RV CORYSTES 09/1997 High Resolution Conductivity-Temperature-Depth (CTD) Data
type: Dataset
description: 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.
