Low-Resolution CTD Data from RV Endeavour Cruises on the European Shelf

Data collected from CEFAS research cruises in October 2007. The dataset contains low-resolution Conductivity-Temperature-Depth (CTD) profiles from the European Shelf and Iberian Abyssal Plain, gathered using a lowered rosette system while the vessel was stationary. The Government Digital Service provides this data, which includes core parameters like pressure, temperature, and conductivity, with salinity derivable using UNESCO formulations.

Use Cases

• Modeling water column stratification based on temperature and salinity profiles.
• Calibrating satellite-derived ocean color data using in-situ fluorometer readings.
• Studying particulate matter distribution using optical backscatter or transmissometer data.
• Analyzing primary production potential using photosynthetically available radiation (PAR) measurements.

Strengths

• Data collection follows a standardized down-cast protocol designed to produce clean profiles.
• Includes calibration samples from water bottles fired on the up-cast, which suggests quality control.
• Covers a specific geographic area (European Shelf and Iberian Abyssal Plain) from a known time period (October 2007).

Limitations

• Row count, file formats, and column-level documentation are unknown, requiring manual inspection after download.
• The exact sensor configuration varies between cruises, which may affect data consistency and comparability.
• Last update date is unknown; freshness unverified.
