Greenland fjordsare currently undergoing significant ecosystem change due to unprecedented melting of the Greenland Ice Sheet (GrIS).The rapidly increasing discharge ofGrISmeltwaternot only influences circulation patterns and stratification of the water column, but it also introduces large fluxes of inorganic sediments and organic material that are suspended in the water column. These inputs can limit light availability to primary producers. However,data is still limited for mostGreenlandfjord systemsand there is an especial paucity of data showing yearly cycles. The Integrated Arctic Observation System (INTAROS) project funded by the European Commission’s H2020 programme allowed for the deployment of two moorings equipped with CTDs in the Young Sound fjord system––one in the inner fjord closest to GrIS meltwater discharge and another in the outer fjord region. This dataset reports the temperature and salinity recorded on these two moorings over 3 yearly cycles from August 2018 to August 2021. The moored CTDs wereRBR Maestro 3 and Concerto 3 and weredeployed at ~10 and ~20m in the inner and outer fjord respectively. Data were recorded at2 Hz with measurements taken at 5min–1h intervalsand raw data wereprocessed usingRBR Ruskin software.This datasetis made up of comma separated CSVfiles separated by mooring and year. We would like to thankCarl Isaksen and MarineBasis, Greenland Ecosystem Monitoring Programme ( https://g-e-m.dk ) for assistance during deployment.Themoorings werefunded by the EU Horizon2020 funded project INTAROS(grant no. 727890).
