As part of the KROP - Kongsfjorden Rijpfjorden Observatory Programme, UiT The Arctic University of Norway and The Scottish Association for Marine Science maintain a marine obervatory in the high-Arctic location Kongsfjorden, Svalbard, since 2002. The observatory consists of an array of CTDs, temperature loggers, ADCPs and a sediment trap, in addition to various other instruments or installations that change from year to year. This dataset cotains the temperature and salinity data of the Seabird SBE37 MicroCAT that was located at 215m depth in the deployment year 2015-2016. At this deployment a wooden settlement was deployed to check for wood boring organisms, none recorded. A RAS500 water sampler and a SUNA nitrate sensor were deployed for a specific project, data available on request.
