Ice Monitoring : Ice core analysis data from Salluit fjord, Deception Bay and Kangiqsujuaq (Nunavik, Canada) (2015 - 2018)

Ice cores from the landfast sea ice cover have been extracted twice a year in Salluit, Deception Bay and Kangiqsujuaq (Nunavik, Canada) since the 2016 winter season. This sampling takes place in January and April-May. The ice cores are extracted using a Kovacs ice corer. After the ice cores are photographed, four (4) slices are sawed off at equally-spaced depths along the core. These slices are photographed and then melted for ice salinity measurements. Slices are generally between 2 to 3 centimetres and have a diameter of 15 centimetres. In 2016, the salinity measurements were done on-site using a portable refractometer. Since 2017, salinity measurements were done at a higher precision using a laboratory conductivimeter. Several ice cores from every January/April field campaigns were scanned in a laboratory CT-scanner to obtain high-resolution 3D density measurements. Some of these were converted into porosity.
