The data in this archive were collected from CEFAS (Or DFR) research cruises. They broadly cover the European Shelf with some data from the Iberian Abysal Plain. Data were collected using the lowered CTD rosette system which is used when the vessel is stationary. Usually bottles were fired at particular depths and samples taken for calibration. In early years only a limited set of parameters were collected. Notably Pressure (Depth), Temperature and Conductivity (CTD). From Conductivity Salinity can be calculated using the UNESCO 1978,1983 formulations . In subsequent years more sensors have been added, notably fluorometers, Optical back scatter or transmissometers and Light (PAR, photo synthetically available radiation). The exact configuration varies between cruises and this is reflected in the data format of the output files. Data was collected from research vessels on station, a profile from the surface to near the sea bed is undertaken. The down cast data should be a clean profile. Water bottles for sample collection and calibration are fired on the up cast.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Data was collected via the CTD rosette system using either a Guildine CTD or from approximately 1993 an Falmouth Scientific Instruments Integrated CTD. In addition to the CTD, additional instruments are Sea Point Fluorometers, Dr Haardt Fluorometers, Transmissometers, Sea Point Optical Backscatter, LICOR Light Sensors (PAR) Instruments were usually calibrated where possible before the cruise and post cruise, in a water bath, for Temperature and using a pressure test vessel for pressure. Calibrations for Salinity were performed with reference to Salinity samples collected. Calibration of the fluorescence to generate chlorophyll was by comparison to the collected samples. Similarly suspend load would be calibrated to samples collected and filtered. The light sensor was calibrated in a dark light box. The specific calibration values (where available) are stored with each cruise data set. Processing of the data was initially performed using the instrument specific programs to generate ASCII files (e.g FSIpost) a suite of programs developed at CEFAS was then used to generate calibrated files and generate the processed information. +------------+---------+--------------------------------+ |Pres |DBAR |Pressure in Dbar | +------------+---------+--------------------------------+ |Temp |Deg C |Temperature in Celsius | +------------+---------+--------------------------------+ |SALT | |Salinity (PSS 78) | +------------+---------+--------------------------------+ |PTEMP |Deg C |Potential Temperature | +------------+---------+--------------------------------+ |SNDVEL |m/sec |Sound Velocity | +------------+---------+--------------------------------+ |SIG-TH |KG/m3 |Density Sigma theta | +------------+---------+--------------------------------+ |SIGM |KG/m3 |Density Sigma T | +------------+---------+--------------------------------+ |SVAN |10*8 |Specific Volume Anomaly | +------------+---------+--------------------------------+ |DYNHT |m |Dynamic Height | +------------+---------+--------------------------------+ |BVF |CPH |Brunt Vaisala Frequency | +------------+---------+--------------------------------+ |Depth |m |Depth (integrated from density) | +------------+---------+--------------------------------+ |Transmission|raw | | | |volts | | +------------+---------+--------------------------------+ |Susp Load |mg/l |Calibrated transmission (or | | | |OBS) | +------------+---------+--------------------------------+ |RADI |lng A |raw light sensor | +------------+---------+--------------------------------+ |PAR |uE/M2/S |Calibrated light | +------------+---------+--------------------------------+ |Fluor |Volt |Uncalibrated fluorometer | +------------+---------+--------------------------------+ |Chl |mg/m3 |Calibrated fluorometer | +------------+---------+--------------------------------+ |
