This data set of CTD and/or STD profiles at stations on the Faroe-Cape Wrath (FCW) hydrographic section has been collected on cruises under many different projects and programmes undertaken by Marine Scotland, the Faroe Marine Research Institute and the University of Hamburg since 2009. 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 Shetland to the Faroe Islands, at specific time intervals. Where stations were skipped or sections incomplete, a fill value has been applied.
