  3. Seawater temperature records for the UK Shelf - 16 - Cefas ScanFish - North & Celtic Seas

Seawater temperature records for the UK Shelf - 16 - Cefas ScanFish - North & Celtic Seas

Summary

This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. ScanFish is a high performance towed undulating CTD which was deployed by Cefas, initially, to aid the understanding of the coupling between physical and biological processes (Brown et al., 1996). It was towed behind the vessel at approximately 8 knots and undulated from the near surface (~4m) to within a few meters (~5m) of the bed, down to water depths of 135m. The vertical ascent rate was controlled so that each undulation covered a horizontal distance of 1km, regardless of water depth.

Lineage

Undulating profile data for temperature, salinity, fluorescence, ambient light, turbidity data for the top 120 m (approx.) of the water column. Accumulated data from a series of contracts looking at properties of seawater, investigating the extent of primary production and the existance of stratification and thermoclynes. Two cruises per year for 10 years. Data storage & processing constraints at the time of collection means that locations (individual records are notionally 4m apart horizontally) are likely to be accurate to the order of meters (this includes the assumptions of constant towing speed). Timings are based on an accurate start time and the recording of data at 1s intervals. The multiple sources are described in 17 separate metadata entries under the same Title, e.g. Seawater temperature records for the UK Shelf - 15 - RV Cefas Endeavour FerryBox Monitoring System. These data have been described in detail via the following publication. Morris, D. J., Pinnegar, J. K., Maxwell, D. L., Dye, S. R., Fernand, L. J., Flatman, S., Williams, O. J., and Rogers, S.
