RV Endeavour 03/2007 Low-Resolution CTD Data from the European Shelf

RV Endeavour 03/2007 Low Resolution Conductivity-Temperature-Depth (CTD) Data were collected by CEFAS (or DFR) research cruises. The data broadly cover the European Shelf and the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The dataset includes core parameters like pressure, temperature, and conductivity, with salinity derivable, and later cruises added sensors like fluorometers and transmissometers.

Use Cases

• Calculate water salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical ocean structure and water mass properties based on CTD profiles from the surface to near the seabed.
• Calibrate satellite-derived oceanographic data using in-situ bottle sample measurements mentioned in the description.
• Study temporal changes in marine ecosystems by comparing sensor data like fluorescence (chlorophyll) across different cruises.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system, which is designed for clean down-cast profiles.
• The description specifies the use of water bottle samples for calibration, which suggests a process for data quality control.
• Coverage includes the European Shelf and the Iberian Abyssal Plain, providing a defined geographic scope.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics and the exact parameters for the 03/2007 cruise must be inferred after download.
• The exact sensor configuration varies between cruises, and the data format of output files reflects this, potentially complicating consistency.

Provenance

Source

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

Collection Method

Data collected on station using a lowered CTD rosette system, with profiles from surface to near seabed and bottle samples fired on the up-cast for calibration.

Time Range

Specific cruise in March 2007; the description references data from 'early years' and 'subsequent years', suggesting a longer program.

Freshness

Last update date is unknown; freshness unverified.

Geography

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