SPURS-1: Ecomapper AUV Ocean Sensor Data from the North Atlantic

Two days of deployments on 29 and 30 September 2012 during the SPURS-1 field campaign. The data consist of trajectory-depth profile series from an autonomous underwater vehicle (Ecomapper) measuring chlorophyll, turbidity, oxygen, conductivity, salinity, and temperature in a high-salinity region of the subtropical North Atlantic. This dataset was created by the National Aeronautics and Space Administration as part of a study on upper-ocean salinity processes.

Use Cases

• Modeling salinity structure and balance based on conductivity and temperature profiles.
• Analyzing correlations between biological activity (chlorophyll) and water clarity (turbidity) in a high-evaporation region.
• Studying dissolved oxygen variations in relation to physical oceanographic processes.
• Validating satellite-derived salinity fields from Aquarius/SAC-D and SMOS with in-situ sensor data.

Strengths

• Data collected during a focused, multi-cruise campaign (SPURS-1) spanning 2012-2013.
• Includes observations from a suite of sensors (CTD, chlorophyll, oxygen, turbidity) on a state-of-the-art AUV.
• Covers a defined study area of 900 x 800 miles centered at 25N, 38W.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to two specific deployment days in September 2012.
