Trajectory-depth profile series from an autonomous underwater vehicle deployed during the 2012-2013 SPURS-1 oceanographic campaign. The dataset contains observations of chlorophyll, turbidity, oxygen, conductivity, salinity, and temperature from sensors on the Ecomapper AUV. Data was collected by the SPURS project team during two deployment days in September 2012.
Use Cases
- Analyze the correlation between salinity and temperature profiles from the CTD sensor to study water mass properties in the North Atlantic salinity maximum.
- Model chlorophyll and turbidity spatial distributions from the AUV trajectory data to assess biological activity and particle loads.
- Validate satellite-derived salinity products from Aquarius/SAC-D and SMOS using in-situ conductivity and salinity measurements.
- Investigate dissolved oxygen levels relative to depth and location for insights into ocean ventilation and biogeochemical cycles.
Strengths
- Data originates from a focused NASA-led process study (SPURS-1) employing state-of-the-art in-situ sampling.
- Includes multi-parameter sensor suite measurements (chlorophyll, turbidity, oxygen, CTD) on a single platform.
- Covers a defined 900 x 800-mile study area in the subtropical North Atlantic centered at 25N, 38W.
Limitations
- Very limited temporal coverage from only two deployment days in late September 2012.
- Spatial coverage is restricted to the AUV's operational path during its short deployment.
- Unknown sample size, row count, and data completeness for the sensor time series.
Provenance
- Source
- SPURS (Salinity Processes in the Upper Ocean Regional Study) project, via NASA Earthdata (POCLOUD).
