CALYPSO Pilot: Underway CTD and EcoCTD Ocean Profiles from the Alboran Sea (2018)

A 2018 pilot cruise in the Alboran Sea deployed Underway-CTD (UCTD) and bio-optically augmented EcoCTD probes from the NRV Alliance ship. The dataset contains vertical profiles of salinity, temperature, and concurrent bio-optical properties collected while steaming to achieve closely spaced horizontal measurements. Mathieu Dever of the University of Washington authored the cruise and data report focusing on these two underway systems.

Use Cases

• Mapping horizontal and vertical gradients of ocean properties based on closely spaced underway profiles.
• Studying correlations between physical (salinity, temperature) and bio-optical observations from concurrent EcoCTD measurements.
• Identifying coherent Lagrangian pathways from the surface to the ocean interior based on the survey trajectory.
• Developing or validating processing algorithms for underway CTD and bio-optical sensor data.

Strengths

• Data was collected during a coordinated scientific campaign involving two research vessels as part of an ONR Departmental Research Initiative.
• Includes concurrent physical and bio-optical observations from the specialized EcoCTD probe.
• The report describes important processing steps developed specifically for the EcoCTD data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
