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 observatory 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 contains the temperature data of the Vemco temperature logger that was located at 16m depth in the deployment year 2010-2011. Several of the temperature loggers listed in the mooring diagram failed and thus did not record any data.
