Temperature and Salinity from CTD Data on the JONSIS Section

This data set of CTD and/or STD profiles at stations on the Joint North Sea Information System (JONSIS) hydrographic section has been collected on cruises under many different projects and programmes undertaken by Marine Scotland since 1981. After initial quality assurance by the data originator, the individual CTD/STD profiles at stations on the section have been grouped together to form sections from Orkney eastwards, at specific time intervals. Where stations were skipped or sections incomplete, a fill value has been applied.

Data Dictionary

The temperature and conductivity (salinity) data have been screened by the data originator for spikes and other erroneous values and these have been removed.
The originator has also calibrated the conductivity/salinity sensor using salinity samples collected at sea. Salinity has been calculated using UNESCO 1983 algorithm.
