The dataset consists of processed CTD data collected at 69.746° N, 18.683° E (station KaF) in Kaldfjorden, Troms, between October 2017 and May 2018. CTD profiles were taken from small boat using a handheld SAIV a/s CTD sensor (SD208) with integrated sensors for dissolved oxygen (SAIV205), Fluorescence (Seapoint) and turbitidy (Seapoint), lowered by hand, and pulled up by winch or by hand, or from a research vessel using a Seabird Electronics SBE911plus CTD package. Information on which sensor was used is included in the dataset. Calibration of the conductivity sensors was done against salinity samples collected throughout the sampling period, as well as by sensor intercalibration. The SBE temperature and conductivity sensors were factory calibrated annually. Raw temperature and salinity profiles were processed using Matlab to control for and remove outliers, calibrate salinity, and convert in situ temperature to potential temperature. The dissolved oxygen sensor of the SAIV CTD was "calibrated" before each campaign according to the SAIV manual, but no calibration against water samples was done. Fluorescence and turbidity data are also provided uncalibrated. All variables were binned to regular 2 dbar depth bins.
