RV ENDEAVOUR 19/2007 Low Resolution Conductivity-Temperature-Depth (CTD) Data

European Shelf and Iberian Abyssal Plain oceanographic data collected from CEFAS research cruises. The data were gathered using a lowered CTD rosette system while vessels were stationary, providing profiles from surface to sea bed. The dataset likely contains 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 based on the described CTD profile collection method.
• Study phytoplankton distribution using data from later cruises that mention fluorometer sensors.
• Calibrate oceanographic models using the bottle sample data mentioned for calibration.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system.
• Coverage includes the broad European Shelf and extends to the Iberian Abyssal Plain.
• The description notes an evolution in sensor capabilities, suggesting a historical record of measurement practices.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.

Provenance

Source

CEFAS (Centre for Environment, Fisheries and Aquaculture Science) or DFR research cruises.

Collection Method

Collected using a lowered CTD rosette system on stationary research vessels, with water samples taken for calibration.

Time Range

Cruise identifier suggests data from 2007, but the description references 'early years' and 'subsequent years', indicating a potential time series.

Freshness

Last update date is unknown; freshness unverified.

Geography

Broadly covers the European Shelf with some data from the Iberian Abyssal Plain.
