RV Endeavour CTD Profiles from the European Shelf and Iberian Abyssal Plain

Research vessel profiles from the European Shelf and Iberian Abyssal Plain collected using a lowered CTD rosette system. Data from the CEFAS or DFR research cruise RV ENDEAVOUR 17/2007 likely includes pressure, temperature, and conductivity, with later cruises adding sensors like fluorometers. The down cast data is intended to provide a clean profile from the surface to near the seabed.

Use Cases

• Calculate salinity profiles based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze water column structure and stratification based on depth, temperature, and conductivity profiles.
• Study phytoplankton biomass distribution based on fluorometer data mentioned for later cruises.
• Investigate water clarity or sediment load using optical backscatter or transmissometer data referenced in the description.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system on station.
• The description specifies a geographic focus on the European Shelf with some data from the Iberian Abyssal Plain.
• Methodology notes that down cast data should provide a clean profile, and water bottle samples were taken for calibration.

Limitations

• Column-level documentation is absent; field semantics and the exact parameter set must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• The exact sensor configuration varies between cruises, affecting data format and available parameters.
