Description
Research vessel data collected by CEFAS (or DFR) using a lowered CTD rosette system while the vessel was stationary. The data broadly cover the European Shelf and the Iberian Abyssal Plain, with profiles from the surface to near the sea bed. Early years likely contain core parameters like pressure, temperature, and conductivity, while later cruises may include additional sensors such as fluorometers.
Use Cases
Calculate salinity profiles based on conductivity, temperature, and pressure data using UNESCO formulations.
Analyze vertical water column structure based on down cast CTD profiles.
Calibrate sensor readings using water sample data collected from bottles fired on the up cast.
Study temporal changes in marine parameters by comparing data from different research cruises.
Strengths
Data collection follows a standardized methodology using a lowered CTD rosette system on research vessels.
The description specifies the geographic coverage of the European Shelf and Iberian Abyssal Plain.
The methodology describes a clean down cast profile and calibration samples from the up cast.
Limitations
Row count, file formats, and column-level documentation are unknown, requiring manual inspection after download.
The exact sensor configuration and available parameters vary between cruises, as noted in the description.
Last update date is unknown; freshness unverified.
Provenance
Source
Government Digital Service, likely originating from CEFAS (Centre for Environment, Fisheries and Aquaculture Science) or DFR.
Collection Method
Collected from research vessel cruises using a lowered CTD rosette system, with water samples taken for calibration.
Time Range
Specific temporal coverage is unknown; the title references a cruise from April 1985.
Freshness
Last updated date is unknown.
Geography
Broadly covers the European Shelf with some data from the Iberian Abyssal Plain.
