salinity, conductivity, and density, archived by NOAA's National Centers for Environmental Information.
Use Cases
- Modeling coastal ocean currents and upwelling events based on physical property transects.
- Investigating links between oceanographic conditions and Adélie penguin foraging ecology as described in the mission.
- Analyzing water column structure (temperature, salinity, density) in the Palmer Deep canyon system.
- Calibrating or validating remotely sensed surface current maps from High Frequency Radar (HFR) networks.
Strengths
- Data covers a specific 17-day mission with a clear scientific objective.
- Includes core physical oceanographic properties: temperature, salinity, conductivity, and density.
- Data was aggregated and checked for compliance by the IOOS National Glider Data Assembly Center before archival.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last updated 2015-01-21 00:00:00; freshness should be verified.
