RV CORYSTES 05/1999 High Resolution Conductivity-Temperature-Depth (CTD) Data

CEFAS research surveys collected this archive of Conductivity-Temperature-Depth (CTD) data from the European Shelf and Iberian Abyssal Plain. Data was gathered using a lowered CTD rosette system on stationary vessels, providing profiles from the surface to near the seabed. The dataset includes core parameters like pressure, temperature, and conductivity, with later cruises potentially adding sensors for fluorometry and light measurement.

Use Cases

• Calculate ocean salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical water column structure for oceanographic modeling based on high-resolution CTD profiles.
• Calibrate remote sensing or other oceanographic instruments using the in-situ bottle sample data mentioned.
• Study temporal changes in shelf sea properties by comparing data from different survey years.

Strengths

• Data collection followed a standardized methodology using a lowered CTD rosette system on research vessels.
• Core parameters allow for the calculation of salinity using established UNESCO formulations.
• The description specifies the geographic coverage includes the European Shelf and Iberian Abyssal Plain.

Limitations

• Column-level documentation is absent; field semantics and the full parameter list must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale projects.
• The exact sensor configuration and available parameters vary between cruises, as noted in the description.
